Fairly easy to install, but I?m pretty mechanically inclined, so I don?t think it would be as easy for others. Mouse is very very bad. We had 48 GB of music. I find them to be as comfortable as the Beats, so much so I forgot the first time or two that it wasn?t my Beats, but even the active noise cancelling is as impressive. I had music on in the background on a different device quiet enough that the mic did not pick it up at all, but I could still hear it through the headphones. Well, that was a mistake. I dont regret parting with over £110 on these as the quality is fantastic. The material on the bench was torn. I like this product and since I?ve been grooming my kitten daily since she came home she doesn?t mind this. Therefore overall, I would NOT RECOMMEND THESE.
