Recently I bought a Sony MDR-EX600, the first IEM I ever bought. Before this I had been using all the earbuds which came with my blackberry or ipod/iphone. I honestly thought the EX600 would give me that WOW factor. Surprisingly it didn't happen. In fact, I feel so good listening to my classical music with the headset (shown in the photo below) which came with my old blackberry.
This makes me wondering whether perception to the sound is very subjective or these expensive IEM's are overpriced/overhyped. I hope this will not offend anybody as I don't know anything about sound or even understand the terms frequently mentioned on this forum.
