Bluesound PULSE FLEX Wireless Streaming Speaker

Compact BluOS design with 50 W total system power, Wi-Fi 5, AirPlay 2, TIDAL Connect, Qobuz Connect, aptX HD Bluetooth, stereo pairing, and surround-speaker use with compatible Bluesound systems

The Bluesound PULSE FLEX is a compact all-in-one speaker designed to bring serious streaming capability to bedrooms, kitchens, offices, and other spaces where a full hi-fi system may not make sense. It combines BluOS multi-room streaming, built-in amplification, custom-tuned drivers, and flexible wired and wireless connectivity in a small enclosure that is easy to place on a shelf, desk, countertop, optional stand, or wall mount.

Use one PULSE FLEX on its own, pair two for true stereo listening, or use a pair as surround speakers with compatible Bluesound home-theater products. Through the BluOS Controller app, you can stream from more than 20 music services, listen to internet radio, play from your local digital library, and group Bluesound products throughout the home for synchronized multi-room playback.

Despite its compact size, the PULSE FLEX is built with a 50 W SmartDSP amplifier section driving a 0.75" tweeter and 4" woofer. It supports high-resolution playback up to 24-bit/192 kHz, along with formats including FLAC, ALAC, WAV, AIFF, MQA, and DSD256. AirPlay 2, Spotify Connect, TIDAL Connect, Qobuz Connect, Roon Ready support, and Bluetooth 5.3 with aptX HD make it easy to play music from the sources people actually use every day.

Physical connections include Gigabit Ethernet, Wi-Fi 5, a 3.5 mm optical/analog combo input, USB-A for external storage, and USB-C for computer audio. Three top-panel presets give you quick access to favorite stations, playlists, or inputs, while built-in IR learning allows integration with an IR remote.
