Are you sure it's the TR130? Because I'm seeing people reference the actual model to be RS130. (Well, went from SR130 with little results, then found several results for the RS130.) I also saw mention in one manual of a TR130, but it was in reference to the transmitter on another model.
The RS130 is a Bluetooth Headset from Sennheiser: http://safemanuals.com/user-guide-instructions-owner-manual/SENNHEISER/RS%20130-_E
If this isn't what you're looking for then apologies. Best of luck.
