The Bose SoundLink Revolve Speaker ($200) is their first to incorporate 360-degree sound. Highly portable, it overcomes its small body by using a downward-facing transducer, dual passive radiators, and a carefully-angled acoustic deflector to transmit full sound wherever it’s placed. Its rechargeable battery lasts for 12 hours per charge, Bluetooth frees you from the tyranny of wires, and the water-resistant body means it’s as welcome at the pool as it is on the patio. Also available in a larger, more robust “+” version for $100 more.
