Short answer: the JBL Xtreme 3 for bass depth, the Teufel Rockster Cross for a neutral, midrange-focused tuning. The Xtreme 3 has better treble and deeper bass than the Xtreme 2 and more balanced sound than the Xtreme 4, though its bass is boosted. The Rockster Cross is neutral and more vocal-focused than the Xtreme 4, better for rock and jazz, though Outdoor mode can sound harsh from a 4kHz peak and its bass is not as deep as the Xtreme 4’s.
Buy the JBL Xtreme 3. It is rated higher for sound quality, and saving $19.96 with the Teufel Rockster Cross does not make up for the sound-quality gap.

Teufel Rockster Cross: $249.99 Amazon eBay
Newer model: the Teufel Rockster Cross 2, ranked higher, rated 4.2/5.
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. Measured bass extension of 51Hz (-10dB).
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.
