New item in unopened box, acquired through an Apple promotion. It's a Bluetooth wireless device that should work with any Bluetooth sound source, including, but not limited to, Apple iPhone, iPad, and iPod. Here's the official description of this item:
Unplug your Beats Solo2 Wireless On-Ear headphones and pair with your Apple iPhone, iPad or iPod and move freely for up to 30 feet of wireless listening. Take hands-free calls with the built-in microphone. Use the on-ear controls to adjust your listening experience without reaching for your iPhone. Stay unplugged all day thanks to the 12-hour rechargeable battery. The illuminated LED fuel gauge on the headphone lets you know when it's time to recharge.
