- 【Auracast Speaker for Flexible Expansion】 Unlike most speakers, Harmony A1 Solo supports Auracast broadcasting to connect with multiple speakers, headphones, and public Auracast channels—ideal for shared listening across rooms or small indoor spaces.
- 【Auracast Ecosystem Ready】 Works seamlessly with Avantree’s Auracast lineup including Harmony A1, Harmony A2, Crescendo 3D, and transmitters like AudiKast 4, C82-Aura, and Voyager—making it easy to expand your listening setup anytime.
- 【3 EQ Modes & Easy Controls】 Choose Clear Voice, Bass, or Balanced mode to enhance dialogue clarity, boost low frequencies, or enjoy natural everyday listening. Simple buttons make it easy to adjust volume and switch between Bluetooth and Auracast.
- 【Great for Homes & Small Venues】 Ideal for living rooms, cafés, workshops, and other small indoor spaces. Use one speaker or pair multiple Solo units for richer stereo sound, background music, or shared listening.
- 【Usage Notes】 The speaker automatically powers off after 1 hour of inactivity. If you prefer it to stay on, simply install the firmware update from our website. Due to volume limitations, it is not recommended for outdoor use or large venues.
