Ok so let's start with build quality. Well first let me get the elephant in the room out of the way and address the hilariously large headband. With that aside the overall construction is very solid for being a $40 set of cans. Plastic doesn't feel flimsy like it's going to break anytime soon as opposed to my Superlux EVO's (which the headstrap already has). Pads aren't removable but they are velour and clamping pressure is comfortable.
Sound: Everything I'm mentioning basically parrots the head-fi reviews as I am in full agreement. These cans are not for bassheads. Bass is tight but lacking, mids are there without being overly nasally. Guitars from metal and violin strings from classical/symphonic music sound really nice. Haven't noticed any sibilance in the highs yet but I'll edit this post if I find any albums that bring out any shrills. So far I've tested Megadeth's Peace Sells But Who's Buying, The Skyrim soundtrack, some Vivaldi ,Paganini, and Massive Attack's Mezzanine. If you're into rap or any type of electronic music then look elsewhere. Mezzanine sounded better overall on the Superlux EVOs due to better bass response but I think I prefer the mid range trade off. I guess it's a toss up between these two headphones. EVOS: better bass but recessed mids or the Takstars.
I know this review isn't that great but it's a starting point if you're interested in some low cost headphones for similar types of music that I mentioned. I wish you all well on your unquenchable sound quest. :)
