Bumper Sound is a flat rubber-coated earphone cable that wraps around one’s mobile phone to protect it from bumps and knocks.

Many mobile phone users attach a case to their phone in order to prevent scratches and protect it from knocks and the impact of being dropped. Other phone users dislike the lack of design harmony between phones and cases. Many mobile phone users also carry a set of earphones to use with their phone. Most people like to roll up the earphone cable when not in use, but this can damage the internal electric wire and cause disconnection between the earphone terminal and wire. There are many problems relating to earphone cable management, storage, and portability.

Bumper Sound combines the earphone and phone case functions, and by doing so, resolves many of the issues that surround the individual products. The Bumper Sound earphone cable wraps around the edge of the mobile phone to act as its ‘bumper.’ This also creates a storage solution for the cable. The cable takes a flat, grooved format that can provide some sense of design unity with the phone. Being made with rubber, the cable provides good shock absorption.
