HearAdvisor SoundScore

Link
4.0ABOVE AVERAGE

The Eargo Link achieved a SoundGrade of B and ranked in the top 23% in the OTC Hearing Aid category. With a SoundScore of 4.00/5, it performs above the category average of 3.43, demonstrating competitive overall sound quality in HearAdvisor's standardized testing protocol.

Zeal
4.3ABOVE AVERAGE

Oticon Zeal achieved a SoundScore of 4.26/5 in HearAdvisor lab testing. The Prescription Hearing Aid category average SoundScore was 3.91/5.

Build Quality

Link
3.8BELOW AVERAGE

The Eargo Link seem to be a slight regression in build quality and have an IP54 rating, which is lower than other Eargo models. This means they are not water-proof and will require extra care to continue working well long term.

Zeal
5.0EXCELLENT

Zeal offer excellent moisture and dust protection with an ingress rating of IP68. Both the hearing aids and case are well build and ready for daily use.

Battery

Link
2.9BELOW AVERAGE

I liked the portable charging case and magnetic locks. However, the 9 hour rechargeable battery life means they will not last all day and will be better suited for situational use rather than all-day hearing help.

Zeal
4.2ABOVE AVERAGE

With a battery life of up to 20 hours, Zeal should last you all day.

Bluetooth

Link
5.0EXCELLENT

I was impressed with Eargo Link's audio quality for both streaming and hands-free calls. The Bluetooth 5.3 compatibility is a significant upgrade from Eargo's other products that don't support streaming.

Zeal
5.0EXCELLENT

I found Zeal to offer easy and stable wireless connection. Their audio quality while streaming music, and during hands-free calling, was good and comparable to other prescription hearing aids.

App Features

Zeal
5.0EXCELLENT

I found the Companion app easy to navigate and use. Other prescription hearing aid companies offer more in-depth health features, but there is still plenty of opportunity to customize settings from your mobile device. The HearingFitness component is also a nice feature for those who like to actively track their progress.

Comfort

Link
4.0AVERAGE

Link were moderately comfortable in my ears and feel like typical wireless earbuds. I was able to switch through the included ear tips to find the right fit for both comfort and sound quality.

Zeal
4.8EXCELLENT

Oticon Zeal were extremely comfortable and lightweight in my ears. In general, hearing care providers can make numerous physical changes to prescription hearing aids like Zeal to improve comfort.

Design

Link
4.5EXCELLENT

With their modern earbud-like appearance, Link is definitely more bold than other Eargo models. While I like the earbud look, you will have to decide whether you prefer a more discrete hearing aid option.

Zeal
5.0EXCELLENT

Zeal are sleek, easy to use, in-the-ear prescription hearing aids. They are nearly invisible in the ear which is extremely impressive given their battery life and wireless capabilities.

Value

Link
3.6AVERAGE

The Eargo Link offers solid performance for its $799 price point, though several competitors in the same price range achieve higher scores.

Zeal
3.2BELOW AVERAGE

Oticon Zeal has a value score of 3.2/5 based on lab performance and public display price.

Handling

Link
3.5BELOW AVERAGE

Instead of typical multi-function buttons, Link uses touch sensors. These worked well, and more reliably than other products I've tested, though the app would be a nice addition for manual controls.

Zeal
5.0EXCELLENT

Zeal are easy to use and adjust with the Oticon Companion app. I had no issues making adjustments while testing them.

Pro Support

Link
1.0BELOW AVERAGE

Eargo is one of the first direct to consumer hearing aids, but support is unfortunately limited to to their Client Care team and personal hearing professionals. While Eargo claims they work alongside audiologists, it is not the same as direct professional hearing care.

Zeal
5.0EXCELLENT

Prescription hearing aids like Zeal are fit by hearing care providers so you should receive quality care. The Oticon Companion app also opens the possibility for remote programming and virtual follow-up appointments.

Clear DynamicsClear DynamicsClear Dynamics expands the input dynamic range, processing input sounds up to 113 dB SPL, to provide better sound quality without distortion and artifact at loud input levels, while still keeping the sound quality of soft input levels intact. Clear Dynamics has an operating range from 5 to 113 dB SPL. With speech cues preserved at high input levels, users enjoy a better listening experience without distortion even in loud environments. Clear Dynamics is especially valuable for users when listening to music or in conversations in busy, dynamic environments, where peaks can often be louder than the available input dynamic range.
Feedback SuppressionFeedback SuppressionIf any sound amplified by the hearing aid escapes the ear canal, it may reach the hearing aid’s own microphone and cause a harsh whistling noise. Some hearing aids are able to recognize when this feedback occurs and reduce or eliminate it.
