Avantree Harmony 2: Multi-Room Wireless Speaker System with 30ms Latency and Bluetooth/Wired Inputs

Seamless whole-home audio with Avantree Harmony 2

Experience synchronized sound across multiple rooms with Avantree Harmony 2. Designed for homes, classrooms, and meeting spaces, this multi-room wireless speaker system keeps audio consistent from room to room—perfect for background music, TV sound, and spoken content while you move about.

Key benefits at a glance

• Ultra-low latency under 30 milliseconds ensures the audio stays in sync across speakers, reducing claps or echoes during shared listening.
• Simple, no-app setup: connect the transmitter to your TV, laptop, or phone via optical, AUX, or Bluetooth and let the speakers auto-connect.
• Indoor-friendly performance: the system delivers even coverage in living rooms, classrooms, or offices, but isn’t designed for large outdoor spaces or very loud environments.
• Flexible source options: use either wired line-level inputs or wireless connections for versatile integration with powered mics, mixers, or other devices.

Real-life use cases

In a living room, synchronize the TV soundtrack with wall-to-wall audio, so dialogue and ambience feel natural without chasing a single speaker. In a classroom or meeting room, deliver the same announcement or presentation audio to all corners, keeping everyone on the same page. Pair it with a compact speaker setup for a small indoor event or workshop where steady, even coverage matters.

For those who value expandability, the Harmony 2 system is designed to grow with your space—you can extend coverage by adding compatible speakers and routing sources through the existing transmitter. While the maximum volume suits indoor use, you’ll still experience clear, balanced sound across connected rooms.

What’s inside and how it connects

The transmitter supports optical, AUX, and Bluetooth sources. The speakers auto-connect when powered on, with no dedicated app to manage. This combination makes setup straightforward whether you’re changing a room layout or adding another room over time.

• Optical, AUX, and Bluetooth input options
• Auto-connect on power-up for quick use
• No dedicated app required
• Expandable by adding compatible speakers

Note: The product emphasizes indoor reliability and synchronized playback, with a focus on consistent room-to-room coverage rather than outdoor-scale loudness.
