I have brought a pair of Sennheiser headphones, and the quality is very good, in fact the clarity is so good that when I use it with my PDA I can here a very slight white noise type sound, but I don’t get this with other equipment.
Noise cancelling is created by the seal that he silicon covers create. I used them on an aeroplane and although the background noise was still slightly audible with the earphones, when I did take them out I realised how effective they were. to simulate this if you put your fingers in each of your ears the sound produced sound a bit quieter than the background noise that you hear on an aeroplane.
They do take a little while to get used to but over a few hours they still are comfortable you don’t get that hard pressing of plastic in your ear that can start to hurt or ache with standard in ear headphones.
If you are looking for professional quality in ear headphones these have to be one of the very best.
