If it weren't for absolutely uncomfortable design (too big nozzles, too big body), this would be a decent IEM soundwise - not stellar, but OK. I literally can't fit these in my ear, no matter what tips and even when I managed to fit them, after a short while, it became really uncomfortable. I don't recommend these if you can't try them before buying.

Personally, I see as the main issue how boring, unengaging it sounds. I dont really feel like I am in direct contact with the music I am listening. Besides, there is slight muddiness. Still recommendable, but from all the hype for these headphones being recommended everywhere across the internet, I would expect better. I am not keeping these. In direct comparison with Beyerdynamic DT250, I can immediately tell how much more lively DT250 sounds. Yes, they are closed and have some issues too, but anyway, in comparison of these two, I really had no...

Test gear: PC -> USB to Focusrite audio interface/DAC -> line cable -> Fiio K5 Pro - Beyerdynamic DT250 250ohm/Etymotic ER2SE also tried: PC -> USB -> Fiio K5 Pro - Beyerdynamic DT250 250ohm/Etymotic ER2SE The thing is, I compared Fiio back to back with the headphone input on my 20 year old Kenwood home stereo (no high end at all, just a common small, consumer home hifi, albeit a decent sounding one) and the sound was either comparable or even better in overall character on the old Kenwood (!). Yes, Kenwood distorted on high volume, while there...

A very nice sounding IEM. Totally recommendable (unless you are a bass-head, need a strong V-shape, or can't tolerate a deep fit construction). The good reputation/hype well deserved. Balanced, clean, euphonic sound.

Positive: Very nice sound overall. Clear, accurate, revealing. Very nice sound especially for being closed headphones - in other words, the nasty closed-headphones congested and plasticky character is not there too much. Nothing distracting in their sound. Balanced. They can handle quite high volumes without distortion. The sound is quite punchy and lively. For under 100€ these are a VERY good value. Probably very nice value in 150€ range still (but maybe there is something better, I dont know though). Neutral/possibly negative: Not much sub-bass...
