I accidently bought the Sennheiser RS160 headphones on ebay without a transmitter. Since I couldn't find the Tx160 compact transmitter on ebay, craigslist, amazon, or from sennheiser, I was wondering if there are other transmitters that the headphones will pair with with no problems.
 
This is my first wireless headphones. Please let me know if the RS160 is worth it because as of right now, i'm considering returning it for a full refund ($99) notwitstanding the 25% restocking fee.
