Summary: I chose this product after reading a lot of reviews, both user and 'professional, and so came to expect a reasonably good, low cost product. I have to say that I was really disappointed with these headphones.
Summary: Still use them now after 2 years of purchasing. Sizing makes a difference, very comfortable and completely block out any surrounding noise. unfortunately they do let out sound from whatever you are listening to.
Summary: These were ordered for my daughter who is happy with them but said the music does not come through them very loudly when used with her laptop, phone or iPod. This may be intentional to save kid's ear drums being damaged.
