So the "Walkman" inventor Sony I had expected more, frankly. I do not use plugs and strap headphones, and who likes to listen to loud, the custom headphones with a very high efficiency ("sensitivity"). Behringer PX was much too quiet, Koss Porta Pro is indeed loud, but I got myself to NEN small amplifier (FiiO E06). Then it is loud enough, does not make it more manageable. Otherwise, the thing does not make a particularly strong impression, the first few weeks (incl. Once on the asphalt fall) but it has survived.
