Well guys. I believe I got a brain burn-in. I am ok now with Shure's SE535. Altough I still can see more soundstage in Bose's.   I listen mostly to heavy metal.   Anyway, thanks a lot for all the info.

Thanks for the tip. I already tried all the sleeves but will try them again. Maybe my emotions are biasing my judgement. Thanks. Any other information you guys can add?

Hello Guys,   I am new in the forum and came here because of my new Shure SE535 IEMS. I will be direct. When I was in Canada (I am from Brazil), I tried the Bose QC 15 in the store and was amazed by the crystal clear sound. I bought and honestly I am still very pleased with the sound.   ...
