Summary: When I first got these, they were amazing! After 5 months they would disconnect and turn themselves off, so I got a replacement pair and again was very happy. But now (5 months later) my replacement pair are doing the same thing.
Summary: Worst headset I tried. My ears were in pain after wearing them for 5 minutes. Build quality of the entire headset is good, except the earpiece - I had 1 pound worth headsets that are more comfortable than this one.
Summary: This is the second set of Jaybird headphones I've owned and while they've worked, they've been great. They look good, they remain in place and the freedom to exercise without wires trailing behind me...brilliant.
Summary: I would suggest that no one should buy either these or any other bluetooth heads phones. They do not work, i repeat they do not work. i bought a set of the jaba brand that was top of their range. After twice returning them i was offered a refund. Well done for them.
