Thanks for reaching out. Our JBL PartyBox 300 Portable Bluetooth Speaker doesn't feature Partyboost technology. You can connect compatible speakers wirelessly via TWS (True Wireless Stereo using Bluetooth connection up to 2 party speakers) or wired via one RCA output to another. You can also play music from a USB thumb drive or wirelessly stream high-quality sound from your smartphone or tablet via Bluetooth.
Sorry, there was a problem. Please try again later.
