Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Sony ULT Tower 5 ranks #5 of 39 party speakers by sound quality at $449.99; the Teufel Rockster Air ranks #11 of 14 battery-powered PA speakers by sound quality at -.
This pits Sony’s Tower 5, a compact consumer party speaker, against the Teufel Rockster Air, a performer-focused battery PA. The Tower 5 offers a 9-inch woofer with dual tweeters, a removable 20-hour battery, IPX4 splash resistance, 10-band EQ with ULT1/ULT2 modes, and RCA/XLR/USB-C inputs for DJ and karaoke use. The Teufel Rockster Air offers a claimed 30-hour battery, 115dB max SPL and XLR mic/instrument inputs with daisy-chain linking, though it is discontinued and was only ever sold in Europe.
Choose the Tower 5 for big-room output and app EQ modes and a lower price: Its ULT1/ULT2/EQ modes and compact footprint suit a living-room-to-backyard party speaker better than a performer-focused PA cabinet. At $449.99 it also costs less.
Choose the Teufel Rockster Air for dedicated instrument inputs and daisy-chain linking: Its claimed 30h battery beats the Tower 5’s 20h. It is discontinued, so check current stock and condition before buying.
Buy the Sony ULT Tower 5 at $449.99 if you want a party speaker. Buy the Teufel Rockster Air at - if you want a battery-powered PA speaker instead.
If sound quality matters at all to you, skip the Teufel Rockster Air. It ranks near the bottom of the 14 battery-powered PA speakers, so look higher up the list instead.
Battery life favors the Teufel Rockster Air: rated for 30 hours against 20 hours for the Sony ULT Tower 5.
If water resistance matters to you, the Sony ULT Tower 5 at IPX4 (splashing) holds up far better than the Teufel Rockster Air at no water resistance.

The Two Speakers In Full
Sony ULT Tower 5: $449.99 Amazon eBay
Pros: At $449.99, its 300W system with a 9-inch woofer delivers a notably capable party-speaker package: a removable 20-hour battery, IPX4 splash resistance, 10-band EQ and ULT1/ULT2 modes. AudioTribe’s first impressions praise its deeper bass and clearer sound than the JBL PartyBox Club 120; it also has USB-C and USB-A, RCA, balanced XLR and mic inputs for DJ and karaoke use.
Cons: It has a shorter 20-hour battery claim than the Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance. Its single-woofer, two-tweeter layout lacks the Tower 7’s 360-degree rear-driver array, and the reviewer describes the sound assessment as first impressions rather than a controlled measurement comparison.
