beyerdynamic MMX-300 2. Generation

The headphones developed an issue with the volume knob whereby if you roll the volume wheel up or down the sound cuts off from one side. This 3 years warranty that Thomann keeps harping about means that even if you clearly explain and relay your issue to them, they'll want the product for 3-4 weeks and then you might get it fixed. In my case, it's a clear cable issue and I'm not prepared to be without sound on my computer for 4 weeks simply because Thomann wants me to ship it half way across the world instead of honoring the warranty and replacing the obvious faulty cable. I thoroughly regret buying from Thomann, it left me with a really bitter taste in my mouth and also with a product that takes fiddling to get it to work before it stops working again. Avoid if you can or be sure that you're prepared to be without your product for weeks on end if something goes wrong.

I was so excited to get these. I remember loving the 770s when I had them on loan for a week and yet these sound.. hollow. Maybe the soundstage is too big but it sounds like the music's playing from at least a kilometer away. I seriously don't know what's wrong with these, I tried plugging them into everything I have: my old iPod Classic, my 2015 MacBook Pro, my desktop PC, my Mackie Onyx 2.2 and I even borrowed my friend's fiio k3. It made no difference whatsoever. I can hear nothing but treble. The bass is practically nonexistent unless you listen to somethng where you only have a bass playing, like the intro to Another One Bites The Dust. Entire instruments disappear (electric guitars, violins, etc) and all you're left with is what sounds like artificial reverb.
