Ultimate Ears Miniroll: $49.99 Amazon eBay
Older model: the Ultimate Ears Roll 2 (rated 2.2/5).
Pros: Ultimate Ears Miniroll uses 45.6mm active with passive radiator. Its 279 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection, up to 83dB and mono playback make it a practical option for its intended room or portable use. Good clarity and detail in the mids and highs, with a warmer balance than most speakers its size.
Cons: There is no companion app. No EQ adjustment. Bass does not reach as deep as the best-rated speakers.
