The Shure 535 noise isolating earphones are the best on the market for you audiophiles out there. They have Triple High Definition Micro drivers which are composed of 2 woofers and a dedicated tweeter. This gives the Shure 535's the best all round sound. We found whilst using these headphones that they were perfect for every occasion. There perfect for running and also personal monitoring if you're a musician. Whilst at the same time perfect for everyday use! The Shure 535's come with a detachable Kevlar reinforced cable which means that if the cable gets damaged then you don't have to replace the whole set! Although a replacement lead will set you back around £60!! Although these headphones aren't the cheapest at around £269.00 the richness, definition and clarity will make you wonder why you haven't bought them sooner! The headphones don't fit into your ears like any normal pair of headphones they wrap around the back of your ear meaning that you don't have a cable dangling all over the place! They also come with a handy carry case, jack adapter and various sized in ear foam sleeves. Overall we were pleasantly surprised with the quality of both the sound and the item itself. For anyone who truly cares about sound and music these are definitely the headphones for you!
