About the Bluesound Pulse Flex
Wireless music for the audio enthusiast
Wireless music for the audio enthusiast
If you're serious about your music and its sound quality, here's good news. With the Bluesound system, you can play your high-resolution music and enjoy the convenience of wireless multi-room audio throughout your home. Bluesound was designed by the makers of NAD electronics and PSB speakers, both experts when it comes to delivering high-performance audio.
Ultra-compact high-performance speaker
The Bluesound Pulse Flex is quite small — and quite powerful. It features a 1” tweeter and a 3-1/2” woofer, each amplified separately to ensure an accurate response. You'll enjoy clear, detailed mono sound that puts most similar-sized Bluetooth speakers to shame.
A universe of music options
Bluesound is compatible with virtually all digital music formats — including high-resolution files up to 24-bit/192kHz. Access the music stored on your computer or a networked hard drive. Stream from Internet radio stations and online services like Spotify®, Rhapsody, and TIDAL. You can also enjoy downloads from high-res music sites such as HDtracks. The player is compatible with MQA, an up-and-coming high-resolution audio format. The Pulse 2 also features a USB input for playing files "locally" from a thumb drive or hard drive — ideal when friends come over with their own music.
The Pulse Flex features aptX® audio coding, an advanced form of Bluetooth that allows higher-fidelity sound with compatible Bluetooth devices. The system is backward-compatible with earlier forms of Bluetooth, too. Bluetooth is a convenient way to play the sound from any app you might be using on your mobile device, including Netflix® and YouTube™. You can even share that Bluetooth source with other Bluesound music players around your house that are connected to the same network.
