The Batphones by Matthias Ries.
"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.
