Short answer: the Teufel Rockster Air for instrument inputs and daisy-chain linking, the Sony ULT Tower 7 for buying one today. The Teufel matches a 30-hour battery claim with 115dB max SPL and XLR mic/instrument inputs that can be daisy-chained, but it is discontinued and was only ever sold in Europe. The Tower 7 rolls on wheels, uses a 360-degree seven-driver layout and remains available. The Teufel Rockster Air is discontinued; its replacement is the Teufel Rockster Air 2.
This pits Sony’s Tower 7, a 360-degree consumer party speaker, against the Teufel Rockster Air, 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 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 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 for dedicated instrument inputs and daisy-chain linking: At $500 it also costs less. It is discontinued, so check current stock and condition before buying.
Buy the Sony ULT Tower 7 if you want a party speaker. Buy the Teufel Rockster Air if you want a battery-powered PA speaker instead.
If water resistance matters to you, the Sony ULT Tower 7 at IPX4 (splashing) holds up far better than the Teufel Rockster Air at no water resistance.
