The Sony MDR-1A is really a fairly light-weight, extremely comfy full-size headset that provides audio that is enhanced more than the MDR-1R's, with much better definition in the bass with the midrange towards the treble. The headsets now sit in your neck properly (the ear cups rotate the correct path) and also you get two cables, 1 of that has an in-line distant for smart phones, together with a pleasant carrying pouch.
