First, my main issue with the SYNC headphones was that while they are wireless, many of the controls for music play did not work wirelessly

Obviously not a major issue, just a little annoying.

This is by far the most frustrating issue, because if you can't listen to your music/podcast/conversation without it being choppy, what's the point?2

but these two major issues really suck.

They sound great, and the only issues I've had were with the third party bluetooth

However, if I connect and re-connect, it typically clears the issues up.

The biggest issue I had was the bluetooth static / feedback noise.

I don't have this problem with any other Bluetooth devices I own (a wireless speaker, my iPhone, or my camera, so it's definitely not an issue with my computer or Windows 7 generally).

Only issue is if you use it during exercise (I do) and sweat on the top head piece, it's not really easy to clean since it's cloth material and not really removable

I tried a bunch of the other Jabra headphones that are in-ear, but I ended up returning them because of bad comfort and connectivity issues

Connecting causes buffering and stuttering issues

But I will say that these issues are relatively infrequent and shouldn't really dissuade anyone from purchasing them.

The build quality is good for the most part but this issue with the bass is definitely not great.

Overall, I'll give it 5 stars and overlook the mic issues, as I would have paid this price for these headphones even if it didn't have a mic at all.

Importantly, I have had no issues with the ear pieces falling apart

But I would recommend spending a bit more on something of slightly better quality - especially if you want to avoid tedious issues like these.

There seems to be a significant bluetooth electrical contact issue, as the left speaker stopped working in bluetooth mode immediately.

It isn't bad enough to make me not use them or send them back, but I am going to have to work on them to see if I can improve this issue.

I like physical buttons, easy to use and kids friendly.

Another positive I have not mentioned is the surprising longevity of the headphones

For 60 bucks these are a rock solid pair of Bluetooth head phones they are not as loud as the JBL’s but they do block out office noise
