Design and features:The earphones have high sensitivity so they can provide satisfying volume levels when used with lower-powered portable audio devices. This model comes with four pairs of ear pieces of various sizes and a carrying bag.
Sound quality: We found the Y23 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 overall sound can best be summarized as slightly bassy and a bit lean. Bass (as in bass drums, bass guitars, stand-up bass, etc.) has good impact and goes fairly deep, but is a bit prominent and boomy. The midrange (voices, guitars, horns, etc.) is a touch lean and slightly grainy. The treble (cymbals, the upper range of violins, etc.) is extended, but somewhat smeared (sounds that should have a delicate shimmer sound blurred) and the upper treble is muted. The sound has a good sense of liveliness and is somewhat open -- sound-wise it almost seems like you don't have anything plugging up your ears.
Comfort: We found that these earphones fit and stay in place with no problems, but they produce a sense of pressure in the ear opening that might be uncomfortable for some.
