Acoustic Sound Design via Amazon offers the JBL Pulse 2 Portable Bluetooth Speaker in Black for $79.95 with free shipping. That's $15 under last week's mention and the lowest price we've seen for a new unit. (It's the best deal now by $20.) This splashproof speaker features Bluetooth 4.1, an interactive multi-LED light show, 85Hz to 20kHz frequency response, microphone, and built-in rechargeable Li-ion battery with up to 10 hours of music per charge.
