Short answer: the Teufel Rockster Air 2 for battery life and off-axis coverage, the Sony ULT Tower 5 for price. The Teufel claims 58 hours of playback and uses a horn-loaded compression tweeter for more even off-axis coverage than a typical front-firing party speaker. The Tower 5’s claimed 20-hour battery is far shorter, but at $348 it costs less and still offers ULT1/ULT2 modes, 10-band EQ and RCA/XLR/USB-C.
This pits Sony’s Tower 5, a compact consumer party speaker, against the Teufel Rockster Air 2, 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 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 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 $348 it also costs less.
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 5’s 20h.
Buy the Sony ULT Tower 5 ($348) for a party speaker; the Teufel Rockster Air 2 ($499.99) suits a battery-powered PA speaker instead.
If water resistance matters to you, the Sony ULT Tower 5 at IPX4 (splashing) holds up far better than the Teufel Rockster Air 2 at no water resistance.
