Tanga offers the JBL OnBeat Micro Speaker Dock with Lightning Connector for iPhone 5 for $39.99 with free shipping. That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's a current price low by $8.) It features a 110Hz to 20kHz frequency response, dock charger, USB for compatibility with other devices, and two full-range transducers. It's designed for use with the iPhone 5, 5c, 5s, 5th-generation iPod touch, and 7th-generation iPod nano.
