hi i have had some audio techica ath-sj5s for years now and never had the money to upgrade. i got a voucher for amazon.co.uk and the goldring and senn. are both about £40 (voucher amount). is there a clear winner? i know they are open and closed cans but that wont matter. i also noticed that my current headphones are more then £50 on amazon but im sure price is meaningless especially on that site. thanks for any advice.
