I was very excited when i purchased this headphones. At first i used to carry them everywhere i went, and used them on all my devices to optimize my listening experience. after about 4 months i stopped carrying them everywhere and only used them when i needed them. just before i stopped carrying them around, i noticed that they would have static noises whenever i plugged them into any of my devices. after 6 months, i noticed that one of the ear pieces was no longer working properly. it would not work whenever i plugged them in to any device and normally had to re plug them in and press on the top to keep both ear pieces working properly. 
in short, they are very expensive headphones and one would expect them to work for a very long time considering their cost. but for them to have issues in less than 1 year, i would not recommend buying any other beats headphones especially the earpieces. they are just not worth it!
