Talking from my own experiences, you might try the Sony MDR-10RBT. JL sell them. Considerably cheaper (sadly, also in look and feel) than the M2s, but very comfortable to wear and excellent BT connection. You might want to listen to them - they do not have the same fidelity as the M2s, but they are a good set of headphones.
You might also try the Sennheiser Urbanite XL wireless, which I now have. My first pair had stuttering just like the M2s, but the current pair do not. No ANC (which I did not find effective on the M2s anyway) and you may want to check you like the styling before buying. Great BT and wired performance, and a good sound signature - darker sounding than the M2s (less rich and less airy), but still an engaging and enjoyable listen.
Both of these recommendations are over-ear headphones. If you're looking for on ear wireless phones, sorry, no experience of any. The B&O H8s are even more expensive than the M2s, (by £20), but may do the trick?
