Sennheiser GSP 370
Broken
Owned for 3 years, used Daily
Stress Points- On / Off switch broken - Fortunately the battery lasts a really long time, and I try to keep it charged when not being used, but the switch (which I think is a terrible design to begin with) does not "catch" in order to activate the off position. Due to this I cannot update the firmware.
Sometimes the mute / unmute does not work on the mic arm.
At one point the headset froze, with a repeated buzzing noise, and I could not turn off / reset the headset, so I turned down the volume and left them running until the battery died and they worked better after that.
There is another review on this but the earpads started splitting and coming apart after about a year, there were replacements online for about 20 dollars that were better quality, and have lasted me 2 years with no issue, but you shouldn't have to pay extra to keep your headset comfortable. 
Positive Remarks- The sound quality is great, they are nice, professional looking headsets.
- Would you buy it again?
No
