I've had numerous sets of headphones over the past few years, but had never owned a set of wireless ones. I bought these headphones a few months ago for £25 and thought I'd give my review. Seen as I don't use headphones all the time, I didn't want to spend a fortune on my first set of wireless ones. 
Even though these are on the cheaper end of the market, they are still packed full of features. Easy pairing with your device means that you wil be listening to music in no time. The bluetooth range is around 10m which gives you the freedom to roam around while still listening to your music. They claim to have up to a 6 hour battery life which seems to be pretty accurate from using them. 
The sound that these pump out is impressive with a decent bass and clarity. They are more than loud enough whenever I have used them, and they are comfortable to wear compared to ones I've had in the past. They are on-ear headphones so the sit on rather than around your ears, but still block out a lot of external noise.
Another neat little feature which comes in useful is that you can use these as wired headphones with the supplied 3.5mm aux cable, so if you have a device without bluetooth connectivity you won't have to reach for another set of headphones. 
They also have a set of controls on the right hand headphone so you can either play/pause the music, or alter the track and volume. This come in handy when i'm playing music from my laptop while doing something else, as it means you don't have to go back over the laptop every time you want to one of the settings. 
Overall, these are a great set of headphones by Kitsound, packed with neat little features for a very reasonable price. If you want a set of wireless headphones without breaking the bank, you can't go far wrong with these!
