Batphones / hearing aid

Batphones are designed to increase the hearing capability in frontal situations
such as watching TV or listening to a speech in the back rows.

Therfor, the ears are being extended to focus onto the speaker(s) and capture
a wider amount of sound waves.
Being low-tech, that is consisting of just one piece of injection moulded plastic,
Batphones are also low-cost and can be distributed as an advertising gift during
a speech or a congress for example.
