Short answer: the Bose S1 Pro if you want the most portable, professionally built option with a real onboard mixer; the Rockster Air 2 if you want more battery life and a lower price. These rank #13 and #16 out of 51 party-size speakers, at $499.99 and $699, with the Bose costing $199.01 more.
The S1 Pro is built more like professional PA gear in miniature. At 6.5 kg (14.3 lbs) it’s under half the Rockster Air 2’s weight, and it packs a genuine three-channel mixer - two mic/line channels plus a line/Bluetooth channel - along with auto-EQ that adjusts based on how it’s oriented, useful if you’re switching between upright and tilted-monitor placement. Our own notes rate its build quality highly and call the vocal reproduction crystal clear.
That refinement comes with real trade-offs at volume. The S1 Pro’s own notes say full-range music starts distorting above about two-thirds volume, and it has less deep bass than Electro-Voice’s Everse 8 - it’s better suited to voice amplification than as a music-first party speaker. It’s also discontinued, so it’s a secondary-market buy at this point.
The Rockster Air 2 is the bigger, longer-running, cheaper option. Its 58-hour battery dwarfs the S1 Pro’s 11, its larger 10” woofer gives it more low-end headroom for music, and it costs noticeably less. Both take XLR input for real microphones and instruments, and neither carries an IP rating.
Buy the S1 Pro if you want the more portable, professionally finished speaker with a built-in mixer, mainly for voice or moderate-volume use. Buy the Rockster Air 2 if you want to actually push music loud and not worry about battery for days.
There is a real battery-life gap here: the Teufel Rockster Air 2 is rated for 58 hours, the Bose S1 Pro+ only 11 hours.

The Two Speakers In Full
Teufel Rockster Air 2: $499.99 Amazon eBay
Pros: More consistent off-axis sound than the JBL Partybox 130, thanks to its single horn-loaded compression driver. Projects sound more evenly to the sides, unlike the JBL’s narrower front-firing dispersion. Cleaner instrument separation at high volume than the JBL Partybox 130, which turns anemic and loses bass at max volume despite its bass boost.
Cons: Bass isn’t as deep as the JBL Partybox 130’s boosted bass, though the JBL’s is boomy rather than truly deep. Bass and treble aren’t perfectly controlled at maximum volume - can sound hollow or too bright unless turned down from default. Not meaningfully louder than its 3-year-old predecessor, and the reviewer found the overall tuning a bit worse.

Bose S1 Pro+: $699.00 Amazon eBay
Pros: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. Three-channel mixer (2 XLR/quarter-inch combo mic-instrument + 1 line/Bluetooth), each with its own OLED display for quick treble/bass/reverb adjustment. Auto EQ adjusts sound based on orientation. Multiple angled surfaces for various positioning including tilted portrait mode, plus a line out to daisy-chain a second unit. Optional WT-XLR/WT-INST wireless transmitters dock, pair, and charge right in the speaker for a cable-free mic or instrument. Up to 11 hours battery life. Professional build quality. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage.
Cons: With full range music, it becomes distorted above ⅔ volume, and reviewers describe it as screeching at max volume. Better suited for voice amplification. Not as much deep bass as the Everse 8, midrange sounds reasonably balanced. Treble is pretty boosted. Not stereo. Designed for more loudness than deeper bass. Ports are fully exposed with no water resistance. Charges via a less common three-prong AC cable instead of the two-prong barrel cable most rivals use.
