Design and features:The FitActive Air has an integrated microphone and built-in volume, music player function, and call connect/disconnect controls for use with Bluetooth paired devices. This model is claimed by the manufacturer to be water resistant and comes with two pairs of ear pieces of various sizes and a USB charging cable.
Sound quality: We found the FitActive Air delivers sound quality that falls in the fair range, meaning that it has sonic shortcomings that leave a lot to be desired when listening to music but don't rule it out for dialog and communication. The overall sound can best be summarized as bright and tinny. What little bass (as in bass drums, bass guitars, stand-up bass, etc.) it has is very subdued and does not go deep. The midrange (voices, guitars, horns, etc.) is thin, gritty, hazy, and is piercing at anything above a moderate volume. The treble (cymbals, the upper range of violins, etc.) is extended but prominent and sizzly - sounds that should have a delicate shimmer have a sound reminiscent of bacon frying. While the sound has a good sense of liveliness it is closed-in -- sound-wise it is obvious that you have something covering your ears.
Comfort: We found that these earphones fit and stay in place with no problems and that the ear bowl support ear pieces are very stable even with vigorous head movement.
