I just bought a pair of sony mdr-v800 headphones. They sound great, at least to my untrained ear, but when I listen to music (not games), my ears start to ache. I'm wondering if that means the headphones aren't as good as I thought, or maybe it is because I'm not used to harmonics below and above the range of hearing? As for the other question... I've been surfing this forum about bose speakers, having recently heard their not all their cracked up to be. I read the intellexual breakdown, where it talked about all the shoddy materials and such. I've also heard that bose tweaks their amplifiers/mixers to disguise the flaws, and to a good ear it's pretty agonizing. Is that true?
