Hello forum, I am new here and I need some experience, help and thoughts about IEMs. Firstly I have used Creative EP-630 five years ago One year ago, I wanted to change it to Meelectronics M6. I have been using this over one year. But It is getting to hard wear them. Because its cable must cross back of my ears. So, I need a new earphone as normal wear. My music taste is Rock, Metal, Pop and Blues. I interest in Brainwavz earphones now very very confused which model is the best for me. M1, M2 and M3 are old models I think. M4, M5 and R1 are newer than others. I am interested in R1 beause of two spearkers. But I think its build quality is not very well because of plastic body. Last word, which is the best one for me? On the other hand you can recommend other brands and models for me at max 50-60 USD Also If you can choose best in the survery below, I would be happy for it. Thanks a lot.
