These bluetooth headphones do a lot of things right, but unfortunately, I found them uncomfortable to wear most of the time. Right out of the box they're not hard to set up, despite the instructions being less than clear in English. If you've ever used Bluetooth headphones, these will set up in the exact same way. The problems started when I first tried to put them on, as no matter what I did I could not find a comfortable position to sit these. The angle shown in pictures looks simple enough, but every time I picked these up to put them on I had to wrestle with them for several minutes just to get them to sit in my ears without causing me discomfort. Even when that was done, I found the cable that attaches the two headphones to be just stiff enough to be annoying, as it was not easy to adjust and I was keenly aware of it at all times.

Once I was finally able to wear them, I found the audio quality and noise cancelling to be pretty much average, nothing wrong but also nothing particularly impressive. I did like the way that the controls are set up, with the buttons being on the headphones themselves and allowing you to pause/play, adjust volume, and skip/rewind songs. You can also use these headphones to make and receive phone calls, and the microphone that is inside the headphones did a good job of being about as clear as I would expect from small Bluetooth headphones.

You can also sync these headphones to two devices at once, which is useful and a really nice feature if you keep a work and personal phone, or if you want to keep an ear out for calls while also listening to something on your tablet.

The other major issue I had with these headphones is the instructions that play when you do things like sync them to a device or turn them on. All of these voice instructions are in Chinese, and it is impossible to change them to English. Not even having a language option is a major oversight, and is a constant reminder when using these headphones that they are not well designed.
