Design and features:The PA-01 has an integrated microphone and music player and call connect/disconnect controls for paired Bluetooth devices. This model is claimed by the manufacturer to be water resistant and comes with three pairs of ear pieces in various sizes, a USB charging cable, and a charging cradle/recharger battery/carrying case.
Sound quality: We found the PA-01 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 slightly fuzzy. Bass (as in bass drums, bass guitars, stand-up bass, etc.) has good impact and goes fairly deep. The midrange (voices, guitars, horns, etc.) is fairly even, but is somewhat hazy and grainy. The treble (cymbals, the upper range of violins, etc.) is slightly smeared (sounds that should have a delicate shimmer sound blurred) and the upper treble is muted. Throughout the entire tonal range there is a pervasive slightly staticy quality that is especially apparent on sibilant vocals. While the sound has a good sense of liveliness it is somewhat closed-in (sound-wise it is somewhat obvious that you have something plugging your ears).
Comfort: As typical of in-ear models they produce a sense of pressure in the ear canal opening might be uncomfortable for some. They fit and stay in place with no problems, and the ear bowl support earpieces make the fit very stable even during vigorous head movements.
