Third-party reviews

Based on ratings from across the web.
Reviews last updated: August 2026 · How we calculate this

What customers like about Audio Pro Addon C3

  • Excellent sound quality with deep, punchy bass, crisp highs, and clear mids for its size.
  • Dual connectivity with support for both stable Wi-Fi streaming and Bluetooth playback.
  • Integrated multi-room functionality allows seamless linking with other Audio Pro speakers.
  • Good battery life offering up to 15 hours of playback at half volume.
  • Convenient top-panel physical preset buttons for quick access to radio stations and playlists.
  • Premium Scandinavian design featuring a genuine leather carrying handle and aluminium controls.

What customers don't like about Audio Pro Addon C3

  • Lacks an IP water or dust resistance rating, making it risky to use near pools or in bad weather.
  • The official Audio Pro control app can be clunky, unintuitive, or difficult to configure.
  • Uses older Bluetooth 4.0 technology rather than modern, longer-range Bluetooth versions.
  • Missing a built-in USB charging port to power smartphones, unlike its predecessor (the T3).
  • Noticeably less sub-bass impact and raw power when compared directly to the larger, mains-powered C5 or C10 models.
  • Non-linear volume steps where the audio output level only seems to ramp up drastically past the 50% mark.

Verdict

The Audio Pro Addon C3 is a compact, portable wireless multiroom speaker equipped with a 25W Class D digital amplifier, two 0.75-inch textile dome tweeters, and a single 3.5-inch long-throw woofer that deliver a 60–20,000 Hz frequency range. Its standout features include dual-band multiroom Wi-Fi, Apple AirPlay, Spotify Connect, Bluetooth 4.0, a physical Ethernet port, a 3.5mm auxiliary input, and a built-in rechargeable battery providing up to 15 hours of playback at half volume. Prominent pros are its refined, award-winning sound quality, sleek Scandinavian aesthetic with a leather carrying handle, and convenient top-panel preset buttons for instant playlist access. However, its primary cons include a lack of an official IP water-resistance rating for rugged outdoor use, the absence of modern smart assistants like native Google Assistant or Alexa, and a slightly finicky proprietary app interface.
