Link to the Airpulse AU-4 Bluetooth Speaker

The Airpulse AU-4 is a premium, retro-style Bluetooth speaker that I’ve been using in my home office mostly connected to my iPad Pro. The build feels high quality, the physical bass/treble knobs make dialing in the sound easy, and the extra inputs (including quarter-inch) add real versatility for a desk setup.

Pros

  • +Fantastic vintage design and premium build quality
  • +Physical bass and treble knobs for quick EQ adjustments
  • +Bluetooth 5.1 with Qualcomm aptX HD support on compatible devices
  • +Flexible inputs: 3.5mm aux and quarter-inch line input
  • +Compact size that fits easily on desks, shelves, or console tables

Cons

  • -No companion app for sound tuning
  • -Treble lacks some clarity and detail; sound leans warm
  • -No built-in battery, so it’s not portable
  • -No track skip controls (only play/pause)
  • -Ports and AC input placement can interrupt the clean look with cables
