Jabra Enhance

Short answer: the “best” hearing aids most people actually buy/use

If you want premium prescription hearing aids, start with these brands/models:

1. Phonak Audéo Sphere Infinio / Ultra Sphere — best bet for speech in noisy restaurants, meetings, crowds.
2. Oticon Intent — excellent all-around premium choice; very natural spatial sound and strong speech handling.
3. ReSound Vivia — great if you want a small RIC, strong app/connectivity, Bluetooth LE Audio/Auracast.
4. Starkey Omega AI — strong for custom/in-the-ear options, AI processing, and health/app features.
5. Signia Pure Charge&Go IX / BCT IX — strong for group conversations, own-voice comfort, and broad Bluetooth compatibility.
6. Widex Allure — best choice to try if you care most about natural sound, music, and sound quality.

For “what people actually use,” recent HearingTracker survey data found Phonak was the most common brand among respondents, followed by Oticon, ReSound, Starkey, Jabra/Beltone, and Signia; Widex was among the higher-priced premium brands. (hearingtracker.com)

My practical recommendations by situation

Best value pick: Costco

If you are in the U.S. and want a real hearing-aid fitting without paying private-clinic prices, Costco is hard to beat. In 2026, Costco’s main prescription options are listed around $999–$1,700 per pair, including Rexton Reach, Philips HearLink, Jabra Enhance Pro 30, and Sennheiser Sonite Rise. (hearingtracker.com)

My Costco shortlist:

• Jabra Enhance Pro 30 — comparable lineage to ReSound/GN tech; strong choice for speech-in-noise and connectivity.
• Philips HearLink 9050 — good Oticon-family alternative; often liked for a more natural sound.
• Rexton Reach — Signia-family tech; good value and often good for group conversation handling.
• Sennheiser Sonite Rise — Sonova-family option; worth trying if available locally.

If your loss is complex, severe, one-sided, or you need lots of counseling and fine-tuning, a private audiologist may still be worth it.

Best OTC picks

OTC hearing aids are only intended for adults 18+ with perceived mild to moderate hearing loss, not severe/profound loss. The FDA says OTC aids can be bought online or in stores without an audiologist, while prescription aids are fitted/programmed by a licensed professional and may be appropriate for all levels of loss. (fda.gov)

Good OTC options:

• Jabra Enhance Select 700 — my OTC pick if you want a recognizable brand, remote audiologist support, Bluetooth LE Audio, and a more premium experience. HearingTracker lists it as a top OTC pick for remote care. (hearingtracker.com)
• Elehear Beyond Pro — strong value OTC pick; HearingTracker ranked it their overall OTC top pick in 2026, citing lab performance and remote support. (hearingtracker.com)
• Apple AirPods Pro 2/3 hearing feature — not a replacement for all-day hearing aids, but a low-cost way to experiment if you have mild–moderate loss; the FDA authorized Apple’s Hearing Aid Feature as OTC hearing-aid software for compatible AirPods Pro. (fda.gov)

Important buying advice

The fitting matters as much as the brand. A $6,000 pair fitted poorly can be worse than a $1,600 Costco pair fitted well. Ask for:

• Real-ear measurement / probe-mic verification
• A trial period of at least 30–60 days
• Clear warranty/repair terms
• Follow-up visits included
• Help pairing with your phone
• Multiple programs for quiet, noise, music, and restaurants

Also, don’t buy OTC first if you have sudden hearing loss, ear pain, drainage, dizziness/vertigo, major one-sided hearing loss, or hearing loss under age 18—get medical/audiology evaluation.

Bottom line:
If money is not the main issue, trial Phonak Sphere, Oticon Intent, ReSound Vivia, or Widex Allure through a good audiologist. If value matters most, start at Costco. If your loss is mild–moderate and you’re comfortable self-managing, try Jabra Enhance Select 700 or Elehear Beyond Pro.

