Sound quality: soundcore's Rave Neo 2 had decent overall sound quality - this model reproduces music and dialog reasonably well despite the obvious shortcomings in its sound. With the soundcore app Custom EQ set to produce the most even tonal balance bass has good impact and goes fairly deep but is somewhat tubby and a bit to somewhat prominent depending on the program material. Midrange is fairly even, but is somewhat grainy and hazy, and a bit muffled. Treble is fairly extended but is somewhat subdued, a bit smeared, and sizzly, an the lower treble is muted. Does a so-so job of recovering room ambience and is congested. When two units are used to form a stereo pair the sound stage can be made wider depending on placement. There was no significant difference between Bluetooth, wired and USB sound quality. Provides a decent volume level in a large sized room.
