They do not cancel background noise all that well but that ways not a feature I wanted, I need to hear what is going on around me

They don’t cancel much background noise, but I was

They block out any background noise.

I found that they work fine if you're indoors and there isn't any background noises around.

I do editing with sound and found the Sony headphones had excellent voice reproduction, and really pretty good on music, audible background noise than the Bose.

The ear cushions are designed so I can still hear background noised, phone, secretary, front door, ect.

Tunes out background noise and sounds like you're sitting in a theater.

Doesn't quite cancel out background noise

Also, just to let you know, the earpads are made of a material that will probably deteriorate as they get older

These broke as we pulled then out of the box

Fit just right, not too tight on the ears, but not too lose as to fall off

For Money :=============As far the 9USD price point is considered the product is a worth the money

They would also work well when you are trying to not bother others such as in the office, bedtime, you name it

He finds them comfortable and the sound quality is as good as to be expected

I bought e Geuray portable CD player through Amazon and needed headphones
