MMX, Repeat Customer

This is my third pair of headphones by Beyerdynamic. Ever since I purchased the DT770 in the early 2000’s, I have dramatically reduced the need for anything headphone related. The old DT770’s lasted so long and built so well. I even had them serviced, and they did a great job and gave me a couple sets of earcups for free. I purchased the gen 2 mmx phones that still run and sound great. I built a new pc, which I do every 8-10 years, and even though I did not need to headphones, I treated myself to the new 3rd gen. These are my new gaming headphones, and the gen 2 mmx phones are dedicated to my drums now. Beyerdynamics hits hard, gets loud, feels great and look even better. The sound quality is amazing. 2 headphones in 20 years and I still didn’t NEED to upgrade. It will be a while until something can replace this company. I’m a big fan.

These are fantastic, the audio quality is on a level you don't really understand until you have to use your normal headphones again after using these. I will say that the clamp force is a little much and its mildly uncomfortable to wear, but I will get used to it, and the sound is unlike anything I've heard from desktop headphones. the microphone is also top notch, I've never sounded clearer
