Summary: I bought those headphones about 4 months ago and used them with great pleasure for about 3 months, when all of a sudden the battery lasted for only for 25 minutes (with full charge) then 15 minutes....then 5 minutes....now they will not even turn on. Totally disappointed by this investment. Not fair...sorry! But while I used them they were awesome - delivering the best music experience cordless..
Summary: The first set died in four weeks and the second set in three months. I have the third pairs now and waiting for when will happen again. I think they are not completely sweat proof. Because they both died during running. Replacement is a big issue, if you live a country where there is no jaybird support and apple store. I replaced my third pair in Hong Kong apple store where i bought it. They first refused to replace it, then changed their mind.
Summary: I was given a pair of these earbuds as a gift in February. Once properly fitted and paired they work great. Unfortunately, I've had 3 pairs quit on me. I wear them running and they get very wet from sweat, I'm assuming this is the problem. All 3 pairs quit mid workout and would not power back on (after a full charge). I really like them, when they work, but unfortunately I've had it with them. Time to move on.
Summary: I recently bought a pair having used the original Jaybees for some years. The sound quality is fantastic and the comfort and fit exceptional, however.......they worked fine the first time out, but the subsequent 3 times after a full charge, they have shown full charge on the new battery icon on the phone yet after 20-30 mins they repeatedly try to dial my last called number and then shut down without warning and then won't reconnect until after another full charge then...
Summary: Great sound, awesome fit, and love the wireless, but alas, they did not hold up. After about 3 weeks, and right in the middle of a run, they cut off and I was never able to get them to come back on. I exchanged them for another pair at Bestbuy and within the next week they stopped working. In the middle of crossfit session and they continued to redial my phone repeatedly before shutting down completely. Again, could not get them to come back on.
Summary: I just sent back my third pair of jay birds bluebuds x units. They all started out working and sounding terrific at first ...but after an hour or so of running/working out they just power off on there own for no apparent reason and will not come back on. Extremely frustrating. The jay birds service person I spoke with says perhaps I just sweat too much. :-/.
