I mainly listen to (symphonic, power) metal music. After long listening, it is strange that they sound very similar to these ATs in terms of sound. The main difference is that they have more noticeable low bass, nicer female vocals and play the high registers of instruments better. Additionally, they are less flat in terms of space and the separation of individual instruments is better. But for some reason the K702s have more bass than the ATs which are known for their basses. The K702s were supposed to have almost imperceptible bass (even barren sound due to the lack of bass), so I wonder if something strange is happening with them. Even YouTube ads sound like a movie trailer using the K702.
Try listening to this song https://youtu.be/hqRFWCbQ9Lk?si=PmapcsbC3KQQI5su for example using the K702. Based on this, how present is the bass in your unit? The problem is that the bass seems to be closest to the ear (probably just louder) in relation to the mid and high tones. So when you turn up the volume of the headphones to hear the mids and highs, the bass is unfortunately very disturbing because it is loud.
