5 Fantastic!!Miniramierez | 10/07/2012 | See all Miniramierez's reviews (1)I've been buying Sennheiser CX300's for the past few years now and decided to go with something new as my CX300's died. After a quick check on whathifi, I thought I'd give the e10's a go. I haven't been disappointed. They sound amazing, the bass is very punchy, the mids and treble are very crisp, almost every note is heard.While I was awaiting delivery of these buds, I was using a friends Bose IE2's which cost around 100 quid, the Soundmagics are, in my opinion, far superior, at a fraction of the price.If anyone is considering buying these, I would recommend that before you use them, plug them into whatever you plan on using them with and run them at full volume for about 3 hours to break them in, I do this for every set of headphones I buy and you'll definitely notice a difference. Also, I would recommend buying t400 comply foam tips for greater outside noise reduction, plus, the foam tips are a lot more comfortable.