Hearing aids generally fall into two categories these days — prescription (fitted by an audiologist) and over-the-counter/direct-to-consumer (OTC) — and the "best" choice really depends on your budget, severity of hearing loss, and whether you want professional fitting support.

Prescription Hearing Aids: The "Big Six" Manufacturers

Nearly all audiologist-fitted hearing aids come from a small group of major manufacturers who dominate the professional market: Nearly all locally prescribed hearing aids are produced by a handful of major brands, known as the "Big 6." These companies invest millions in research and development, often leading the industry in innovation and technology. While there are some style and philosophy differences between brands, they generally offer the same advanced features and similar price points.

Within this group, a few stand out for specific strengths:

• Jabra Enhance – Widely rated as a top overall pick. Jabra Enhance Select 700 offers top-notch sound quality, long battery life, a long trial period, and industry-leading post-purchase care from hearing experts. It's also praised elsewhere for premium sound, LE Audio, Auracast, and top-tier remote audiology care in a tiny, discreet design.
• ReSound – one of the top 6 manufacturers and has some great tools for the hearing-impaired, including state-of-the-art devices, accessories, and smartphone apps, according to an audiologist. Its Vivia line is ReSound's newest hearing aid platform, with the premium Vivia 9 adding a dedicated Deep Neural Network (DNN) chip designed to further improve speech clarity when competing sounds are present.
• Oticon – boasts a reliable, ever-improving portfolio made specifically with the user in mind, with an onboard Deep Neural Network in the Oticon Zeal offering a database of up to 12 million real-world sound scenes.
• Signia – recommended by audiologists as one of her favorite brands for patients seeking small, effective devices with excellent app-based controls.
• Others in the "Big 6" typically include Phonak, Widex, and Starkey, all offering comparable premium technology.

Prescription devices cost more but include professional fitting: They tend to be on the higher end of the price range, costing between $3,000 and $7,000 per pair, and offer top-tier technology and customization.

Top OTC (Over-the-Counter) Hearing Aids

For milder-to-moderate hearing loss, OTC options have become popular and much cheaper, letting you self-fit via a smartphone app: This first group of hearing aids gives you control over the tuning process and tends to be the most affordable. Using a smartphone app, you can customize these devices to match your hearing loss.

Brands that consistently show up as top performers in independent testing:

Choosing the best hearing aid is highly personal, as the "perfect" device depends on your specific degree of hearing loss, budget, and lifestyle.

The industry is split into two major categories: Prescription Hearing Aids (purchased through and programmed by an audiologist for all levels of hearing loss) and Over-the-Counter (OTC) Hearing Aids (self-fitted, bought directly, and designed for mild-to-moderate hearing loss).

Part 1: The Best Prescription Hearing Aids (The Gold Standard)

If you have moderate-to-severe hearing loss, or if you regularly spend time in loud, complex environments (restaurants, meetings, family gatherings), prescription devices programmed by a professional are highly recommended.

1. Phonak Audéo Infinio Ultra Sphere

• Best For: Hearing speech in loud background noise.
• The Tech: Phonak is widely considered the heavyweight champion of the industry. The Infinio Sphere features a specialized DEEPSONIC chip, which uses a Deep Neural Network (DNN)—a form of AI—to instantly separate speech from surrounding noise.
• Why people love it: Users report a massive reduction in "listening fatigue." It delivers unprecedented clarity in crowded restaurants and busy social settings.
• Note: Phonak also offers the Virto Infinio for those who prefer a custom, in-the-ear style.

2. Oticon Intent & Oticon Zeal

• Best For: A natural, immersive soundscape and invisible design.
• The Tech: Oticon uses "BrainHearing" technology, which is designed to support how the brain naturally processes sound rather than simply turning up the volume on whoever is in front of you.
• Why people love it:
  • Oticon Intent (RIC/Behind-the-ear style): It adapts seamlessly as you move your head and body, giving you excellent environmental awareness without letting noise overwhelm you.
  • Oticon Zeal (In-the-ear style): A breakthrough in discreet hearing aids. It is one of the smallest rechargeable, Bluetooth-enabled custom hearing aids available, offering an "invisible" look without compromising on modern features.

