Short answer: the Teufel Rockster Cross if sound quality matters most, the Zealot S67 if price matters most. The Teufel Rockster Cross ranks #21 of 78 large speakers at $199.99. The Zealot S67 ranks #77 at $70.94, $129.05 cheaper.
What the Zealot S67 offers: It offers a lot of practical hardware for a 2.4kg budget speaker: IPX6 water resistance, USB-C charging, aux and microSD playback, speakerphone, a claimed 20-hour battery and TWS pairing for a second unit. The large enclosure and dual-driver/passive-radiator layout can provide useful party-level volume. Watch for: Sound quality is the catch. Independent reviewer comparisons report obvious distortion once volume rises past roughly halfway, little true deep bass, and a rolled-off, low-detail treble. There is no app or real EQ to correct that balance, so its long feature list does not make it a good pick for attentive music listening.
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. 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. 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 Zealot S67 if the price is the priority over sound quality, or the Teufel Rockster Cross if sound quality is the priority over the price.
If sound quality matters at all to you, skip the Zealot S67. It ranks near the bottom of the 78 large speakers, so look higher up the list instead.
