The old saying is true: you get what you pay for. I bought a pair and just received them. Here's the pros and cons.
Pros: they are Bluetooth headphones and are fairly easy to sync with your device. The ear buds are decently comfortable. Also, you get two pairs with each order! Yay.
Cons: audio quality is tolerable but not fantastic (again, you get what you pay for). Additionally, the weight of the control rectangle makes it so they are always sliding off your shoulders. As such, these headphones can not be used for exercise.
Summary: If you and a friend don't care about sound quality and are going to remain motionless while using these then have at it.
Note: I purposefully left off the quality of using these for phone calls as I haven't tested that at all. I also can't speak to charge times but I have run them for a solid two hours without them dying.
