Design and features:The True Evo Wireless Earbuds have an integrated microphone and music player and call connect/disconnect controls for paired Bluetooth devices. They also support Apple Siri and Google Assistant digital voice assistants when used with Bluetooth devices that have those capabilities. This model is claimed by the manufacturer to be water resistant and comes with ten pairs of ear pieces in various sizes and types, three pairs of ear bowl supports in various sizes, a USB charging cable, a charging cradle/recharger battery/carrying case that the manufacturer claims can be used to recharge the earphone batteries up to four times between its own charges and that can be recharged wirelessly with an optional Qi charging pad, and a carrying pouch.
Sound quality: We found the True Evo Wireless Earbuds delivers sound quality that falls in the Good range - it reproduces music and voice reasonably well despite the obvious shortcomings in its sound (It actually would have scored in the very good range but the excessive bass dropped the score to good). The overall sound can best be summarized as very bassy. Bass (as in bass drums, bass guitars, stand-up bass, etc.) goes deep, but is prominent, excessively boomy, and has exaggerated impact. The midrange (voices, guitars, horns, etc.) is fairly even, but slightly grainy and, with some program material, can be overwhelmed by the bass. The treble (cymbals, the upper range of violins, etc.) is fairly extended. 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: 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 are very stable even during vigorous head movements. Some uses might find pushing on the controls to actuate the functions drives the earphone further into the ear bowl and/or canal and causes ear discomfort.
