The new PartyBoost does not support the previous Connect and Connect+ features. For example: You will not be able to successfully connect the new PartyBoost enabled Flip 5 with a Connect+ enabled speaker like the Pulse 3 or Flip 4. You will not be able to connect the Boombox 2 to the original Boombox speaker.

4. Open the JBL Portable app.
5. Allow the app to detect the single speaker playing music.
6. Once detected, press the Connect/Partyboost button on both speakers.

7. Allow the app to identify both speakers.
8. Click the Partyboost button, you will see the option for Party or Stereo, select Stereo.

Please note: Stereo Mode can only be enabled when 2 of the same speaker model are used.
For example, you will not be able to achieve Stereo Mode with a Flip 5 and Flip 6, only Party Mode.
Also, it is not possible to pair speaker models with Connect and Connect+ together, or pair to speaker models with Partyboost.

It is always recommended to use our range of Soundbars, such as the JBL Bar series - if you want a speaker for your Television or Smart TV as they are designed specifically for this use, whereas our Portable speakers are designed primarily for use with Phones and Tablets.

Portable speakers with an Aux-in port, such as the Xtreme 3 and Boombox 3 - if connected through an Aux cable, should have less issues compared to using Bluetooth, however there can be issues with audio/video synchronization if used for this purpose.

Support for Bluetooth connectivity between a TV and speaker depends on a number of different factors such as Bluetooth & A2DP versions and Audio Codecs used by each device. This can vary based on the brand, model and age of the devices, however we cannot confirm if any specific combination of TV and speaker will work without issues such as latency or lip sync delay.
