people are saying the highs of even pk1 shy in front of aurvana air, which I got for 40 bucks last thanksgiving or this past spring i forgot. and i think the best earbuds under 50 in any circumstances should be the k318, and before k318 came out the legendary k314p. of course bassheads(people that can't stand music genre and headphone genre without bass enhancement) can turn around and keep walking---at least people have been trying to make products that are actually good AND cheap, better than beats and you are a friend
