HmmmIf I were buying again today I would still go with the wired ones because: the price difference is substantial ($50 at Amazon); a number of reports of connectivity issues in Amazon reviews; and the wire does not bother me. If the price were the same, I'd give the truly wireless version a try and return them if I ran into connectivity issues.
I read the frees have better sound quality
I don't mind paying the extra if its worth it
I also have the read the build quality isn't great on the sound-sport wireless
