Tell your tech-savvy birders that birdJam has a new TravelSound i80 Speaker for third-generation Nano iPods (4GB or 8GB). Weighing just 3 ounces, the i80 TravelSound speaker will easily slip into most any pocket. The iPod click wheel is completely accessible. You control volume with the TravelSound speaker, and both volume and sound quality are excellent. No batteries are required, and a convenient on/off button allows you to judiciously manage the 15 hours of playback when fully charged. You’ll also use your TravelSound speaker to recharge your iPod, so no additional wall charger is needed. At $79.99, the TravelSound is also available as part of a 4GB birdJam TravelSound Bundle.
