Envoy Medical Corporation is a US-based medical device manufacturer specializing in fully implanted active middle ear implants (FI-AMEI) for patients with hearing loss. The company's flagship product, the Esteem®, is a surgically implanted device designed for patients with sensorineural, conductive, or mixed hearing loss who may not benefit from traditional hearing aids or who seek an invisible, fully implantable alternative.

The company positions itself as "America's Hearing Implant Company" and provides comprehensive patient support including fitting, programming, and customer service.
