Soundcore Boom 2 vs Teufel Rockster Cross

Last updated: October 1, 2026

Short answer: the Rockster Cross for a neutral, midrange-focused sound; the Boom 2 for deeper bass. The Teufel has a pretty neutral frequency response and, thanks to a larger mid/bass driver, is more vocal-focused than a JBL Xtreme 4 and better suited to rock and jazz, though Outdoor mode can sound harsh from a 4kHz peak. The Boom 2 has pretty deep bass for the size, but only its tweeters give stereo.

Soundcore Boom 2 ranking card

Older model: the Soundcore Motion Boom (ranked lower, rated 4.5/5).

Pros: Pretty deep bass for the size. Cool lights in the side passive radiators. For the best sound quality use Oluv’s EQ or Alan Ross’s EQ. With the stock tuning, this speaker would rank around #24, due to the boosted bass and rising treble. Measured bass extension of 47Hz (-10dB).

Cons: Only a single midrange driver, so you only get stereo for the tweeters. Sound processing issues with inconsistent bass notes that disappear at low levels like the Soundcore Boom and Soundcore Boost, not great for listening at low levels. Quite bass heavy with BassUp turned on, which is best left off. A little bit of a bright tuning in the treble, about +5db.

Teufel Rockster Cross: $249.99 Amazon eBay

Teufel Rockster Cross ranking card

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.
