Ten One Design has created a way to boost the sound for your iPhone 3G. Ten One Design has created a passive sound enhancement product called the SoundClip. The SoundClip increases sound by about 10dB with signal between 6kHz and 20kHz. This would be useful to people that especially love to listen to music through the built-in speaker, but the device just gets in the way of iPhone gamers in landscape mode.
Storing the SounClip is simple. There is a cord-gripping feature that keeps it fastened to your iPhone charge cable during syncing and charging. To buy the device, visit Ten One’s website here.
