Sound quality: We found the ATH-SQ1TW delivers sound quality that falls in the very good range - it reproduces music and voice very well although it does have some noticeable sonic quirks. The bass (as in bass drums, bass guitars, stand-up bass, etc.) has good impact and goes deep, but is a bit prominent and boomy. The midrange (voices, guitars, horns, etc.) is even, but somewhat grainy and etched (a bit more sharply outlined then it should be) and a bit hazy. The treble (cymbals, the upper range of violins, etc.) is extended, but is somewhat prominent and sizzly, and a bit smeared. The sound also has a good sense of liveliness and is open--sound-wise it seems like you don't have anything plugging up your ears and does a decent job of recovering room ambience. Mixed character - warmish bass, neutral midrange, and coolish treble, etc. The overall sound can best be summarized as a bit bassy, and somewhat grainy and a bit "bright".
Comfort: As typical of in-ear models they produce a sense of pressure in the ear canal opening might be uncomfortable for some. Users with small earbowls might find that the earphone body feels a bit bulky in their earbowl and that they stick out too far and feel like they may lever out of place and are mostly held in place by the section of the earphone that is inserted in the ear canal, but that they will stay in place during casual use and are stable even during fairly vigorous head movement. Users with medium and larger sized ear bowls will probably find that this model stays in place with no problems for casual use and that they are stable even during fairly vigorous head movement. Incidental contact with the touch controls can cause unintentional volume level changes, playing, pausing, or track skipping.
