I was wondering if these headphones would be comparable to the Sennheiser headphones, they have a larger frequency range, they also have a higher sensitivity, aka signal to noise, from what I understand the higher the ratio, the less obtrusive. But then again they have 24 ohms of impedance, which I don't think interferes with quality.
