I've gone through a few different Bluetooth headphones, and these are some of the better ones I've used.
No, they're not gonna give you the audio quality of an IEM like something from jaybird or Sennheiser, but those suckers are well over 150$, so for under 30 bucks, you're not beating these, as they're basically your standard skullcandys with a Bluetooth connection.
I have only one complaint... The freaking battery module on the back. Of the several Bluetooth headphones I've used, these suckers are freaking hard to keep in your ears, as that Bluetooth/battery module in the middle flops everywhere. Now that would'nt be such a big deal if there were some shirt clips to hold it in place, but for some trivial reason Skullcandy did not include any method of keeping that wire in place, so unless you get some clips, that thing is gonna be flopping around all over the place, and sometimes even pulling a headphone out of your ear. Luckily for me, I'm almost always wearing a hat, so I just throw it up in my hat, and it doesn't give me any problems. If I didn't, clips would be a must.
Connectivity is decent, occasionally the volume will dip for a split second when the connection suffers, but it's not often, and for how cheap these things are, it's amazing they have as solid of a connection as they do.
Bottom line: worth the price, but get some shirt clips if you're planning to use them for any sort of activity.
