Soundcore Motion X600 vs Teufel Rockster Cross

Last updated: August 19, 2026

Short answer: the Soundcore Motion X600. It ranks #19 of 77 large speakers by sound quality at $150; the Teufel Rockster Cross ranks #21 and costs $199.99, so there is not much of a tradeoff to weigh.

What the Soundcore Motion X600 offers: Firmware 4.2.9 is a big improvement in sound quality over previous releases. The catch: Stock frequency response is wavy. Use spatial mode for best sound quality.

The case for the Teufel Rockster Cross: 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. Watch for: 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.

Buy the Soundcore Motion X600. It ranks higher for sound quality than the Teufel Rockster Cross and costs less, so there is no real case for the other one.

Soundcore Motion X600 ranking card

Pros: Firmware 4.2.9 is a big improvement in sound quality over previous releases. Try this Oluv EQ for the best sound quality

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: $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.
