With iPhone / iPad

With the supplied headphones, the receiver is easy to use (the iPhone and iPad tested) - returned I have it anyway. I wanted to use my Devil headphones instead the enclosed in-ears. Unfortunately, the receiver is even at minimum volume even so loud that I could not permanently wear the headphones / wanted. (Directly connected by cable to the iPhone, the devil headphones of course is not too loud, or I would save my comment here.)

What pleasantly surprised me: The played songs from the iPhone (Musik.app or Spotify) is displayed correctly on the display of the Bluetooth receiver. And the Caller ID works and appears on the display. Next to the button Siri not can indeed activate, but you can answer and end calls, which is handy in combination with the displayed caller's name, so that the mobile phone can remain in your pocket.

If I had not been keen on my over-ear headphones to connect to it, I would have kept it safely!
