I too bought my first pair of wireless earbuds (One Plus) last year. I'm really amazed how well these things work. Fantastic battery life, for such a tiny package. Pretty decent noise reduction. And they always seem to guess right which of the many devices they're paired with I want them to stream from.

I was, however, disappointed to discover that when in duplex mode, sound quality drops from hifi to first generation gsm quality. As I understand it, Bluetooth still has no better profile for duplex.
