Design and features:These headphones have low sensitivity; so while they can provide satisfying volume levels when used with home audio equipment and higher powered portable audio devices, they may not be a good match for lower-powered portables. The Sine has a detachable 46-inch-long, standard audio cable and earcups that swivel to flat for ease of carrying and storage. It comes with a mini-plug-to-1/4-inch-plug adapter and carrying pouch, and is covered by a 36-month warranty on its planer magnetic drivers and 12-month warranty on its earpads, headband, and audio cable.
Sound quality: We found the Sine delivers sound quality that falls in the excellent range; while no pair of headphones is perfect, the sonic shortcomings of this model are minor. The overall sound can best be summarized as slightly thin and a bit washed out. Bass (as in bass drums, bass guitars, stand-up bass, etc.) has good definition and goes fairly deep, but is slightly subdued and has so-so impact. The midrange (voices, guitars, horns, etc.) is a touch hazy and lacks a bit of body. The treble (cymbals, the upper range of violins, etc.) is extended, but the lower- and mid-treble are slightly prominent and sizzly (sounds that should have a delicate shimmer have a sound reminiscent of bacon frying), while the upper treble is a bit subdued. While the sound has a good sense of liveliness, it is slightly closed-in -- sound-wise there is always a sense that you have something covering your ears.
Comfort: We found that these headphones produce a sense of moderately high pressure around the ears. They may feel heavy to some users, the ear pads might feel hot and/or sticky after prolonged use, and their over-the-ear fit may feel cramped for all except those with smaller ears. When wearing this model while walking, the vibrations from each foot step can be faintly heard through the headphones.
