I am using this for audio production, listening, gaming and similar.
Its great out of the box, but benefits immensely from a few additions.
Its not as detailed out of the box as it can be, so an equalizer is needed to up the treble by about 3-4db. The low end (60-30hz) also needs to be amplified.
The included cable is short and low quality, and twisting it can make the sound cut out on one ear, so an upgrade to a balanced cable is strongly advised.
Replacement earpads from Dekoni are a blessing if you have bigger ears like me. The included earpads are a bit too small and shallow.
As for the sound, the soundstage is great, its fast and detailed just like planars are supposed to be, and isnt fatiguing to your ears.
Its capable of outputting enough bass for any normal person, but not enough for true bass-heads.
For some reason the bass improves immensely when I lift the headphones slightly out from my ears. Perhaps there's and earpad type that can help maintaine more of that bass.
In conclusion: These headphones are mazing for the price, but needs a few additions, adding to the cost.
