Ten One Design has introduced the SoundClip, a new passive sound enhancer for the iPhone 3G. Made from a single piece of plastic, the SoundClip attaches to the Dock Connector, and is designed to direct sound from the iPhone’s built-in speaker towards the user. In addition to serving as a port protector, the device also prevents a user’s hand from inadvertently covering the speaker during activities such as gaming, and attaches to the iPhone’s sync cable when not in use. According to the company, SoundClip amplifies iPhone audio by 10dB between 5kH and 20kHz, and improves frequency response, as well. Ten One Design’s SoundClip for iPhone 3G is available now and sells for $8.
