Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Sony ULT Tower 7 ranks #1 of 39 party speakers by sound quality at $649.99; the Teufel Rockster Air 2 ranks #5 of 14 battery-powered PA speakers by sound quality at $499.99.
This pits Sony’s Tower 7, a 360-degree consumer party speaker, against the Teufel Rockster Air 2, a performer-focused battery PA. The Tower 7 offers seven drivers for 360-degree sound, a claimed 30-hour battery, wheels, IPX4 splash resistance, 10-band EQ and a full RCA/XLR/USB-C/mic input section. The Teufel Rockster Air 2 offers a horn-loaded compression tweeter for more even off-axis coverage than a typical front-firing party speaker, a 58-hour claimed battery, and XLR mic/instrument inputs.
Choose the Tower 7 for wheels for easier transport and immersive 360-degree party sound: Its wheels also make it easier to roll between rooms or events. Its 360-degree drivers and ULT1/ULT2/EQ modes suit a living-room-to-backyard party speaker better than a performer-focused PA cabinet.
Choose the Teufel Rockster Air 2 for the longest claimed battery in the class and wider off-axis coverage: Its claimed 58h battery beats the Tower 7’s 30h. At $499.99 it also costs less.
Buy the Sony ULT Tower 7 ($649.99) for a party speaker; the Teufel Rockster Air 2 ($499.99) suits a battery-powered PA speaker instead.
If battery life is a priority, the Teufel Rockster Air 2 is rated for 58 hours versus 30 hours for the Sony ULT Tower 7.
Water resistance is not close: the Sony ULT Tower 7 is rated at IPX4 (splashing), well ahead of the Teufel Rockster Air 2 at no water resistance.

The Two Speakers In Full
Sony ULT Tower 7: $649.99 Amazon eBay
Pros: A compelling large-party value at $649.99: 420W output, an IPX4-rated 30-hour battery, 360-degree sound, wheels and four carry handles at 22.8kg. The full review praises its punchy, clean ULT1 bass, ULT2’s higher-output mode, simplified controls and unusually complete I/O: USB-C, USB-A, RCA, balanced XLR and mic input.
Cons: The reviewer notes that Auracast pairing is not backward-compatible with Sony’s older Party Connect speakers, and the hard-plastic corners lack protective rubber bumpers. IPX4 is splash resistance rather than full weatherproofing; the 30-hour claim requires lights off.

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.
