I purchased these headphones as an alternative to some cheap ones I had been using and had no troubles with. Upon receiving the item they came in an undamaged box with everything that should have been included with the headphones.
As the week went by with constant use at sensible levels of sound, I started to hear a buzzing noise in the left ear pod, I was puzzled and decided to see if the buzzing would go soon, it did not. The buzzing continued and started to get worse. This has happened remember after only a few days to a week of use.
Therefore, I decided to not bother with a replacement and got a straight refund and spent the money on saving for a new laptop.
Still an okay pair of headphones if you don't buy any lemons.
