I had the previous version of this product and as far as I was concerned it was unusable because of all the connection drops that I experienced which completely ruined my listening experience. So far with this version (v2) I have not experienced any drops at all under all the same conditions that I had tried to use v1 in. I am using this with Shure 535 phones, sound quality is not as good as with the cable but I am very happy with the quality that I get and the volume is good too, something that I have not found in any other bluetooth product that I have tried. If there is a negative it is that the buttons on the remote are not easy feel and distinguish from each other but it works. Overall I am very happy with this product!
