Can I connect the JBL Boombox 4 to a TV or laptop?
For sure! The easiest way is to connect wirelessly via Bluetooth to your TV or laptop. But for true audiophiles, the JBL Boombox 4 also supports lossless audio playback via its USB-C port. Plug it directly into your device to get the most detailed, high-fidelity sound possible, perfect for upgrading movie night or a serious music session. Requires compatible lossless audio content from supported apps or services.
Is the JBL Boombox 4 compatible with earlier Boombox models?
No, the JBL Boombox 4 is not compatible with earlier Boombox models, as it uses next-generation Auracast™ technology to connect with other enabled speakers, whereas older models like the Boombox 3 or 2 use PartyBoost for pairing.
