Short answer: the Teufel Rockster Cross for a neutral, vocal-forward sound, the Soundcore Motion X600 for its firmware fix. The Cross has a pretty neutral response and a larger mid/bass driver that makes it more vocal than the JBL Xtreme 4, though outdoor mode can sound harsh from a 4kHz peak and its bass is not as deep as the Xtreme 4. The X600’s firmware 4.2.9 is a big improvement, but its stock response is wavy, so use spatial mode.
Buy the Soundcore Motion X600. It is rated higher for sound quality than the Teufel Rockster Cross and costs less, so only choose the other one for a particular feature it does better.

Soundcore Motion X600: $150 Amazon B&H Photo Video eBay
Pros: Firmware 4.2.9 is a big improvement in sound quality over previous releases. Try this Oluv EQ for the best sound quality. Measured bass extension of 52Hz (-10dB).
Cons: Stock frequency response is wavy. Use spatial mode for best sound quality. Need a different EQ for each volume step. Dip in the upper bass around 120Hz. Rising frequency response, treble a little hot. Would be ranked around #20 without the Oluv EQ. Even with the Oluv EQ the bass isn’t very deep and the sound is still a little unnatural.

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.
