These headphones are amazing! I had been looking for lightweight, wireless headphones for years - I even bought a couple that were either very heavy or just didn't work.As other reviewers have mentioned, these headphones work best when you turn off your tv's speakers and adjust the volume on the tv and headphones; I encounter major static when I don't do this (this is the only reason I didn't give them 5 stars). Otherwise, they are perfect and, on my recommendation, my brother - who demands perfection - also bought them and also loves them.Good job, Sennheiser!Update:I have been using these headphones for more than two years now and they still work as good as new (and I use them almost every day). Love them!!!
