I tried the Nokia headset along with a Nokia N73. I love the lack of wires, portability, and comfort, but the sound quality can't compare with a good wired headset. You'd buy these for the toy factor and the convenience.

The bass is very strong, way too strong, it drowns everything else out. The mids are muffled, and the highs are rolled off. If they weren't wireless they might be worth $30.

The volume control is also hard to use - it's hard to set it to a reasonably quiet setting. They go incredibly loud, they should really have limited it to prevent hearing damage. I would call that irresponsible on the part of Nokia.

Overall: thumbs down. I wouldn't spend that kind of money on headphones that sound like this. If you love toys, portability, and excessive bass then you might consider them, but do yourself a favor and try out a few different types of headphones before you settle on these.
