Summary: I bought these as an upgrade for my Shure SE 102s. The difference is incredible with a depth and richness of sound that takes these to s different level. I use them with an IAudion I7, choosing this MP3 player because of the better sound quality and greater possibility to personalise the sound compared to Ipods etc. I agree with the reviews in that they are a tad impractical although in the gym I still use my Shures.
Summary: First I have to say that I have tried many earphones. I have couple of pretty good ones, but I have never been satisfied, until now. Yes these earphones are phenomenal for me! I never thought that mp3 music can play this good! I have a portable headphone amp and maybe without that there wouldn't be so much differences between headphones. The size is too big and heavy to use in any sports. I got these for 140eur and they are quite expensive,but worth the money.
Pros: Very good, deep bass performance and good highs too.
Cons: They are maybe too open, i mean the music is too loud to those sitting next to you in public transport.
