K-371 : Probably best sub 200€ choice

As the title says: In terms of sound this is a very solid option. Frequency response is flat except for two parts, which you can easily account for when you know them: Its a few dB sharp in the 2.5kHz range, and sub 200Hz its boosted by around 5dB. The latter is actually pretty nice to have as you can easily hear whats going on down there. And even though the headphone has some trouble reproducing finer details, its sound is remarkably clean. Just take a look at the charts on diyaudioheaven and you'll see what I mean.

However, as long as you haven't worn them in, the comfort is absolutely terrible. I couldn't wear them for more than 5 minutes in the first week. After a few months of daily use, they are fine now, but I still sometimes get a headache from their clamping force.

Build is amazing. Its all plastic and the pads are synthetic leather but it feels so quality. I could touch it all day.
