Bluesound PULSE FLEX 2i Portable Wireless Speaker

Bluesound PULSE FLEX 2i

The Bluesound PULSE FLEX 2i is a compact, high-performance wireless speaker built for real hi-fi streaming in any room (and beyond). It combines a bi-amplified digital power stage with custom-tuned drivers to deliver rich, size-defying sound, deep bass detail, and clean clarity at everyday listening levels. Set it up in minutes on your Wi-Fi network with the BluOS Controller app, then pull music from popular streaming services, internet radio, network shares, or Bluetooth—while enjoying support for high-resolution audio up to 192 kHz and 24-bit depth.

Use one PULSE FLEX 2i as an ultra-flexible single-room speaker, pair two for proper stereo separation, or add a pair as dedicated rear channels with compatible Bluesound home theater setups for an immersive surround experience. With aptX HD Bluetooth, AirPlay 2, and voice assistant integrations (via skills/support), it fits naturally into modern, multi-device households—while staying small enough to tuck onto shelves, desks, counters, or mounts. Add the optional rechargeable battery pack when you want true grab-and-go portability without giving up great sound.
