Signia Silk Nx

The hearing aid brand Signia is part of the Sivantos Group. Signia utilizes advanced technology, such as the binax system, for its debut model, the primax. Shown in clinical trials to reduce listening effort and improve cognitive ability, the primax platform subsequently created the foundation for Signa’s Silk Nx hearing aid range.

The Signia Silk Nx is one of the world’s smallest devices that becomes invisible when worn in the ear. The device is a completely-in-canal (CIC) hearing aid that takes an impression of the ear to produce a hand-made or 3D printed hearing aid shell. The electronics and hearing aid components are contained within the shell. With the Silk Nx, there is no custom-fitting process as soft-silicone ‘Click Sleeves’ are used which mold to the contours of your ear canal for immediate fitting into ear canals of all shapes and sizes. The Silk Nx by Signia is available in three technology levels to suit different hearing needs, tech preferences and budgets:

  • Silk Nx 3Nx: basic level technology
  • Silk Nx 5Nx: mid-level technology
  • Silk Nx 7Nx: top of the range

Signia Silk Nx hearing aid - price range and features

The Signia Silk Nx is 20% smaller than the Signia Silk primax providing users with ultimate discretion. It features Ultra HD e2e, enabling the hearing aids to communicate audio and other data across both hearing aids to fully optimize the user’s hearing experience, even in the noisiest of environments. Signia Silk Nx hearing aids are the world’s first to be able to process the user’s voice separately from all other sounds to make hearing your voice much more comfortable and natural. The only completely-in-canal (CIC) CROS (Contra-lateral Routing of Signal) device for people with hearing loss in one ear that cannot be assisted by a device, the Silk Nx can be used with compatible smartphones thanks to their Bluetooth streaming capability.

The Signia Silk Nx price varies depending on where you purchase the product aids. However, be ready to pay between $1,400 and $3,200, placing the cost of the Silk Nx in the mid-tier range.

  • miniPocket: Keyring-sized remote control app for discreetly and conveniently controlling your hearing aids without needing to connect to a smartphone or large remote control
  • Click Sleeves: Provides improved feedback stability, wearing comfort and retention together with instant fitting. Disposable soft silicone Click Sleeves provide comfort and retention of the hearing aid in the ear. Available in close and vented options
