Pros: Okay first off: NO CABLES! Damn this is ideal! I wish there where many more (brushed metal?) like this one.
Sounds quality is nice too! Also Vista detected it and was able to upload music, quite fast, within like 5 sec (first time it investigates the hardware, second time it was instantly ready for use)
It's great if you sport often or use a bycicle. Very comfortable and you can wear it in a way only one earphone is in use (to stay aware of traffic sounds) GREAT product!

Cons: Built quality: had once a button went inside the device, could get it out on the instant but still... buttons are small.
Also there are 3 buttons for 8 functionalities:
On off play stop is one (depending on the preassure time)
Volume up, next song.
Volume down, prev song.
There is enough space for more buttons so: why not?

Other Thoughts: More designs and an expensive variant with 2-4 gig and brushed metal! :D

Bottomline: Great product, you have to get used to it but if you do you're going to like it. Also it was here VERY quickly! Nice one DX!