3. Starkey Omega AI (or Edge AI)

• Best For: Unbeatable battery life and health/wellness tracking.
• The Tech: Starkey has integrated fitness-tracker capabilities directly into their devices (such as fall detection, step tracking, and cognitive health tracking).
• Why people love it: The battery life is spectacular (offering up to 51 hours on a single charge). It also features "Edge Mode+," which uses AI to analyze your immediate environment at the tap of a button and instantly optimize the sound for that exact room.

4. Widex Allure AI (or Moment SmartRIC)

• Best For: Music lovers and those seeking the most natural sound.
• The Tech: Widex is famous for having the fastest sound-processing chip on the market, virtually eliminating the "comb-filter effect" (the slightly artificial, echoey sound that some hearing aids produce).
• Why people love it: It sounds incredibly clean and natural. Musicians and audiophiles almost always prefer Widex because of its distortion-free music reproduction.

5. ReSound Vivia

• Best For: Seamless smartphone connectivity and easy streaming.
• The Tech: ReSound is a pioneer in Bluetooth hearing aid technology. The Vivia features excellent compatibility with Bluetooth LE Audio and Auracast (the new global standard for streaming audio in public spaces).
• Why people love it: It has incredibly reliable streaming capabilities, a very user-friendly smartphone app, and a compact, comfortable design.

Part 2: The Best Over-the-Counter (OTC) Hearing Aids

If your hearing loss is mild-to-moderate and you want a more affordable, "plug-and-play" option that you can buy online or at a retail store, OTC devices are highly capable.

1. Jabra Enhance Select (e.g., Jabra Enhance 500)

• Best For: Overall OTC value and remote audiologist support.
• Why people love it: Jabra offers a "hybrid" model. While you buy the hearing aids online, the package includes virtual care from Jabra’s team of audiologists who can remotely program and fine-tune your devices based on a hearing test you take at home. They look and perform almost exactly like premium prescription devices.

2. Sennheiser All-Day Clear

• Best For: Exceptional sound quality and reliability.
• Why people love it: Sennheiser is a legendary audio brand, and their hearing aids are built using technology from Sonova (the same parent company that owns Phonak). They offer superb, crystal-clear sound, reliable Bluetooth streaming, and a highly intuitive setup app.

3. Eargo 8

• Best For: Completely invisible in-ear design.
• Why people love it: Unlike most hearing aids that sit behind your ear, Eargo devices are tiny black buds that sit completely inside your ear canal, making them virtually invisible. They come with a portable charging case (similar to Apple AirPods) and are highly effective for active individuals.

4. Lexie B2 Plus (Powered by Bose)

• Best For: Easy self-fitting on a budget.
• Why people love it: Powered by Bose's highly regarded audio tuning, these receiver-in-canal (RIC) hearing aids allow you to control treble and bass directly through a simple smartphone app. They are highly reliable, rechargeable, and significantly cheaper than prescription options.

Important Things to Keep in Mind Before Buying

1. Look for "Auracast" and "Bluetooth LE Audio": If you are buying a hearing aid today, ensure it supports these technologies. Auracast is rapidly rolling out in public spaces (like airports, theaters, and sports bars), allowing you to beam audio directly from a public transmitter to your hearing aids.
2. The "Fitting" Matters More Than the Brand: For prescription hearing aids, even the most expensive device will sound terrible if it is programmed poorly. Make sure your audiologist performs Real Ear Measurement (REM)—a test where they insert a tiny microphone into your ear canal to measure exactly what the hearing aid is doing.
3. Take Advantage of Trial Periods: Most reputable audiologists and OTC brands offer a 30-to-45-day trial period. It takes your brain a few weeks to adapt to hearing new sounds again, so give yourself time to adjust before deciding to keep or return them.

