Summary: I recently bought a pair of RS2e headphones, stepping up in price from the SR325e model with its lower spec and heavier aluminium casing. My reference point for comparison of the sound quality is against Sennheiser's HD650, which are a foundation of my headphone stable.
Pros: Intimacy, sharpness and clarity of sound - outstanding for acoustic and vocal music. Visually unique, an impactful pair of headphones.
Cons: Horribly uncomfortable ear pads. Sharpness of the sound is an acquired taste.
