I'm really impressed with the tidy product design of this Mic Mini set, by drone manufacturer DJI. It's a pair of wireless mics and a receiver all bundled in a charging case, which provides up to 48 hours of battery life. The mics themselves are handsome sculpted and weigh just 10g each. They can be clipped onto clothing or attached magnetically. They're noise-canceling, with two strength levels you can choose between. Windscreens are included. The mics can connect via Bluetooth to the company's line of action cams. Alternatively, you can plug the receiver into your DSLR's hot shoe. There's also an iPhone adapter, if that's what you're shooting with. These run $169.
