Design and features:Although this home/studio-style over-ear model lacks active noise reduction, the closed design helps to reduce both outside noise and sound leaking out into your environment. The headphones have medium sensitivity so they can provide satisfying volume levels when used with home audio equipment and all but the lowest-powered portable audio devices. The PM-3 has earcups that swivel to flat for ease of carrying and storage, and comes with a detachable 119-inch standard audio cable, a mini-plug-to-1/4-inch-plug adapter, a detachable 47-inch long audio cable with built-in mic and call answer/music player control button for iPhone/iPod/iPad and smartphone use, and a carrying case.
Sound quality: The PM-3 delivers excellent sound quality, and It would be a good choice for the listener who won't be satisfied with anything less than top-notch music and movie soundtrack playback. The sound is best described as neutral (neither full nor lean) and pretty clean. While no headphone is perfect, the shortcomings of this model are minor. Bass (the tonal region that more or less covers bass drums, bass guitars, stand-up bass, etc.) has good impact and goes deep, but lacks a bit of detail. Midrange (the tonal range that more or less covers voices, guitars, horns, etc.) is fairly even and you can hear all but the finest detail, but there is a hint of haziness. Treble (the tonal range that covers cymbals, the upper range of violins, etc.) is slightly subdued compared to the rest of the tonal range, and the highest treble is a bit muted. The overall sound has a good sense of liveliness and is somewhat open (sound-wise it almost seems like you don't have anything covering your ears).
Comfort: We found that these headphones produce a sense of moderate pressure around the ears. The ear pads might feel hot and/or sticky after prolonged use.
