Signia Silk CROS: The Invisible Completely-in-Canal (CIC) Solution for Single-Sided Deafness

For patients diagnosed with Single-Sided Deafness (SSD), conventional Behind-The-Ear (BTE) or Receiver-In-Canal (RIC) CROS units have been the standard prescription for years. However, many patients hesitate to proceed. Wearers who use eyeglasses, sunglasses, surgical masks, or women wearing headscarves (hijab) often find having devices resting behind both ears physically uncomfortable or cosmetically noticeable.

Enter the Signia Silk CROS: the world's first and only Completely-in-Canal (CIC) ready-to-wear CROS hearing system. It delivers complete cross-head sound transmission while resting completely hidden inside the ear canal.

1. What Makes Signia Silk CROS Revolutionary?

Until recently, fitting a CROS system required hardware behind the ear because beaming audio across the skull requires specialized antennas. Signia achieved an engineering breakthrough with its proprietary Ultra HD e2e binaural wireless technology, packaging the microphone, wireless transceiver, and digital processing chip into a tiny instrument that fits entirely into the canal.

• Zero Behind-The-Ear Hardware: Nothing touches your outer ear or sits behind your earlobes. You can wear eyeglasses, sunglasses, and head coverings with total freedom.
• Completely Invisible: The faceplate is tinted deep matte black to mimic the natural dark shadow of the ear canal, making it virtually imperceptible to people standing right beside you.
• Natural Pinna Acoustics: Because the microphone sits inside the ear canal rather than behind the ear, it naturally utilizes your outer ear's anatomy (pinna) to capture sound just as biology intended.

2. Instant Fit with Soft-Silicone Click Sleeves™

Historically, completely-in-canal devices required taking uncomfortable silicone ear impressions and waiting weeks for custom acrylic shells to be fabricated from overseas laboratories.

Signia Silk CROS eliminates the wait using patented Click Sleeves™:

Crafted from super-soft, skin-friendly medical silicone with an anti-slip texture, Click Sleeves flex to mirror the individual curves of your canal. During your appointment at Ensound, our audiologist selects the exact size, clicks it onto the Silk CROS unit, and you walk out hearing with it immediately.

3. How Silk CROS Pairs with Your Better Ear

The Signia Silk CROS unit sits in your unaidable ear and acts as an acoustic radar, capturing speech and sound. It wirelessly streams that audio continuously to a compatible Signia Silk hearing aid in your functional ear. If your better ear has normal hearing, the receiver delivers an open, natural sound. If your better ear has mild hearing loss (BiCROS setup), it amplifies both sides cleanly.

4. Discreet Smartphone Control

You can adjust volume balance and program modes discreetly from your iPhone or Android smartphone using the Signia App. The app transmits high-frequency acoustic control signals that require no bulky external remote control.
