I'm really torn between the SE-535 CL Westone 4R and UE900 The UE900 is the most expensive option for me right now (The 535 + Westone can be had for much cheaper. Specifically the 4R). I currently have the SE-215. My ears are really sensitive to treble/sibalance.
For the price, I'm thinking the Westone 4R sounds like my best bet. But I'm also afraid that it's a boring headphone (when I hear flat/neutral, I think bland). Then again, I love the SE-215, and I think those have a similiar sound?
Yes, you should like the Westone 4R since it sounds great with or without amplification, depends on the Tips being used.
