The JBL Flip 6 speaker has several buttons and lamps across its top and side panels, and one of these the PartyBoost button. Here, we explain the function of this button, what it does, and how to use it. In summary, this control lets you join from two to over a hundred PartyBoost compatible JBL speakers together, such that they all play the same audio. Therefore, you can fill a much bigger party area with sound than you can by playing just one speaker. Further, since you may place the speakers as far apart as is typical for Bluetooth speaker distances, the possible area they can blanket large enough for most small to medium sized parties.
JBL Flip 6 PartyBoost Button Details
Use the PartyBoost button to connect two or more JBL PartyBoost compatible speakers together, in “party mode”. Thus, when synced in this way, they all play the same stream without any echoes or delays. PartyBoost mode is like Amazon’s multi room music groups found on Alexa speakers. That is, all speakers that join in play the same audio, in sync with each other.
Then, with each speaker powered on, you press the PartyBoost button on each JBL speaker you wish to add to the group.
The PartyBoost button on the JBL Flip 6 is in the shape of an infinity symbol, thus its name, as shown in the next picture, pointed at by the green arrow.

How to Use the PartyBoost Button on the JBL Flip 6 Speaker
Note that you can mix and match any combination of JBL speakers in this joined group, so long as they support the PartyBoost protocol. Most of the latest speakers from the Flip, Charge, Xtreme, and Boombox series models will work together as we describe next.
- Place all speakers within a few feet of each other.
- Power up and pair the first (master) speaker to your Bluetooth source device.
- Next, power up each additional (slave) BT speaker that you wish to join with the master.
- Press and release the PartyBoost button on the master speaker. The oval ring around the buttons on Flip 6 speakers should then light up.
- Then press and release the PartyBoost button on each slave speaker in turn. Again, this button or oval ring will illuminate on each speaker, depending on speaker model.
- Now when you play something on your Bluetooth source device, you will hear it on all linked speakers.
- Finally, you can end the connection between the speakers by pressing and releasing the PartyBoost button on the “master” speaker. You can also, without terminating the entire group, remove one or more slave speakers from it if you so desire. Do this by simply turning off the speaker you wish to take out of the group.
