Medium
The best medium size battery powered speaker with digital USB Audio input and the best sound quality with modern features is the JBL Charge 6 [Amazon] [Bhphotovideo]: $200
- Positives: Seems more neutral than the Charge 5. Flatter frequency response through the mids and treble as the Charge 5 was quite rolled off up high. Use this EQ from Joy/Oluv and turn down the lowest bass slider for the best sound quality. Oluv has even more paid EQs specifically for the GG and TL models indoors and outdoors here

Boombox
The best boombox size battery powered speaker with digital USB Audio input for deep bass that can get loud for a party but can still be carried by hand is the JBL Boombox 4 [Amazon] [Bhphotovideo]: $550
- Positives: Pretty insane output capability for the size.
- Negatives: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
