You don't need a special "micro USB power supply". You can charge it from computers or any charger with a USB port, including Apple's iPhone/iPad chargers. If you don't want to carry two cables, you can get combo USB to Lightning/Micro USB cables for a few dollars (those come in handy because Micro USB is the established standard for charging portable devices for everything except Apple products).So, to charge them you need another different charger. How about Apple paying Bose some money to offset the cost so Bose would offer a Lightning cable/power supply instead of needing a micro USB power supply and cable?
