Starkey · Custom invisible and in-canal
Starkey Signature Series
Nothing is smaller. Nothing sounds better.

About the Signature Series
Signature Series is Starkey's custom family, and it exists for one reason: many people want to hear well without anyone knowing they are wearing anything. Each shell is built individually from an impression of your own ear, taken here at the centre, so the device sits deep and comfortably in the canal where it is very difficult to see.
Because the microphone sits inside the ear rather than behind it, the outer ear does part of the work it was designed to do. Sound is collected the natural way, which helps with knowing where a voice is coming from and makes telephone use straightforward. Starkey's Neuro Sound Technology then processes that signal to keep speech clear and comfortable rather than sharp and tinny.
The completely-in-canal rechargeable model is the headline device: the smallest custom rechargeable hearing aid made, waterproof to one metre, with up to thirty-eight hours of use from a single charge. For coastal humidity and long days away from a power point, that combination matters.
Technology
What this device does
Handcrafted to your ear
We take a silicone impression of each ear at the centre and Starkey builds the shell to that exact geometry, so the fit is secure without pressure points and the seal stays consistent through the day.
Virtually invisible in the canal
The invisible-in-canal and completely-in-canal styles sit far enough inside the ear that most people never notice them, which removes the single biggest reason patients delay treatment.
Neuro Sound Technology
Starkey's processing is modelled on how the auditory system handles sound, aiming for transparent, true-to-life listening rather than simple amplification.
Rechargeable and waterproof
The rechargeable model is waterproof up to one metre and delivers up to thirty-eight hours per charge, so there are no tiny batteries to change and no anxiety about sweat or rain.
