Use the Beats app to add a second Beats Pill speaker for a more immersive sound. Or play from both Beats Pill speakers as left and right output for an even more dynamic sound experience.
Note: If you’re using Beats Pill+ speakers, see the Apple Support article Use Amplify mode and Stereo mode on your Beats Pill and your Beats Pill+.
Before creating a group, make sure the first Beats Pill speaker is turned on and connected to your Android device.
Go to the Beats app 
Make sure the second Beats Pill speaker is turned on.
Press and hold the centre button 
on top of both speakers, then bring the speakers close together.
Blue lights flash on both speakers. When the second speaker is added, a tone plays and an Amplify group is created. In Amplify mode, the same audio plays from both speakers.
To create a Stereo group, tap Stereo 
Tap Amplify 
Note: If you’re playing music, playback may pause until the group is created.
Do one of the following:
Press the volume down button 
or volume up button 
on either speaker.
Use the volume buttons on your paired Android device or the on-screen volume controls in your music app.
Go to the Beats app 
The Beats Pill speaker that was playing the right channel now plays the left channel, and vice versa.
In the speaker’s device screen in the Beats app, tap Remove All 
In the Remove Speakers & Sharing alert, tap Remove.
Output returns to the first paired speaker.
You cannot use the Amplify mode and Stereo mode at the same time.
