What the JBL Xtreme 3 gets right: Better treble and deeper bass than the Xtreme 2. More balanced sounding than the Xtreme 4. The catch: Boosted bass. Not as deep bass as better speakers. Not as balanced as better speakers.

What the Teufel Rockster Cross offers: Pretty neutral frequency response. More vocal/midrange-focused than the JBL Xtreme 4, thanks to a larger mid/bass driver - better suited to rock and jazz.

Teufel Rockster Cross: $199.99 Amazon

Teufel Rockster Cross ranking card

Pros: Pretty neutral frequency response. More vocal/midrange-focused than the JBL Xtreme 4, thanks to a larger mid/bass driver - better suited to rock and jazz. Nicer upper-bass detail than the JBL Xtreme 4. Punchy, well-controlled bass that suits rock music, unlike the Soundcore Boom 2 Plus’s overboosted, uncontrolled bass even at stock tuning. Clear, detailed audio with good vocal presence and solid Bluetooth codec support even a couple years after release.

Cons: Outdoor mode can sound somewhat harsh due to the 4khz peak. Not as deep or full-sounding in the bass as the JBL Xtreme 4.
