Mobile Needs, via Amazon, is selling what it describes as a “100% Genuine Black Stereo Handsfree Headset” for £2.85. Comes with a little button to play, pause and skip tracks, and answer calls, and all cheaper than a Big Mac Meal. Oh, and it has a 4.4/5 rating after 32 customer reviews. Not too shabby.
The item listing states the HTC Wildfire S specifically, but we're hearing that the "stereo handsfree headset" is compatible with other Android phones.
Mobile Needs has a 4.9/5 rating over the past 12 months.
