Just had mine fixed May 2013. Came back looking BRAND NEW--I had to double-check to make sure it wasn't a new headset. Working fine 3 months later. Microphone went out; they fixed that plus new cords,new ear pads, acoustic cloth, new mic cover. Cleaned everything after years of MD88 blood, sweat and tears buildup. I'm really happy; total cost $170 plus shipping there (shipping included back to me).

No, I'm not a spokesperson; just pleased with the final result.

Look them up on the web. Sorry, I don't have the web address available. Call and get a return ID number and they'll explain the process.

Hope this helps.
