Soundcore 2: $29.99 Amazon eBay
Newer model: the Soundcore 3, ranked higher, rated 3.4/5.
Pros: Soundcore 2 uses 2x 38mm fullrange. Its 318 g, claimed 24 hours (Manufacturer specified) battery life, IPX7 protection, aux input and stereo playback make it a practical option for its intended room or portable use.
Cons: Its 70Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment.
