Review title: What a gimick! Totally useless
Product review: I bought these, based on the specs (claim to go down to 15Hz). The vibrating thing might fool you into thinking there's some thumping bass behind your head, but the overall response of the speakers is nowhere near that good. It's like the mid-range is barely audible, and aside from the bass you would normally feel instead of hear, you don't really hear any bass at all. After wearing these things for half an hour, I had a headache. I wouldn't buy a pair like this without a good test-run first.
