Hello, I am pro keyboardist-singer and I use the headset in ear Shure E530 since August 2010, and only happiness.
The only model I used before the E530 is the Sennheiser IE4 came with my Sennheiser EW300 IEM G2 system, and there is no comparison. With the Sennheiser: almost no bass, midrange very dug acute aggressive little available power (distortion appears very quickly), very average insulation. With the Shure, it's like going from the 2CV to a Rolls. Everything is here and only happiness.
Particularities +: - very good insulation
- Clear sound
- Deep, rich bass and fine treble
- No distortion
Value for money? Okay, it is not given, but frankly, there's something for his money.
If I were to give a rating for this product, I give a 9 (ie d: excellent)
