I bought another pair of headphones a week ago, and had to return them because, although they were by a very reputable brand name, they were totally the wrong shape for my head and kept slipping off. In addition, there was a very audible background hissing which proved rather annoying, especially as I listen to a fair amount of minimal techno.
I was therefore rather dubious about investing in another pair, but I must say I am extremely pleased with the Philips SHC8545 headphones. First of all, they fit very snugly and have a very aesthetically pleasing design. In addition, the sound quality is good, with no audible hissing whatsoever. Quite a surprise from cordless headphones, as the radio transmission usually implies a certain amount of static.
The reception on these headphones is great, even when walking all over the flat. I really like the automatic tuning device, and appreciate the fact that it is a button rather than a wheel, as on the other headphones I was apt to confuse the tuning wheel with the volume one.
The previous heaphones would deafen me with static if I didn't unplug the audio jack before turning them on every time, whereas these were perfectly simple to install: I simply plugged in all the cables, inserted and charged the batteries, and hey presto.
I would thoroughly recommend these headphones, especially to people like me who don't have the huge head required to wear most good quality headphones!
