Compare between Earlens and other vendors

Unlike acoustic hearing aids that rely on speakers to amplify sound through the ear canal, Earlens uses a custom tympanic lens that sits on the tympanic membrane (eardrum) and directly drives it using an inductive hearing aid system. This allows the device to bypass many limitations of traditional hearing aid technology, offering extended audible bandwidth up to 10 kHz. That means high-frequency consonant sounds are easier to hear, especially in background noise.

Earlens offers Made for iPhone streaming, allowing Earlens patients to stream calls, music, and adjust settings through the Earlens Control app. It does not support Android phones, which means users of Apple devices benefit most from its wireless features.

Yes. Earlens provides a trial period that typically ranges from 30 to 75 days, depending on the provider. During this time, users can evaluate whether the system improves amplification and audibility, especially for those with severe sensorineural hearing loss. The trial also helps determine candidacy, ensuring the user’s middle ear system and cochlea can benefit from the unique direct-drive approach.

The Earlens system includes a rechargeable processor that docks into the Earlens charger overnight. A full charge typically lasts between 16 and 24 hours. Since the processor powers the tympanic lens rather than a speaker, it efficiently supports extended bandwidth and consistent dB gain without relying on disposable batteries.

The tympanic lens is not permanent but stays in place during regular daily activities. Only an ENT physician can place or remove it. Because it sits on the tympanic membrane, proper care is essential. Most Earlens patients quickly adjust to its presence. Routine follow-ups ensure the middle ear remains healthy, and the lens continues to provide excellent sound quality and improved access to high frequencies.
