It combines a minimalist circular design with practical connectivity: Bluetooth A2DP for wireless audio streaming, a microSD card slot compatible with microSD/SDHC/SDXC up to 128 GB, an AUX input for wired sources and a built-in FM tuner with memory for up to 60 stations. The speaker delivers 2 x 5 W RMS (10 W RMS total) output and includes a 2200 mAh rechargeable battery that provides approximately 5–7 hours of playback. A rear base supports vertical placement and a micro-USB port is used for charging.
