Rockster Air 2 has more even off-axis sound and a much longer battery, but costs nearly four times as much as the Onn Large Party gen 2. They rank 19 of 51 and 13 of 51.
Rockster Air 2’s single horn-loaded compression driver gives more consistent off-axis sound and cleaner separation at volume than rivals like the JBL Partybox 130, with a 58-hour battery, though bass doesn’t reach as deep and there’s no app or EQ.
Onn Large Party gen 2 costs far less with its own karaoke mic/guitar inputs and wheels, though Consumer Reports found its bass boomy and treble smeared.
Buy the Teufel Rockster Air 2 if even dispersion and a long battery matter and your budget allows. Buy the Onn Large Party gen 2 for a fraction of the cost.
Battery life favors the Teufel Rockster Air 2: rated for 58 hours against 12 hours for the Onn Large Party gen 2.
Water resistance is not close: the Onn Large Party gen 2 is rated at IPX4 (splashing), well ahead of the Teufel Rockster Air 2 at no water resistance.

The Two Speakers In Full
Onn Large Party gen 2: $129 Walmart eBay
Pros: A remarkably full-featured, manageable 9.5kg party speaker: wheels and handle, FM radio, aux, USB-A charging, mic and guitar inputs with karaoke echo, and Party Sync. Independent testing confirms bass with real impact and enough output for a large room; it is a clear improvement over the Gen 1 for low-end weight.
Cons: The low price shows in the refinement. Consumer Reports found boomy bass, hazy/grainy mids, a prominent smeared treble and a narrow, two-dimensional soundfield; it also notes distortion or other audio issues. There is no app or EQ to tame the tuning, and IPX4 only covers splashes rather than rain or immersion.

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.
