Short answer: the Sony ULT Tower 7 for battery life and coverage, the Bose S1 Pro+ for mixing. The Tower 7’s claimed 30-hour battery beats the Bose’s 11 hours, its wheels make it easier to move and its 360-degree drivers fill a room, all for less at $548. The Bose counters with a 3-channel mixer with per-channel OLED displays and Auto EQ in a 14.3 lbs (6.5 kg) cabinet, a better fit for a performer than the Sony’s single mic/line jack.
This pits Sony’s Tower 7, a 360-degree consumer party speaker, against the Bose S1 Pro+, 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 Bose S1 Pro+ offers a 3-channel mixer with per-channel OLED displays for quick EQ/reverb adjustment, Auto EQ that adapts to cabinet orientation, and multiple angled placement positions, all at just 14.3 lbs (6.5 kg).
Choose the Tower 7 for longer claimed battery life, wheels for easier transport, immersive 360-degree party sound and a lower price: Its claimed 30h battery beats the Bose S1 Pro+’s 11h. 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. At $548 it also costs less.
Choose the Bose S1 Pro+ for true multi-channel mixing in the lightest cabinet here: Its independent-channel mixer with dedicated gain/EQ per input suits a performer or DJ better than the Tower 7’s single mic/line jack.
Buy the Sony ULT Tower 7 at $548 if you want a party speaker. Buy the Bose S1 Pro+ at $699 if you want a battery-powered PA speaker instead.
There is a real gap in water resistance: the Sony ULT Tower 7 at IPX4 (splashing) against the Bose S1 Pro+, which has no water resistance.
