Double up two Ultimate Ears devices to your Mac (or PC)

Posted by jpluimers on 2015/12/16

Two great Ultimate Ears tricks. First pairing them (thanks daleph, see also the video below):

To pair 2 devices without an app:

  1. Pair the FIRST speaker with your mac:
    1. Go to System Preferences > Bluetooth
    2. Press and hold the Bluetooth button until a tone is heard, it should appear as UM BOOM, pair it.
  2. Start playing music
  3. On the device now playing music press and hold the + and the Bluetooth keys until a tone is heard
  4. On the SECOND speaker press the Bluetooth button twice quickly
  5. After a few seconds both speakers will join together

They are only added as an identical pair, NOT Left and Right stereo

Then doing double up in stereo (thanks tomborai and McAllan):

There IS a way… you just gotta find a buddy who has the UE Boom App on either iOS or Android.

Set up STEREO mode and enable “Double Up Lock” just once with the App, ensure it plays proper stereo, then disconnect and power off both speakers.

App no longer needed.

Whenever you desire, power on both speakers around the same time, they will pair within seconds.

Then take your MAC, pair the first speaker only (LEFT), et voila, the speakers have memorized the stereo mode, enjoy!
