Compact Bluetooth 5.4 speaker for mobile users

The Keransean E09B is a pocket-sized portable speaker built around Bluetooth 5.4 connectivity and a 5 W active driver. Its metal shell with a silicone cover weighs 81.2 g and includes a detachable lanyard for easy carrying. The integrated noise-reduction microphone supports clear voice calls during meetings or outdoor activities.

Bluetooth pairing and TWS expand the soundstage

Pair the speaker wirelessly with any Bluetooth device up to 10 meters away. True Wireless Stereo mode lets you link two E09B units for a wider stereo image without cables. The simple on-device buttons handle playback and call controls so no companion app is required for basic operation.

Twelve-hour battery sustains all-day playback

A full charge delivers up to 12 hours of continuous playtime at moderate volume. The 5 W amplifier maintains consistent output without thermal throttling during extended sessions. RGB LED lighting adds visual feedback while the 360-degree driver layout distributes sound evenly in every direction.
