Overview

Meet TREBLAB HD-Max, a high-output portable Bluetooth speaker designed to deliver bold, room-filling sound in both outdoor adventures and indoor spaces. Its four-driver setup combines two 75mm woofers with two 30mm tweeters to cover a wide range—from the rumble of bass to crisp highs—providing consistent audio whether you’re in a sunlit backyard or a cozy living room.

Sound that travels with you

The HD-Max is built for real life listening, offering robust 60W stereo output with deep bass that you can feel. The dual woofers handle lower frequencies while the tweeters add brightness to vocals and instruments, so playlists, podcasts, and movie moments feel immersive in any setting.

  • Rich, full-range audio from 80 Hz to 20 kHz
  • Balanced sound across different spaces, from patios to larger rooms

Rugged, ready for the outdoors

With an IPX7 rating, the HD-Max can handle splashes, rain, and brief submersion. A rugged chassis and a carrying strap distribute weight for hikes, boat trips, and campsite sessions, so you can keep the party moving wherever you roam.

Power that lasts and keeps devices moving

A 6600 mAh battery supports up to 20 hours of playback on a single charge. USB-C charging takes roughly 5 hours, and pass-through support lets you recharge a phone or tablet when outlets are scarce at the beach, on the trail, or in the park.

  • Up to 20 hours of listening
  • USB-C fast charging with pass-through power

Connectivity that fits your setup

Bluetooth 5.3 maintains a stable link up to about 33 feet, and a 3.5mm AUX input offers wired playback when you prefer a direct connection. For larger gatherings, pair two HD-Max speakers via TWS to expand stereo coverage.

Smart features and included gear

Take calls hands-free with the built-in microphone. The box includes the HD-Max speaker, USB-C cable, 3.5mm AUX cable, carrying strap, bottle opener, and user manual. This is purpose-built audio for everyday life.
