Frequently asked questions
How many people is the Boomster 4 suitable for?
The Boomster 4 is suitable for smaller groups up to 30 people in indoor settings. For larger events outdoor, we recommend our JBL EON 715 pro PA speaker.
How long does the battery last?
Up to 23 hours at moderate volume — more than enough for full-day events and outdoor use without a power outlet.
Can I play music from my phone?
Yes — pair via Bluetooth and stream directly. You can also listen to DAB+ or FM radio.
Is the speaker outdoor-ready?
Yes. The Boomster 4 is IPX5 splashproof — suitable for gardens, terraces, and light rain. Not for underwater use.
Can I connect a microphone?
No, the Boomster 4 does not have a microphone input. If you need a mic for speeches or music + mic, rent our JBL EON 715 instead.
How does the deposit work?
Before use, a deposit and ID copy are required — exact details (amount, payment method, process) come with the booking confirmation. The deposit is refunded on undamaged return.
