Swedish Bellman & Symfon Maxi Digital Personal Amplifier is a revolutionary communication aid that uses digital state-of-the-art technology to bring out speech and music in difficult listening situations.

Outstanding sound

Maxi delivers the clear and crisp digital sound that you deserve. It fully exploits the advantages of digital technology to clarify speech and reduce annoying background noise and feedback – all to give you an outstanding sound quality. Thanks to a unique microphone suspension, Maxi's ultra-sensitive microphone is effectively protected from handling noise. This guarantees hours of comfortable and noise-free listening.

Easy to handle

Bellman Audio Maxi has been designed with simplicity and usability in mind. All common functions can be accessed using a single push on a button and there are no complicated menus to get lost in. Unparalleled ergonomics combined with high contrast coloring, large tactile buttons and soft grip materials, makes Maxi the ideal companion for hearing impaired individuals who demand flexibility, quality and ease of use.


Bellman Audio Maxi can be used in a variety of applications with optional add-on accessories. The Maxi Neckloop (sold separately) connects your hands free wireless device or MP3 player with the Maxi for use with your t-coil hearing aid. For TV listening, simply attach the Maxi External TV Microphone accessory (sold separately) to your TV's speaker. With the Maxi Cable Kit accessory (sold separately), you can enjoy high quality stereo sound.
