Hello, consolemasterac,
Strictly out of curiosity where did you find the Sennheiser GSP 650 headset? Sennheiser doesn't seem to offer any higher than a GSP 600 for $249.95 plus tax. I use Sennheiser equipment, mics, headsets, etc. in my production studio, I admire you for being able to spend $250.00 for your gaming headset and if you are in your first 30 days of ownership Sennheiser will take them back. Here is some info on returns; The Sennheiser store by Digital River offers a 30-day money-back guarantee. To request a refund, you must call Digital River Customer Service at 1-(800)-598-7450. Here is the return info if your item is out of the packaging please mail it to this address:
Sennheiser Electronic Corporation, 1 Enterprise Dr, Old Lyme, CT 06371
Good luck with your headset issue.
Respectfully,
Carl Hataway
