TREBLAB HD77 30W portable speaker

The TREBLAB HD77 is a battery-powered Bluetooth 5.0 speaker rated at 30 watts with stereo drivers and an IPX7 waterproof enclosure. It delivers 360-degree sound with a frequency response of 27Hz to 120kHz and includes dynamic RGB lighting that pulses to the beat. The package contains a carrying strap, carabiner, 3.5 mm AUX cable and USB-C charging cable for immediate indoor or outdoor use.

Suited for outdoor listeners needing rugged

This speaker suits users who want a compact, waterproof unit for poolside, beach or camping trips where submersion up to one metre for 30 minutes is possible. The 20-hour battery life supports all-day playback without mains power. Buyers who require a built-in microphone for phone calls or a power-bank function to charge other devices should look at alternatives that explicitly list those features.

IPX7 waterproof rating defines the use case

The IPX7 certification is the single specification that determines whether this model fits the intended environment, guaranteeing survival in accidental immersion up to one metre deep for half an hour. Without this rating the speaker would not be suitable for the wet, rugged conditions it is designed for.

Questions about this item

What cable do I need if I want to connect the HD77 to a device without Bluetooth?

The box includes a 3.5 mm AUX cable for wired playback from phones, laptops or MP3 players that lack Bluetooth 5.0.

Can I keep using my existing HD77 and add a second one for stereo?

Yes, the speaker supports TWS pairing so two HD77 units link wirelessly as left and right channels.

How can I confirm the HD77 is charging correctly after I plug it in?

Connect the supplied USB/Type-C cable; the indicator light shows charging status and turns off when the battery reaches full capacity.
