Ultra-Light Portable Audio

The Keransean E09B is a pocket-sized Bluetooth 5.4 speaker weighing 81.2 g and wrapped in a metal shell with a silicone cover. Its detachable lanyard lets you clip it to a bag for travel, hiking or casual outdoor listening. A built-in noise-reduction microphone handles clear voice calls alongside music playback.

Bluetooth 5.4 Range and Pairing Limits

Wireless range reaches 10 meters in open space, and the 2.0 channel output delivers 360° stereo sound from a single unit. TWS pairing allows two E09B speakers to combine for wider stereo separation, but the link remains bound to the Bluetooth 5.4 specification. No wired input or multi-room protocol is provided.

Five Watts and Twelve Hours Runtime

Total output power is 5 watts from an active amplifier, and the internal battery sustains up to 12 hours of playtime per charge. Buyers who need louder output for large spaces or longer runtime without recharging should look at larger portable systems.
