Lastly I bought AKG K702 and also i have Audio Technica M50X BT. I’ve read a lot of reviews about akg saying they are headphones with little bass (what I want), pristine sound full of space. Based on these reviews, I’m afraid there’s something wrong with my akg, as they have more bass than the previously mentioned AT (especially more low bass), they have a lot of space of course, the mids and highs are less than at, they are a little muddy. Every hit on the drums has a big impact (more than an AT). The impression is similar to that of a movie trailer, where the sound is spatially bassy. This is a recent purchase, so it is possible that they still need to warm up (in AT warming up had a big effect), but I am afraid I got a defective unit. It is possible that this impression is somehow caused by the space, but I fear that something is wrong with the driver or the cable connection. Maybe someone knows something about this phenomenon, has some experience. Thank you in advance for any suggestions.
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.
