If you use the supplied cable that came with the Bose QC25's it should work perfectly... although the cable is rather long.

What you are looking for is the TDK Bluetooth Stereo Clip In-Ear Headset BT-100 with Built-in Microphone. Its tiny and should do the trick... you just need a male-male cable... and double check the pin-outs on the connector i have a feeling Bose wire their connectors differently.
