Good and less-than-desirable specs fuse together in the OontZ BudZ 2, which is IPX5 water-resistant and features Iso-fit ear cushions to cancel noise and improve the snugness of the Bluetooth headset -- although it comes with only seven hours of working time for a longer-than-usual 3-hour charging time.

Also called Cambridge OontZ BudZ 2.
