Key Features
- 25W Hi-Fi 360° Stereo Sound with Deep Bass: Featuring dual full-range drivers, the HD77 delivers rich, balanced audio that spreads evenly in all directions. The carefully tuned frequency response ensures crisp highs, clear mids, and punchy lows without distortion—even when pushed to high volumes. Perfect for filling large outdoor areas or small indoor spaces with vibrant, room-filling sound.
- IPX7 Waterproof Rating: Certified under IPX7 standards, the HD77 can be submerged in up to 3 feet (1 meter) of fresh water for up to 30 minutes without damage. This makes it safe for use near pools, at the beach, during light rainstorms, or even if accidentally dropped into a lake or puddle. The durable mesh exterior also protects against scratches, dust, and impacts from rough handling.
- Dynamic RGB Light Show: Sync your mood with 11 customizable color modes that shift and pulse in rhythm with your music. Ideal for nighttime gatherings, parties, or simply adding ambiance indoors or outdoors. You can turn off the lights independently to extend battery life during longer listening sessions.
- TWS Pairing for True Wireless Stereo: Connect two HD77 speakers wirelessly using Bluetooth TWS (True Wireless Stereo) technology to create a true left-right stereo setup. This doubles the audio immersion, delivering wider soundstage and richer separation between instruments—perfect for larger venues or more detailed music genres like jazz or classical.
- Bluetooth 5.0 & 20-Hour Battery Life: Enjoy reliable, interference-free connectivity up to 100 feet (30 meters) away from your device thanks to Bluetooth 5.0. A single USB-C charge provides up to 20 hours of continuous playback, supporting full-day events such as festivals, road trips, camping excursions, or extended travel.
- AUX Input & Built-in Microphone: In addition to Bluetooth, the HD77 includes an auxiliary (AUX) input so you can connect legacy devices like MP3 players, older smartphones, or televisions. A built-in microphone enables hands-free calling through any connected smartphone, compatible with iPhone, Android, and other Bluetooth-enabled devices.

Benefits & Use Cases
The TREBLAB HD77 shines in environments where performance meets endurance. At the pool or beach, its IPX7 rating offers peace of mind against water exposure—no need to rush back to shore if you take a splash or drop it in shallow water. During camping, hiking, or backpacking trips, the long-lasting 20-hour battery ensures uninterrupted music from sunrise to sunset without needing frequent recharges. For home parties or backyard gatherings, the 360° sound projection fills every corner, while the pulsing RGB lights add visual flair that enhances the atmosphere. Using TWS pairing, you can double the speaker’s coverage by connecting two units side by side or across a room, creating a more expansive and immersive sound field. The AUX input future-proofs the speaker for non-Bluetooth devices, ensuring compatibility across decades of tech. Combined with Bluetooth support for modern smartphones and tablets, the HD77 adapts seamlessly to any audio source and user scenario.
Whether you’re streaming from Spotify on your phone, playing vinyl through a turntable via AUX, or taking a hands-free call while driving, the HD77 supports it all. Its rugged construction means it can handle being tossed into a daypack, carried over rocky trails, or left out in light drizzle—without compromising audio fidelity or internal components.
Important Notes
This product does not include a carrying case, charging cable beyond basic USB-C compatibility, or additional accessories. Always use a certified USB-C power adapter for optimal charging speed and safety. While the speaker is designed to resist minor drops, impacts exceeding normal handling may cause internal damage or affect performance. Ensure the charging port and speaker grille are completely dry before exposure to water. Hands-free calling clarity depends on ambient noise levels and microphone placement; performance may vary in loud environments. The RGB lighting feature consumes extra power; disabling it during long listening sessions helps maximize battery life.
