Short answer: the Teufel Rockster Air for battery life and volume, the Bose S1 Pro+ for size and clarity. The Rockster Air runs an exceptional 58 hours, 31 hours at full volume in ECO mode, with a user-replaceable battery and 112dB output, but its midrange is peaky and it distorts above half volume. The S1 Pro+ is extremely compact and light with crystal-clear audio, though full range music distorts it above two-thirds volume. The Teufel Rockster Air is discontinued; its replacement is the Teufel Rockster Air 2.
Buy the Bose S1 Pro+. It is rated higher for sound quality and still sold new, while the Teufel Rockster Air is discontinued.
If battery life is a priority, the Teufel Rockster Air is rated for 30 hours versus 11 hours for the Bose S1 Pro+.
