Overview

Signia Silk has long been one of the most respected invisible hearing aids on the market and was famously worn by Queen Elizabeth II. In our review, Silk stands out as the smallest rechargeable, prescription-programmed hearing aid currently available. The device is invisible in most ears and delivers reliable all-day battery life, making it a rare combination of discretion, performance, and convenience.

Background

Signia Silk is a compact, fully programmable in-ear hearing aid with a strong set of modern features, including wireless controls through the Signia app, remote programming after the initial clinic visit, and intelligent sound processing designed to manage background noise.

Silk originally set itself apart by using Signia’s proprietary Click Sleeves, which allow the hearing aids to fit securely in the ear canal without requiring custom ear impressions. Most invisible-style hearing aids require a custom mold, which adds cost and wait time. Signia’s ready-to-wear approach significantly shortens the process and lowers barriers to entry.

Most recently, Signia released a full redesign under the IX platform. Silk Charge&Go IX introduces a next-generation operating system and, for the first time, a rechargeable battery in this ultra-small form factor.

What Stands Out

Form Factor

Signia Silk is among the best invisible hearing aids available today. The devices sit entirely inside the ear canal and are typically only visible when someone looks directly into the ear.

Advanced Technology

Signia uses dual processing chips to separate speech from background noise more effectively. This additional processing power also supports advanced beamforming, helping users follow conversations when multiple speakers are present.

One standout feature is Own Voice Processing (OVP), which recognizes and reduces amplification of the wearer’s own voice. This adjustment dramatically improves comfort, as many users find over-amplified self-voice to be one of the biggest drawbacks of in-ear hearing aids.

Overall, Signia Silk offers some of the strongest sound processing and noise management in the invisible hearing aid category, without requiring custom earmolds.

Rechargeable Batteries

Silk Charge&Go IX delivers up to 28 hours of use on a single charge, an impressive achievement given its size and one of its most meaningful upgrades.

Our Take

If you are looking for an invisible, in-ear hearing aid with rechargeable batteries, Signia Silk is in rare company. Eargo is the only other invisible option offering rechargeability, though it is limited to OTC programming. For users who prioritize invisibility, rechargeability, and advanced sound processing without custom molds, Signia Silk remains one of the strongest options on the market.

Pros 👍
  • Full-featured, premium hearing aids
  • Includes an in-person hearing test at a local clinic
  • Smallest prescription devices with rechargeable batteries 
  • It does not require a custom earmold

Cons 👎
  • More expensive than OTC options
  • No Bluetooth streaming is available 
  • It can be slightly less comfortable than RIC or custom-mold options

Soundly Scorecard

Hearing Loss Level 🔊
Mild - Severe
  • Signia Silk hearing aids are appropriate for mild to severe hearing loss.
  • Silk devices are ready to wear devices, which are not custom made for your ear; this may create feedback for more severe hearing losses.
  • If you have profound hearing loss, you are a better fit for ultra-powered BTE hearing aids.
Care Type 🏥
Prescription
  • Signia hearing aids are prescription devices fitted and programmed by a Hearing Care Professional (HCP).
  • Unlike other in-the-ear style devices, Signia Silk does not require a custom-earmold. Instead, the device comes with a variety of Click Sleeves that fit a wide range of ear sizes.
  • After an initial fitting, you can connect with your HCP remotely through the Signia app for fine-tuning and program adjustment.
Sound Quality 🔊
Strong in Background Noise
  • Signia uses a unique multiple beam-forming technique with its Integrated Xperience™ technology that helps isolate background noise and boost speech clarity.
  • Signia's Own Voice Processing (OVP) helps take the edge off of that uncomfortable sound quality of the user's own voice that many patients experience when adjusting to hearing aids.
