Summary: Firstly, these cans do indeed pack some bass and the design is pretty cool, but that's about the only positives I can find with them. I suppose they aren't very expensive there is that, but in this case you get what you pay for.
Summary: These products lasted 2 months to be exact. Has great sound / bass quality then all of a sudden you start to hear weird vibrations on both sides and to stop the vibrations you will need to push both sides closer to your ears.
Summary: The right speaker just broke after three months of barely using them. The sound is not properly isolated inside the headphones and you cannot turn the volume up if you are in an office without everyone hearing your music. I find this headphones quite uncomfortable to wear. They are quite tight.
Summary: Bought these about half a year ago and have survived. The sound feels like you are listening to you're music through a wall. There is a lot of noise leakage but they are very very sturdy. I have recently purchased a pair of replica beats for £20 which have turned out to be far superior.
