About Soundly

Soundly is an independently owned hearing health research tool. Our reviews are conducted by hearing aid wearers and audiologists. We physically review the leading hearing aids on the market for sound quality, comfort, durability, and more. Our review process starts with hands-on unboxing and days, weeks, or months of wear. We also record live sound demos using a calibrated binaural microphone (read more here). We experiment with backend fitting software for prescription products and use test box measures to measure prescriptive accuracy and flexibility. Our work is funded through reader support. When you buy through our links, we may earn a commission. Read more about our story here.

Signia Silk was the hearing aid choice of the late Queen Elizabeth and has been one of the top invisible hearing aids on the market for years. In October 2023, Signia Silk became the market's smallest rechargeable, prescription-programmed hearing aid.

Keep scrolling for our full review, Soundly Scorecard, and notes on pricing and process.


Signia Silk is a tiny, fully customizable hearing aid with a robust set of technologies, including wireless controls via the Signia App, remote programming after your first office visit, and intelligent sound algorithms that sort out background noise.  

Signia Silk originally made a name for itself by using what they call Click Sleeves to match the size of your ear canal and make their hearing aids ready to wear. The majority of invisible-style hearing aids require a custom ear imprint. Signia's approach cuts down on prices and wait times.

Now, Signia is back with a complete renovation of their popular Signia Silk. The new Silk Charge&Go IX features a brand-new operating system and, most notably, a rechargeable battery.

What Makes Signia Silk Special

Form Factor

Signia Silk is among the best invisible hearing aids on the market. The devices sit entirely in the ear canal and are only visible to those who look straight inside your ear.

Advanced Technology

Signia uses dual processing chips inside their devices to separate speech from noise. That additional power also creates the foundation for Signia's 2023 beam-forming update for multiple speakers.

One of our favorite features inside Signia Pure Charge&Go IX hearing aids is Own Voice Processing (OVP). OVP records your voice and actively reduces its level of amplification. This slight adjustment significantly impacts comfort - many wearers don't want to hear themselves booming through their hearing aids.

The bottom line is that Signia Silk has the best hearing algorithms and sound management technology in the category.

Rechargeable Batteries

Now for the big news. Signia Silk is the smallest prescription hearing aid with rechargeable batteries. Each set of Silk Charge&Go IX hearing aids comes with a sleek little charging unit and the ability to stay connected all day.

Our Take

If you are on the market for in-the-ear hearing aids and want rechargeable batteries, Signia Silk is in rare company. Eargo (OTC disruptor) is the only other invisible option with rechargeable batteries. Some customers note that custom-molded devices like Starkey Genesis or Oticon Own are a bit more comfortable for all-day wear. Still, those devices require disposable batteries at comparable sizes.

Pros 👍
  • Full-featured, premium hearing aids
  • More affordable than custom-molded devices
  • Smallest prescription devices with rechargeable batteries
  • It does not require a custom earmold
Cons 👎
  • More expensive than OTC competitors
  • No Bluetooth streaming is available
  • It can be slightly less comfortable than RIC or custom-mold options
