Lexie Powered by Bose vs. Signia Silk Charge&Go IX

This rechargeable device offers iPhone and Android call streaming, a new recharging case, and an in-app hearing test for personalized sound customization.

The Signia Silk Charge&Go IX is a groundbreaking, rechargeable completely-in-canal (CIC) hearing aid designed for people with mild to moderate hearing loss. It offers up to 28 hours of battery life, instant fit with soft silicone ear tips, and wireless control via the Signia app, but lacks Bluetooth streaming and can be challenging to handle due to its small size.

Lexie B2 Plus achieved a SoundScore of 4.4/5 and a SoundGrade of A in HearAdvisor lab testing. It ranked #7 of 65 OTC Hearing Aid devices tested. The OTC Hearing Aid category average SoundScore was 3.68/5.

Signia Silk Charge&Go IX achieved a SoundScore of 3.7/5 and a SoundGrade of B in HearAdvisor lab testing. It ranked #32 of 39 Prescription Hearing Aid devices tested. The Prescription Hearing Aid category average SoundScore was 4.19/5.

Lexie claims all of their products have an IP rating of 67 which is near the maximal egress protection for hearing aids. Beyond this, I found B2 well built with a good button click feel and robust portable charging case.

Signia Silk C&G IX have an impressive build quality, featuring a top-of-the-line IP68 ingress rating, which is crucial for nearly invisible hearing aids. They also come with a durable portable charging case.

Lexie B2 has a reported battery life of 18 hours so it should last all-day for most people. It takes only 3 hours to recharge in its case which also doubles as a portable charger thanks to the internal power-bank.

Silk IX provide up to 20 hours of use per charge which is exceptional given their extremely small size. Recharging takes up to 4 hours, which is longer than some other models, but this isn't a significant drawback given their all-day battery life.

B2 does offer audio streaming though it is unfortunately limited to iOS devices. I found B2’s streamed audio quality mediocre but it is a useful feature to have for those of use using Apple products.

The phone app is one of my favorite features of B2. It is simple and visually pleasing while offering excellent personalization. Lexie has recently added an in-app hearing test making it even better.

While Silk IX hearing aids are not Bluetooth compatible, they still work with Signia's app using high-frequency coded signals. This is a valuable addition, although the communication is less stable than Bluetooth and the app offers fewer features compared to other Signia models.

B2 is a rather sleek receiver-in-canal (RIC) hearing aid. I found its comfort similar to that of prescription hearing aids and experienced no issues wearing it long-term (even with glasses).

I found Silk IX very comfortable for an instant-fit nearly invisible hearing aid. Your hearing care provider should ensure they are fitted for optimal comfort and hearing benefit.

Lexie B2 offers a sleek design similar to modern prescription hearing aids from major manufacturers. One potential downside is that it is only available in Gray, with no other color options.

Silk IX is another unique offering from Signia, featuring an instant fit design with silicone ear tips that is nearly invisible. Its extremely small and discreet design may, however, pose challenges for those with limited dexterity and or vision.

Lexie B2 Plus has a value score of 4.2/5 based on lab performance and public display price.

Signia Silk Charge&Go IX has a value score of 2.8/5 based on lab performance and public display price.

I had no issues adjusting B2 with the app or rocker switch. I found the physical buttons sufficiently large and tactile offering a good click feel when depressed.

I did not run into any issues while using Silk IX hearing aids. They are very easy to use once setup by your hearing care provider. Silk also have large color indicators making it easy to distinguish the left from the right hearing aids.

One downside to Lexie B2 is that you are limited to phone or email based technical support. Fortunately, B2 and their phone app are fairly user-friendly and you will likely not need regular assistance.

You should receive quality hearing care and support from your provider. The Signia App should further enhance your experience with AI help and remote assistance should your provider offer telehealth services.