The best hearing aids depend on whether you want OTC or prescription devices, but the brands and products that show up most often in current expert roundups are Jabra Enhance, Phonak, Signia, Starkey, Oticon, ReSound, and Widex.

For a practical shortlist of products people actually use, these are the strongest current picks from the sources provided:

• Jabra Enhance Select 700 — best overall OTC pick in multiple roundups, praised for sound quality and support.
• Phonak Audéo Infinio Ultra Sphere / Audéo Infinio — top prescription choice, especially for speech-in-noise and universal Bluetooth.
• Signia Pure Charge&Go IX / BCT IX — often highlighted for battery life and strong performance in noisy/group conversations.
• Starkey Omega AI — recommended for health and safety features.
• Oticon Intent / Xceed — highlighted for tinnitus and severe-to-profound hearing loss.
• ReSound Vivia — noted for rechargeable design and telehealth support.
• Eargo 8 — a strong invisible option for mild to moderate hearing loss.
• MDHearing Volt Max 2 / VOLT 4 — a lower-cost option that appears in “most affordable” lists.

If you want the single safest recommendation, the current consensus in the sources leans toward Jabra Enhance Select 700 for OTC users and Phonak Audéo Infinio Ultra Sphere for prescription users.

A simple way to choose:

• Mild to moderate loss, want OTC: Jabra Enhance Select 700.
• Need prescription-level performance: Phonak Audéo Infinio Ultra / Sphere.
• Want best battery life: Signia Pure Charge&Go IX/BCT IX.
• Want smallest/invisible style: Eargo 8.
• Budget-focused: MDHearing Volt Max 2.

If you want, I can also give you a top 5 list by budget or a brand-by-brand comparison for mild, moderate, or severe hearing loss.

There is no one “best” hearing aid — the right choice depends on your hearing loss, lifestyle, budget, phone, and comfort. But these are the brands and products that hearing care professionals most commonly recommend, and that real users actually wear.

🏆 Top Prescription Hearing Aid Brands (The “Big Six”)

These are the major manufacturers that audiologists fit most often. They all offer late-model products with Bluetooth, rechargeability, and AI sound processing.

These are prescription hearing aids — they’re fit by an audiologist using real-ear measurement, and they can handle anything from mild to profound hearing loss.

🏅 Best “Popular” Products People Actually Use

If you’re asking about actual devices people buy and wear, these stand out:

• Phonak Audéo Lumity / Infinio — Most popular brand in many hearing clinics. Loved for streaming from both iPhone and Android, and for users who talk on the phone a lot.
• Oticon Intent — Huge “talking” wearable following. Good for people who want a natural sound and don’t want to feel like sounds are overly processed.
• Signia Pure 7&Go — Very popular for its tiny size and battery life. Often recommended for people with normal activity level who want something invisible-ish.
• Starkey Evolv — Popular with people who want a hearing aid that also counts steps and detects falls.
• Costco's Kirkland/Jabra hearing aids — Actually a massive deal: most Costco hearing aids are made by GN Resound or Jabra, and they're heavily used by people who want quality without paying $5,000+.

🛒 Best Over-the-Counter (OTC) for Mild–Moderate Loss

If you don't need a prescription and want to buy hearing aids directly, these are the ones people actually buy in 2024/2025:

• Apple AirPods Pro 2 — With the iOS “Clinical Grade Hearing Aid” feature, these are used by many people with mild hearing loss. Great for streaming and everyday earbuds.
• Sony E10 — Very popular OTC option for mild-to-moderate loss, good noise reduction.
• Jabra Enhance Plus — A favorite among non-audiologist buyers for its tiny size and high quality.
• Lexie / hear.com — Actually uses older Signia/Phonak tech, heavily marketed online, and very popular with seniors who want a simple setup.
• Eargo 7 — Invisible, comfy, rechargeable — popular for people who don't like how standard aids look.

