Sound Clip is such a thoughtful design solution to limitations that make iPhone’s speakers almost suck, it’s a wonder they didn’t think of it first in Cupertino.
A conical deflection chamber that reflects volume towards the user instead of away, the device is said to amplify sound by 10dB between the 5kHz and 20kHz frequencies. The SoundClip fits in the iPhone’s 30-pin dock, and also helps prevent users from blocking the iPhone speaker with their hand when playing a game.
For $8 and a barely perceptible modification to the iPhone’s svelte form, you can improve its sound appreciably.
