Design and features:These earphones have very high sensitivity so they can provide satisfying volume levels when used with home audio equipment and even lower powered portable audio devices. The Nesta has an inline volume control that works with iPads and some iPod and iPhone models, plus an integrated microphone and music player function controls that are compatible with iPads, some iPods, and some iPhones and some other cellphones. The call connect/disconnect button can be used with some iPhones and some other cellphones. These earphones may not operate properly with some non-Apple/non-Android mobile devices or other audio equipment. This model comes with three pairs of ear pieces in various sizes and a carrying bag.
Sound quality: We found the Nesta 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 boomy and soft. Bass (as in bass drums, bass guitars, stand-up bass, etc.) has good impact and goes deep, but is boomy and somewhat prominent. The midrange (voices, guitars, horns, etc.) is fairly even but is somewhat hazy, a bit grainy, and somewhat overwhelmed by the bass. The treble (cymbals, the upper range of violins, etc.) is extended, but somewhat subdued and soft. While the sound has a decent sense of liveliness it is somewhat closed-in -- sound-wise it is somewhat obvious that you have something plugging up your ears.
Comfort: As typical of in-ear models we found that these earphones produce a sense of pressure in the ear canal opening might be uncomfortable for some. They fit and stay in place, but the sound quality is very dependent on proper placement.
