Design and features:The Liberty 2 Pro has integrated microphones, and volume, music player, and call connect/disconnect controls for paired Bluetooth devices. Either earpiece can be used alone for one ear monitoring of Bluetooth streamed audio and telephone communications, and the Liberty 2 Pro supports Apple Siri and other unspecified digital voice assistants when used with Bluetooth devices that have those features. This model comes with seven pairs of ear pieces in various types and sizes, three pairs of earbowl supports in various sizes, a USB charging cable, and a charging cradle/recharger battery/carrying case that the manufacturer claims can be used to recharge the earphone batteries approximately 3 times between its own charges. The free Soundcore app for Apple and Android mobile devices can be used to customize the function of the earphones' controls, adjust the sound based on the user's hearing profile, provide different tonal balance settings, and update the earphones' firmware.
Sound quality: We found the Liberty 2 Pro 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 be summarized as bassy and somewhat sizzly. In the "Soundcore Signature" EQ setting (the manufacturer recommended and default EQ setting) the bass (as in bass drums, bass guitars, stand-up bass, etc.) goes deep, but is prominent and boomy, has excessive impact, and, depending on the program material, can overwhelm the midrange. The midrange (voices, guitars, horns, etc.) is a touch thin, hazy, and etched (a bit more sharply outlined then it should be), and a bit grainy. The treble (cymbals, the upper range of violins, etc.) is fairly extended but is somewhat prominent and sizzly (sounds that should have a delicate shimmer have a sound reminiscent of bacon frying). This model does a decent job of recovering the room ambience of a recording (the sense of the acoustic space in which the audio program that's being listened to was recorded). The sound also has a decent sense of liveliness and is somewhat open--sound-wise it almost seems like you don't have anything plugging up your ears. The other Soundcore app EQ settings and the HearID app feature had a noticeable effect on the sound.
Comfort: As typical of in-ear models they produce a sense of pressure in the ear canal opening might be uncomfortable for some. Users with small ear bowls might find that the earphone body does not fit completely in their earbowl and that the earphones are mostly held in place by the section of the earphone that is inserted in the ear canal; they stay in place with no problem for casual use, and can be made to feel secure during vigorous head movements but it would take a lot fiddling with the earbowl supports to get them seated. Users with medium and large sized ear bowls will probably find that this model stays in place with no problems for casual use and that they are very stable even during vigorous head movement.
