Once again, Bose has gotten it right. The headphones use a human-friendly concept of talking you through the Bluetooth-pairing process (something I first experienced with Plantronics headsets).
Audio quality is typical Bose-fair; balanced, good mid-range, possibly a little muddy bass, but overall very pleasant for daily use. Volume levels are lower than I’d like, but probably safer. Battery life is outstanding; I’ve not gotten them below 40% even in all-day use. When the battery does die (apparently it does), you can use the included cord to still use the headphones - very smart and something I wish the QC3’s did.
They come with a carry-case (very useful) and seem quite durable. I’m not convinced on how the headphone foam squishes when in the carry case, but I suppose thats what a manufacturers warranty is for.
Get a pair - that way, you too could be as cool as this stock-image hipster.
