"Great sound, mysteriously broken in the posterior arc"2.5 starson by joseruben777
Pros: The sound is really good and "were" light and comfortables, they give the option to select a pre-setted equalizer. The look fine and have a nice thin reflecting trim line in the back. One of the best quality sound that I ever listened for a bt device
Cons: But there's a big "BUT" here! They crack easily in the arc (behind the neck) for some reason. In my case I don't have any idea why they brake so easy because I took really good care of my items. In the beginning they fit really secure but not long
Summary: I heard in different discussion blogs that they change the material for one more flexible. I can't agree that because I don't know, but to be honest they are pricey and for the price I was expecting something more resistant. The audio quality, style, lightness and fit is superb but me as a runner I need good construction, battery life and good sound for motivation. By the way the battery performance is amazing and it charges really fast. I can' not say 1that i recommend them 100% because they are not so flexible as they advertise. Resume; great sound, wonderful battery life, comfortables, lightweight, humidity or sweat resistant but...... In my case they brake whit-out to much effort....
