The Philips SHM6100 headset is an amazingly light model. It fits behind the head instead of on top of your head, eliminating that dreaded headphone-hair look. It's also got an adjustable microphone that rotates almost 270 degrees, though why you'd want your headphone directed to your ear, I don't know.
Because it's so light, you'll barely notice it even if you have the headset on for hours at a time. I have a small head, however, and sometimes it will keep slipping down on my ears and that makes it slightly uncomfortable.
Sound quality is great; apparently the bass has been boosted in this model and it definitely feels like you're right in the middle of the action if you're watching a movie, or next to the person you're speaking to if you're making a web call. The microphone is extremely sensitive (that's a word of warning) so you might want to change your microphone settings, or point it slightly away from your mouth (oh, so that's why they needed 270 degrees of motility).
Value for money
Well, I got this overseas at a ridiculously cheap price, about half of what amazon.co.uk is selling it for. But even at £8.95 I'd say it is a pretty good deal. It's light enough to take with you everywhere and small enough to not be obtrusive. Also, they're much more comfortable than earbuds and are infinitely more hygienic.
