The sound on these is better than the previous version. The packaging is classy as. Usually headphones will break where you plug them in, but these take that factor away. At first when I bought my very first pair I thought the sound would be fuzzy because they are wireless. Nope, these are crystal clear. I once spent $250 on sony in-ears, they lasted 5 months and that was it. I have bought 3 pairs of these plantronics, way better. Come in handy, subtle. Strong, have not broken (apart from the second pair, that went through the washing machine). People cant tell you are wearing them. No sound leakage in the volume range I use. Volume is much better than the previous version. They hold in place well. Only downside is you have to charge them. I usually get 4 hours out of them.
Bravo plantronics! (the only thing they could do to make them better is battery life).
