Logitechshop Ultimate Ears TripleFi 10 Earphones $199 including postage
I trialled a pair in the office and they work well to block out all of the background noise - even at a low volume. Read the reviews. They wont fit all ears but you can buy a large range of different clip on foam/silicone buds. Replacement cables can be readily purchased, these clip into the earphones. You can also now buy cables with built in microphones so you can use with Blackberry and iPhone mobile phones.
