Sennheiser is bullshit. Had 4 different sennheiser headphones (different models, ranging from 50€ to 150€). Every single one broke within the first year of usage. I am now using a Beydynamic DT 990, 600 Ohm. No microphone, but fuck it. Peripheral gaming "gear" is designed to break apart once the warranty runs out.
The DT 990 is working fine since 3 full years now. Was the first thing I bought from my very first salary.
If you love listing to proper music and if the quality of most of your music exceeds 192 kbits aaaaaand if you have a decent soundcard, then gaming gear is not the best way to go. If you can do without the attached microphone, buy something proper, for example AKG or Beyerdynamic.
