Pros: Great sound quality at low price
Cons: bass is somewhat boosted
This is my first review so i hope u like it.
Soundstage: it is very good, clean instrument separation with some space to spare, just nice to turn on Dolby Headphone mode. I have heard a better soundstage in an open-ear design but this one doesn't include other sources of noises like kitchen or a phone or a dog barking etc.
The sound quality: at beginning i was wondering why the bass is so punchy and overpowered-like, this is fixable by tweaking the EQ so i set 60hz -8dB, 120hz -9dB and 250hz -6dB - oh man how they output 30hz now, just pure heavy bass clean vibrating powahhh (Azedia - Thunder & Lightning, makes extraordinary bass so its not like empty BOom, more like deep vibrating WwWwWw) but for my imagination they do uncover themselves on my ears - not on the stage of the sound because of that bass. Middle range is a bit recessed but i like it like that, because of singers voices most of the time they sing directly in to your ear and not like on actual concert hall. About high frequency - yes there is a lot of that i didn't test myself but i think i couldn't get any higher pitch with more expensive pairs so there is precision and quality and you do hear difference between youtube and FLAC. Xonar DX sound card can drive them just fine but it cannot destroy them - i wasn't able to hit the hard wall even after tweaking 30hz to the max at maximum volume.
Build quality: plastics just look awfully cheap but with a bit of good 3d engineering - hope they wont break after a while (fingers crossed). Wearing comfort is fine not super ultra fine but good enough to not drive me any pain.
So my conclusion is - if u can get them at 73$ or less brand new just do, it is a steal, but be careful and save in mind these might be fragile.
