JBL Xtreme 4: $380 Amazon Bhphotovideo
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.

Cons: Doesn’t get very loud compared to other speakers in this class. Short battery life. Pretty heavy. Many say the S67 has deeper bass, but also gets more distorted
