  • 【Expandable Auracast Audio System】 Harmony A1 is designed as a scalable Auracast speaker system, enabling synchronized audio sharing across multiple speakers and compatible devices. Add more units to easily build a flexible multi-room audio network for shared listening.
  • 【Ideal for Indoor Shared Spaces】 Designed for indoor environments such as living rooms, restaurants, stores, rooms, and small gatherings. Due to volume limitations, it is not recommended for outdoor use or large open areas.
  • 【Up to 100M Wireless Transmission】 Enjoy stable Auracast audio transmission up to 100 meters between the transmitter and speakers (range may vary depending on environment and obstacles). Ideal for distributing synchronized audio across connected indoor spaces.
  • 【Bluetooth, Optical & AUX Input】Stream audio from your phone via Bluetooth (up to 15m– works best when your device is nearby), or connect to TVs and media players using Optical or AUX. Each speaker can also function independently as a classic Bluetooth speaker.
  • 【Usage Note】 Volume depends on both your source device and transmitter output – set them to maximum or fixed output for best results. By default, the speaker powers off after 1 hour of inactivity. To keep it on continuously, download the firmware update from our website under the “Firmware Updates” section.
