It is still new, but the sound quality is excellent, compared to the previous ones I had, it's a completely different category, there is nothing in which it is not better. My only concern is that the cable is not detachable, but in forums they say that the cable is fine and does not break (although it looks fragile), I don't have an opinion yet, if they break, I will come to inform.

They haven't suffered anything at all, but I wanted to say a few more things.
In terms of bass, unlike many headphones that emphasize sub bass, these ones are calmer and emphasize high bass. The mids are generally warm and the upper mids are slightly recessed, which makes them very relaxing to listen to, the trebles are present, but never take the spotlight. In general, nothing takes the lead, it is a very calm, integrated, and mature set.
Now about the cable. It hasn't suffered anything, and I have to say that it is a very easy cable, although it tends to pick up noise, unless you wear it over the ear, then they don't pick up noise. It comes with some rubbery things in the box for this purpose, personally they didn't work for me and I have thrown them away now. I wear them normally over the ear.
