Portability, imaging and comfort are stellar on this headphone. I've always been a sennheiser fan and have been looking for the experience thatI had when I first listened to the HD414's. Having recently aquired a reissue of the HD414 I can compare the AKG's and the sennheisers's andthe AKG's win hands down, in particular in the imaging and bass. Sennheiser wins in comfort and timeless design. Highly recommended headphone, for a little over $30.00 (!!!!)
