For the past 2 years I have been listening to Dubstep and Drum & Bass. I have owned a pair of Sony EX-500LP earphones for 6 months, but today they have broke so I am looking for a replacement. I was happy with my 500's after the burn-in period; In a quiet environment and "Bass Booster" EQ selected on my iPod they were heavy on the bass, whilst remaining balanced in the mids and highs. My friend owns the V-Moda Bass frequency earphones, I tried them out and they sounded identical to mine.
So, I am now in search of similar IEMs; heavy on the bass, but having a good balance of mids and highs that aren't recessed or hidden behind the bass. My budget is £50 maximum and this is for a pair of portable earphones, not headphones. They will be used in conjunction with an iPod Touch as the source, and I will use them on the bus to and from College, so noise isolation is quite important. I'd like to add that I live in the UK and I can purchase from sites such as Play and Amazon.
Help is much appreciated
