Plantronics Discovery 640 Cost £49 For Great design; accessories Against Picks up some background noise Verdict Great for gadget-lovers and it works well
The Discovery is a very stylish unit - it looks like something James Bond might use. It also has enough accessories to keep Bond happy. You get a variety of power adapters to the most popular mobile phone chargers, an add-on that lets you charge it from an AAA battery and a natty case to keep everything in.
The unit is comfortable to wear and surprisingly stable using the in-ear bud, but you can fit the supplied ear band if you prefer.
Overall sound quality is good, with a high-level volume control helping you hear in noisy environments. The microphone picks up a little too much ambient noise, although there is no distortion at any time.
