Overall very satisfied with the Jays Five, I am not an expert but I find the powerful and pleasing to the ear. Finally glad I find Earphones with Remote 3 buttons (and configurable thanks to the free application) that runs on Android. Accustomed-ear earphones the only problem I found proviens or too heavy headphones, or too rigid cable suddenly they do not properly fit in the ear and falls easily. The 4 sizes of tip changes nothing.
Of course I just acquire them, if the rigidity of the cable allows the headset to last longer it is not a fault and I will change the rating of 3 to 4 or 5 stars.
