I?m only slightly ashamed to admit that I use a Bluetooth headset around the house/office, a tiny model from BlueAnt. But while its compact size makes it easy to wear, it also limits the number of buttons on it, making changing settings or adjusting the noise cancellation a ridiculous series of timed button presses that I never bothered to learn. So I have to say I?m quite surprised that the Sound ID 510 Bluetooth headset is actually the first to come with its own iPhone app, EarPrint, that makes changing settings, adjusting the volume or EQ of the sound and monitoring the battery life ridiculously easy.
The app is of course free on the App Store, but only works with the Sound ID 510 BT headset, which itself is no slouch. Its noise cancellation uses 3 separate mics to eliminate wind and other noises, it can be connected to 2 phones at the same time, has 5 hours of talk time with 135 hours of standby and the outer surface is a touch sensitive strip allowing you to adjust the volume (when your iPhone is inaccessible) by just sliding your finger across it.