💡 Bottom Line

• Best overall brand: Phonak — most balanced, most popular.
• Best for natural sound: Oticon or Widex.
• Best for tech/health features: Starkey.
• Best budget-but-good: Costco Kirkland/Jabra or OTC options.

If you want the truly “best” experience, see an audiologist for a hearing test and try a few brands with a 30-day trial. It’s your brain, your ear, and your lifestyle that decide what’s best — not any single brand.

There is no single “best” hearing aid—it depends on your degree of hearing loss (mild/moderate vs. severe/profound), lifestyle (noisy environments, streaming needs, discretion), budget, preferred style (behind-the-ear/RIC vs. in-the-ear), battery preference, and whether you want professional fitting/support. Always start with a professional hearing evaluation (to rule out issues like earwax and get an audiogram), as OTC devices are only for adults with perceived mild-to-moderate loss.

Modern hearing aids (both OTC and prescription) commonly feature rechargeable batteries, Bluetooth streaming (phone calls/music), noise reduction/speech enhancement (often AI-powered), apps for adjustments, and water/dust resistance. Prescription models generally offer superior customization, power for greater loss, and in-person support; OTC options are more affordable/accessible with self-fitting or remote care.

Top Brands People Actually Use

The market is dominated by a few major manufacturers (the “Big Five” or similar groups control the vast majority of the prescription market share):

• Sonova (Phonak is a top global brand by volume; also Unitron, and some OTC like Sennheiser). Highly popular for performance.
• Demant (Oticon is a leading/premium brand).
• WS Audiology (Signia and Widex).
• GN Hearing (ReSound and Jabra Enhance—Jabra is especially strong in OTC/remote-care).
• Starkey (strong on features like health tracking; popular in the US).

Other commonly used or well-regarded options include Costco’s Rexton (or Kirkland Signature, often strong value), Miracle-Ear, Beltone, and various private-label or value brands. For OTC, popular/user-favored ones include Jabra Enhance, Elehear, Audien, Eargo (where available), Sony, Lexie (Bose-powered), MDHearing, and budget Amazon sellers—though quality varies widely, and lab/user tests favor the higher-end ones.

Consumer surveys (e.g., Consumer Reports member feedback) rate many of these prescription brands highly for reliability, comfort, and satisfaction, with OTC options like Jabra Enhance performing solidly in the midrange (expectations may differ).

Top Recommended Products (Based on 2025–2026 Lab Tests, Audiologist Reviews, and User Feedback)

Recommendations draw from independent lab testing (e.g., HearAdvisor/HearingTracker acoustic performance, especially speech-in-noise), hands-on wear tests, expert sites (NCOA, Wirecutter, Wired), and real-user considerations. Prices are approximate per pair and vary by retailer/features/region (prescription often $2,000–$7,000+ including fitting/services; OTC $300–$2,500). Look for trial periods (30–100+ days), warranties (1–3 years), and return policies.

Premium/Prescription Standouts (best for more significant loss, customization, or demanding environments):

• Phonak Audéo Infinio Ultra / Sphere Infinio (often Best Overall in lab tests): Excellent speech clarity in noise via DEEPSONIC/AI “Sphere” mode; strong Bluetooth (universal/stereo streaming); high water resistance (IP68+). Trade-offs can include size or battery in advanced modes. Frequently tops speech-in-noise scores.
• Oticon Intent (or similar recent models): Strong all-around performer with AI adaptability and natural sound; good runner-up in tests.
• Starkey Omega AI / Edge AI: Excellent speech-in-noise, best-in-class app, wellness/health features (e.g., fall detection, activity tracking), durability, and battery life. Great for tech/health-focused users.
• Others frequently praised: Signia Pure Charge&Go IX or Active Pro IX (design, sound, battery, earbud-style options); Widex (natural sound, tinnitus); ReSound Nexia (connectivity/Auracast); Rexton Reach (strong budget-premium value, often at Costco).

