The Emberton III is the long-haul pick. Marshall rates it for more than 32 hours of playtime, the longest figure among the speakers we compared, and a 20-minute charge adds 6 hours, with a full recharge taking 2 hours. The body is small, 160 mm wide and 0.67 kg, with an IP67 rating that lets it sit in 1 m of water for up to 30 minutes. Sound comes from a 2X38 W Class D amplifier, a 2-inch full range driver and two passive radiators, tuned for what Marshall calls True Stereophonic 360-degree sound. Bluetooth 5.3 LE supports multipoint, and Marshall says the hardware is ready for Auracast audio sharing. A built-in microphone handles calls. Marshall also sells spare parts and documents user-replaceable components, which helps it last. The trade-offs: the 65 Hz low end reflects its size, and $179.99 is a step above the Beats Pill.
