Be Excellent To Each Other

Has anyone recently replaced wireless headphones from turtle beach, leaving them with a spare transmitter? One of ours is broken and every other part continues to work with another transmitter. I could get a refurbished headset with transmitter for about £40 on eBay but if someone had a spare I'd much rather just give them £15-20 and only have to pay for the transmitter on its own.
I think it's a bit of a long shot but I thought I'd chance it, I doubt anyone has had to replace a wireless headset to have a spare transmitter lying around!
