Title: Pretty good, so far.
Review: I like these much better than the Sony noise-canceling headphones I bought about 2 years ago. The Sony model created an uncomfortable feeling of pressure on my eardrums. Noise was reduced, but the noise-canceling was uncomfortable for long periods and made me worry that it was going to damage my hearing.These Philips headphones do not create that sensation, and the noise-canceling works well enough. Unfortunately, I started getting a very high-pitched sound in the right-headphone today that varies in tone, especially if I tap on that side. It sort of sounds like the whine you get when tuning an AM radio. It seems to come and go, but it might just go beyond my range of hearing. If it continues, I'll try trading them in for a new pair to see if it's just a defective unit. So far it seems to only happen when connected to my iPod with the noise canceling turned on.
