I'm traveling in next week and decided to order a set of the RE-400s. My current IEMa are a set of Sennheiser CX-880s (that replaced my old, beloved, and lost Shure EC3s). These things are ridiculously finicky, very microphonic and I hate the integrated volume. It's very noisy and sensitive. I'm not very pleased with the headphones and felt like a massive downgrade from my older Shure EC3s.
I was on the fence between the Shure 215s and the RE-400s, but pulled the trigger based on HiFiMANs reputation.
So my question is, does anyone have any insight to how the RE-400s match up against the Shure 215 or the Sennheiser CX-880?
