I wish to buy a good quality set of headphones which i can use to listen to music while my kids are watching TV. Therefore, they shouldn't be too leaky. I have a decent system - Roksan Kandy amp and CD - and I prefer to listen to classical, acoustic, jazz, folk, low-fi. I dont need booming bass! I suppose I can spend up to £200. Are closed back headphones the best option and which are the best? I live in a rural community and so find it difficult to audition.