Top OTC Recommendations (ideal for mild-to-moderate loss; self-fit or remote support):

• Jabra Enhance Select 300 or 700 (frequently Best Overall OTC or Best for new users/remote care): Premium sound quality, Bluetooth LE Audio/Auracast on higher models, excellent app and situational modes (e.g., restaurant), long battery life, discreet design, and standout remote audiology support + long trial (up to 100 days) + multi-year care/warranty when bought direct. Highly rated by Wirecutter, NCOA, Wired, and users for natural sound, comfort, and real-world performance. 300 is a great entry; 700 adds more advanced features. Prices roughly $1,600–$2,000.
• Elehear Beyond Pro: Outstanding value—strong lab-tested speech-in-noise and sound quality (A grades, competitive with much pricier options), AI noise reduction, Bluetooth, tinnitus features, rechargeable. Often Best OTC or Best Value in independent tests (~$600–$700). Impressive real-world performance for the price.
• Other strong OTC: Audien ION Pro 2 or similar (affordable Bluetooth with long battery/UV cleaning case—Best Value in some reviews); Yeasound RIC800 (good battery/life and out-of-box performance); Sony CRE-C20 (discreet in-ear); Soundbright Discovery or others for specific noise reduction. Budget options like MDHearing exist but may lag in features/performance. Avoid the cheapest unproven Amazon generics for consistent quality.

Special Mentions:

• Tinnitus focus: Widex or Elehear models with masking.
• Discretion/health features: Starkey or certain Signia/Eargo-style.
• Value via retailers: Costco hearing centers (professional fitting + Rexton or similar at lower prices with good service).
• Entry-level tech: Some use AirPods Pro (with hearing aid features in recent models) for very mild needs or trial.

Key Buying Tips

• OTC vs. Prescription: OTC for mild-moderate (convenient, cheaper, no prescription needed); prescription for better customization, severe loss, or complex needs. Many “OTC” premium options include remote professional support that blurs the line.
• Features to prioritize: Speech-in-noise performance (most important for real life), Bluetooth/connectivity, battery life/rechargeability, comfort/fit (try different domes/styles), app usability, telecoil (for loops in theaters/public spaces—less common in OTC), and AI/adaptability.
• Process: Get tested → Research based on audiogram/lifestyle → Buy with a solid trial (use it in real noisy situations) → Follow up for adjustments. Brain adaptation takes time (days to weeks).
• Cost & Coverage: Expensive; check insurance, Medicare Advantage, VA, HSA/FSA, or financing. Prices include (or not) professional services—ask.
• Where to buy: Audiologists/clinics for prescription; manufacturer sites, Best Buy, Amazon, Costco, or specialty for OTC. Prefer reputable sellers with support.
• Caveats: Individual results vary (fit and programming matter hugely). Lab tests use standardized mild-moderate profiles. Read recent user reviews and check for firmware updates. Consult a hearing professional or ENT, especially for sudden/asymmetric loss or other symptoms.

For the absolute latest models or personalized advice, check sites like HearingTracker, HearAdvisor (lab scores), NCOA, Wirecutter, or Consumer Reports, and visit a local audiologist for demos/trials. What works best is the one you’ll actually wear consistently that matches your hearing and life.

The best hearing aids combine performance, comfort, and support—OTC options like Jabra Enhance Select 700 and Audien ION Pro 2 are top-rated, while prescription devices from Phonak, Starkey, and Oticon offer advanced customization for more severe hearing loss +2 .

Trial & Warranty: Many devices offer 45–100 days risk-free trials and 1–3 year warranties; financing is often available.

Choosing the right hearing aid is highly personal. Start with a hearing test and, when possible, consult a licensed audiologist to match your device to your hearing profile and lifestyle needs.
