Excellent Sound, Fragile Design. I Had Been Using These Heads For About Two Years Back In 2004-2005 Before They Got Stolen With All Of My Equipment. It Was In St.-Petersburg, Russia. The Main Reason Why I Bought These Was Their Size. I Was Looking For Something I Could Use For Djing But, At The Same Time, Also Use In Everyday Life Without Looking Like An Alien. And It Never Gave Me Any Reasons To Regret! Perfect Clean Sound, Nothing Else! The Phone Cup Is Not Actually Closing Your Ear, So You Are Still Able To Hear Other Sounds, Which Was Pretty Convenient For Me When Playing In A Club. When I Needed To Hear The Monitor, I Was Just Moving The Cup A Bit Off The Ear. There Is A Weak Point They Have Though - These Heads Are Very Fragile. Once I Let Another Dj Use My Heads Just For One Night. He Returned Them Broken At The Joint Of The Cup And A Handle. May Be Those Who Are Considering Buying Them Should Have A Look At 7505 As They Are Much Stronger And Foldable.
