I really love these headphones, they are light weight, comfortable, and can be worn for hours without even knowing you are still wearing them. They do a great job at blocking out, outside noises, flight from Sydney to Hawaii, never heard a thing, and then used them to mow the lawn and totally blocked out the mower :) The sound quality is great, has deep base and can really hear the true quality of the music. I would recommend these as a great christmas gift for anyone :)
