Yes, as in my sig, I have the MK2 and and the HK BTs.. I took the Sony 10RBT back, because I had the higher Sony. The 10RBT were very good at their PRICE POINT. I paid $150 for the 10RBT, that is why I said they were good, with their price taken into consideration. On the comparison, I don't have golden ears, in fact a long ways from it. All I can say, the MK2s were better than the other 2 in every area except price.
