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.

Build Quality

Enhance Select 700
5.0EXCELLENT

Jabra hearing aids share technology from GN Resound and generally have fantastic build quality. Select 700 is no exception with an ingress rating of IP68 and the standard robust portable charging case.

Silk Charge&Go IX
4.7EXCELLENT

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.

Battery

Enhance Select 700
4.0AVERAGE

Jabra 700 offer full-day 24 hour battery life. The case also holds enough power for 3 addition charges which is plenty for a weekend excursion.

Silk Charge&Go IX
4.4ABOVE AVERAGE

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.

Bluetooth

4.5EXCELLENT

The Jabra Enhance App mirrors the useful features available in Resounds prescription hearing aid app. I found it to offer plenty of options to personalize audio quality beyond the custom programming.

Silk Charge&Go IX
3.4BELOW AVERAGE

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.

Comfort

Enhance Select 700
5.0EXCELLENT

Jabra Enhance 700 are very comfortable given their shockingly small and lightweight design. The button are also larger than many OTC products making setting changes easier.

Silk Charge&Go IX
4.5EXCELLENT

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.

Design

Enhance Select 700
5.0EXCELLENT

Jabra has done a nice job redesigning prescription technology for the direct-to-consumer market. Select 700 shares the same shockingly discrete size as the previous Select 500 model.

Silk Charge&Go IX
5.0EXCELLENT

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.

Value

Handling

Enhance Select 700

I found Enhance 700 easy to use, though receiver-in-canal devices might take a bit of practice. Pro support can assist, and the easy charging case makes on-the-go charging a breeze.

Silk Charge&Go IX
4.0AVERAGE

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.

Pro Support

Enhance Select 700
3.0ABOVE AVERAGE

Jabra has arguably the best pro support offering among OTC devices. They provide 3 years of telehealth audiologic services including remote programming and video appointments. While I'd prefer in-person appointments, Jabra continues to bridge the gap given the limitations of remote care.

Silk Charge&Go IX
4.0ABOVE AVERAGE

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.

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.
Binaural Directionality™ IIIBinaural Directionality™ IIIBinaural Directionality III provides the ultimate balance for supporting natural hearing: a signal-to-noise ratio improvement similar to bilateral directional microphones and a significant benefit in ease of listening compared to other directional microphone strategies.Synchronized SoftSwitching™Synchronized SoftSwitching™SoftSwitching (synchronized between ears) uses sound level and speech detection algorithms to decide when directionality is likely to be advantageous in a certain listening environment. It also offers the same four selections of MultiScope beamwidth settings: the default AutoScope, Narrow, Medium and Wide. The SoftSwitching mode differs from MultiScope Adaptive Directionality in that it uses slower transitions between directional settings and the omnidirectional setting, which is sometimes more comfortable and preferable among certain hearing aid users.
Binaural OneMic directionalityBinaural OneMic directionalityEach CIC receives the sound and information not only from its own microphone but also from the microphone of the other hearing aid. This creates a virtual four-microphone network, allowing the pair of hearing aids to create a directional beam. In addition, the natural pinnae effect of the outer ear supports this directionality and makes the listening experience even more natural.

Wind Noise ReductionWind Noise ReductionAs wind blows against the microphones of hearing aids, unpleasant noise may be generated. Some hearing aids have the ability to recognize this wind noise and reduce its level. Such reductions may also affect the audibility of desired sounds, like speech.
Wind Guard: On/OffWind GuardWhen no wind noise is found, the hearing aid constantly updates and stores the sound input levels in each Warp band. Then, when wind is present, WindGuard calculates the amount of gain reduction needed to return to the stored level of the specific bands affected by wind noise.
