Got them 2 days ago from amazon.co.uk. It has uk plug, not like the other guy's review said.
Good/very good quality of sound- bass, treble, it's all there. No problems with reception through my thin toilet wall.They loose reception when I tilt my head sometimes and it happened in the same room. When level of sound is low in any of channels it turns off speaker for split second(probably to save battery).There is no hissing, sound is clean.
Comfort on my head not too great.Ear pads are too small and after 30 minutes you start to notice there's something on your head pressing on ears. I've got XL head but these headphones fit and stretch no problem.
One more thing.I asked Philips if these could handle two sets working from one signal source and I couldn't get clear anwer but possibly they can if set was bought in UK(I think:-)).I'm considering another pair for my lady so we could watch movies late night without disturbing neighbours. I could always get a splitter jack socket.
Hope it halp you people. Thanx
