A:Answer That headset is Bluetooth 3.0 and Bluetooth 4.0 is backwards compatible, so it should work just fine. There are some profiles that it won't work with, like wireless music control, AVRCP, and Bluetooth hands free profile, HFP. The profiles it does support is wireless stereo listening, A2DP, and Bluetooth headset profile, HSP.
Make sure to check profiles match from the device to the adapter and you should be set to utilize all functionality~
