I just received the Shure 535's today. It sounds great in terms of clarity, and midrange voice comes thru very easily. I'm quite dissappointed in the warmth, and the bass response though. I've tried all the sleeves, and found the ones that fits best, but still it doesn't sound to my liking. I listen to such a broad variety of music, it's not going to make much sense to list them all.
I have read many threads on here praising the Shure 535's in many of the attributes I was looking for in an IEM, is why I chose them. I have not tested any IEM's except for owning UE 500's. I assumed that the 535's and others in it's class would easily outperform the UE 500's in bass response. I was wrong about that.
So, I've heard some switching to the Klipsch X10's, or Westone 3 & 4's... I'm not even sure this will surpass the UE 500's bass response?
Any other suggestions?
I've tested it on my iPhone 3GS w/ Bass Booster EQ, but also have a Cowon D2 I'll will be using.
