Really fantastic sound - I had a portable headphones not have expected. Differentiated sound, slightly raised bass range, the sounds punchy and tired. I had only the Porta Pro and - tried unfortunately only days later the Sporta Pro. I felt as equivalent (although, as I said, a direct comparison is missing). That's lifted the bass range, which may interfere with that necessarily require a linear reproduction, but it sounds with rich bass just great. Also the comfort is very good. Two foam nubs above the ear cups ensure that the pressure on the temples and only in gerimgem extent be applied to the ears.
