Short answer: the Teufel Rockster Air for inputs and battery, the Sony ULT Tower 5 for buying one today. The Teufel claims a 30-hour battery, 115dB max SPL and XLR mic/instrument inputs with daisy-chain linking, beating the Tower 5’s claimed 20-hour battery. But it was only ever sold in Europe and is now discontinued, while the Tower 5 remains a compact app-EQ party speaker with 10-band EQ and RCA/XLR/USB-C. The Teufel Rockster Air is discontinued; its replacement is the Teufel Rockster Air 2.
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 $348 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 for a party speaker, or the Teufel Rockster Air for 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 at no water resistance.
