Linner stands for a life well-heard. Linner, in the Audiology business since 2016, is differentiated from the rest of the OTC Hearing Aid market primarily through 3 main pillars: their intelligent, audio-optimized hardware, their interactive software which allows one to customize for their specific hearing needs, and their Audiologist-supported customer service, who can help customers optimize their hearing experience. Experience enhanced clarity and speech comprehension with the state-of-the-art 16-channel Digital Sound Processor, noise cancelation and active feedback control, plus 3 unique hearing modes and selectable volume levels, based on where you are and what you are doing at any given time. IP4 Water & Sweatproof (do not submerge) and a whopping 20-hour battery life, because life doesn't stop for a battery recharge. All that in a highly discreet receiver-in-the-ear package, so others will be none the wiser. Hearing life again has never been simpler than with Linner Mercury.
