The Hercules Outdoor Bluetooth Speaker ($82) was built for adventure, yet still packs the muscle required for quality sound. An integrated lithium ion battery and a built-in microphone provide up to 10 hours of continuous playing time and hands-free calling, while a pair of wideband drivers and a passive bass driver deliver crystal clear audio.
The speaker’s internal components are protected by a water and dust-resistant housing, which includes shock-resistant rubber end pieces and a double protective grille over the drivers.
