JBL Xtreme 4: $380 Amazon Bhphotovideo

JBL Xtreme 4 ranking card

Pros: Removable battery. Slightly deeper bass than Xtreme 3. Use this EQ for the best sound quality.

Cons: High priced. Some bass boost. Dip in the upper bass to midrange makes it sound strange which cannot be EQd out. Some upper mids and treble boost at high levels.
