Not only can you use it as a standard wireless headset for audio playback, the device itself has a phone speaker and mic to allow you to make and receive calls just like a mini mobile phone! This is great for being more discreet in public. I don't necessarily want dodgy people to know I am using an expensive phone in public. You can of course also use the earphones to make/receive calls.
You can also receive notifications on it from Twitter, Facebook, Gmail, SMS and Calendar. The text from these apps will scroll on the super clear screen. It will also read the text aloud if you wish. It also has an FM radio. The sound through the supplied earphones is also very impressive.
Finally you pair the device instantly with NFC, which is really convenient.
Working flawlessly on my Note 3 and callers say they can hear me perfectly when using it as a handset.
