Bose S1 Pro vs Teufel Rockster Air

Last updated: September 2, 2026

Short answer: the Bose S1 Pro+. It ranks #16 of 51 party speakers by sound quality; the Teufel Rockster Air ranks #28.

What the Bose S1 Pro offers: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. The catch: With full range music, it becomes distorted above ⅔ volume. Better suited for voice amplification.

The case for the Teufel Rockster Air: Exceptional 58-hour battery (31 hours at full volume with ECO mode). User-replaceable battery adds real longevity. 112dB loud like live rock concert. The tradeoff: Peaky midrange, not very natural sounding. Starts to get distorted above half volume.

Buy the Bose S1 Pro+ if sound quality is the priority over the price, or the Teufel Rockster Air if the price is the priority over sound quality.

If battery life is a priority, the Teufel Rockster Air is rated for 30 hours versus 11 hours for the Bose S1 Pro+.

The Two Speakers In Full

Bose S1 Pro+: $699.00 Amazon eBay

Bose S1 Pro+ ranking card

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.
