Build Quality

7
4.0BELOW AVERAGE

Eargo 7 hearing aids appear to be well build with an IPX7 rating, making them sufficiently durable against moisture which is important given their deep ear canal placement. The portable charging case is also a nice addition and should protect Eargo well when not in use.

Styletto AX
5.0EXCELLENT

Signia Styletto AX have an impressive build quality, featuring a top-of-the-line IP68 ingress rating. They also come with a robust portable charging case.

Battery

7
3.3BELOW AVERAGE

Eargo are extremely small making their 16 hour rechargeable battery life impressive. The case offers additional on-the-go power and I found the magnetic charging bays a nice easy to use addition.

Styletto AX
4.0AVERAGE

Styletto AX hearing aids provide up to 16 hours of use per charge, longer without regular streaming. Recharging takes up to 4 hours, which is longer than some other models, but this isn't a significant drawback given their nearly all-day battery capabilities.

Styletto AX are Bluetooth compatible with both iOS and Android devices, allowing for audio streaming and hands-free calling.

App Features

7
3.5BELOW AVERAGE

I found Eargo's app to be packed full of useful features like the Sound Match hearing assessment and automatic noise reduction controls. You have plenty of options for personalization though adjustments are not always reliable as Eargo relies on phone speaker commands instead of Bluetooth.

Styletto AX
5.0EXCELLENT

Signia's hearing aid app stands out with its user-friendly interface and modern, appealing design. It includes practical features like the ability to control the focus of your hearing aids and a mask mode to enhance speech clarity. Additionally, the app offers wellness features, utilizing hearing aid motion sensors for activity tracking.

Comfort

7
3.9BELOW AVERAGE

Comfort will vary by individuals depending on your tolerance to a deeper fitting hearing aid. Overall, I found them moderately comfortable through they can cause a tickling ear sensation due to their fit.

Styletto AX
5.0EXCELLENT

I found Styletto AX to be very comfortable thanks to their slim and ergonomic design. Your hearing care provider should ensure they are fitted for optimal comfort and hearing benefit.

Design

7
4.8EXCELLENT

Eargo's instant-fit, completely-in-the-canal, style is unique discrete. If you are interested in a nearly-invisible OTC hearing aid you will love their design.

Styletto AX
4.8EXCELLENT

Styletto AX features a unique, slim design and is available in a variety of colors, from discreet to bold. However, its longer body may be less desirable for those with smaller ears.

Value

Eargo 7 has a value score of 2.4/5 based on lab performance and public display price.

Styletto AX
3.3BELOW AVERAGE

Signia Styletto AX has a value score of 3.2/5 based on lab performance and public display price.

Handling

7
3.0BELOW AVERAGE

Handling can be challenging with Eargo 7 due to the small size and reliance on tap controls. Furthermore, Eargo relies on acoustic indicators for wireless communication, which is less reliable than Bluetooth and caused me several problems.

Styletto AX
4.6EXCELLENT

I did not run into any issues while using Styletto AX hearing aids. They are very easy to use once setup by your hearing care provider. First-time users may need some practice to get accustomed to inserting the receiver-in-ear style properly.

Pro Support

7
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.

Styletto AX
5.0EXCELLENT

You should receive quality hearing care and support from your provider. The Signia App should enhance your experience with AI assistance and user-friendly virtual appointments, given your provider offers telehealth services.

Adjustment BandsAdjustment BandsThese are frequency-divided sections that can be adjusted in a hearing aid in order to amplify sounds. Although there are rarely more than 10 frequencies measured in a hearing assessment, having more bands that can be adjusted may allow for improved speech understanding and user comfort.

Adjustment SynchronizationAdjustment SynchronizationThis feature allows for a more pleasant listening experience by ensuring that both hearing aids process sound the same way. If one hearing aid changes its processing in response to noise or speech, it will send a wireless signal to the other hearing aid so both process sound in the same way.

TwinPhoneTwinPhoneTwinPhone is the optimal solution for these wearers. It is automatically activated by a magnetic signal, so the wearer hears the caller in both ears for better understanding.
DirectionalityDirectionalityDepending on the types and number of microphones a hearing aid has, the hearing aid may be able to boost sounds from specific directions (by reducing sounds from other directions). This can be helpful to focus on a speaker directly in front of the hearing aid user, as well as to give the user information about where different sounds are coming from.
