These headphones do not actively cancel out background noise, but do a fair job at blocking out the background noises.

I use them at my work desk to drown out the background noise and the weird guy next to me.

i don't notice any discomfort and they are great at cancelling out any background noise)which takes getting used to

Tried the 201s first and they were terrible, weak sound and s***ty feel, returned in 20minutes. as well as the 202. figured at $50 these would be decent

They have a very rich, and FULL, sound I always like, especially for music.

The product worked perfectly I needed a inexpensive VH-C to VCR adapter to complete the conversion of tapes to DVD

and i hard more then before , nice clear

I bought these headphones in a pinch to replace a pair of Skullcandy Titans that had broken--I didn't want to bother with a warranty claim, as they never sounded very good anyway
