Ultimate Ears Everboom: $149.99 Amazon eBay
Pros: Ultimate Ears Everboom uses 2x 56.6mm x 56.2mm fullrange transducers + 2x passive radiators. Its 949 g, claimed 20 hours (Manufacturer specified) battery life, IP67 protection, aux input and mono playback make it a practical option for its intended room or portable use.
Cons: Careful placement and volume setting remain important for balanced sound. Warm tuning with an upper-bass boost and rolled-off treble, and the bass does not go very deep.
