About the Bluesound PULSE FLEX 2i
Ultra-compact high-performance speaker
Ultra-compact high-performance speaker
A sealed enclosure lets you use the PULSE FLEX 2i in a kitchen or bathroom.
The Bluesound PULSE FLEX 2i is more than a compact wireless speaker. It's a high-performance wireless speaker that can be part of a Bluesound multi-room audio system. When it's linked to your home Wi-Fi network, it can stream high-resolution music with amazing accuracy. And built-in Bluetooth means you can play music from your phone and other sources, even when you're not on Wi-Fi.
The PULSE FLEX 2i has a moisture-resistant sealed enclosure, so you can use it in a bathroom or kitchen. Or combine two with a PULSE SOUNDBAR+ and PULSE SUB+ to create an incredible wireless 5.1 home theater audio system.
Compatible with AirPlay 2*
Built-in Apple AirPlay 2 technology lets you stream audio directly from your iPhone®, iPad®, or Mac® computer through your Bluesound system. That includes soundtracks from YouTube® videos and Netflix movies.
And if you subscribe to Apple Music®, you can do even more. Use Siri on your iPhone, iPad, or Apple TV 4K to control Apple Music with voice commands. Tell it what selection or playlist to play — and which Bluesound speakers or components you want it to play through.
*Firmware update required.
High-quality Bluetooth streaming
The PULSE FLEX 2i features aptX® HD Bluetooth streaming for higher-fidelity sound with compatible Bluetooth devices. The system is backward-compatible with earlier forms of Bluetooth, too. You can even share that Bluetooth source with other Bluesound music players around your house that are connected to your network.
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®, Deezer, and TIDAL (including their high-res MQA service tier). You can also enjoy downloads from high-res music sites such as HDtracks.
A USB input conveniently lets you play files "locally" from a flash drive or hard drive — ideal when friends come over with their own music.

Applications: The Bluesound Pulse Flex 2i is a versatile, full-range compact speaker that can be used in a variety of applications - including a single speaker setup, multiroom audio setup, 2ch stereo setup, or home theater setup. It can even be paired with Bluesound wireless powered subwoofer.

BluOS Wireless High-Resolution Multiroom Audio: The Bluesound Pulse Flex 2i wireless speaker is part of the BluOS wireless high-resolution multiroom audio eco-system - consisting of powered speakers, soundbar speakers, amplifiers, players, and hard-drives. The BluOS wireless high-resolution multiroom audio ecosystem uses your home's wired or wireless network to connect multiple Bluesound products and play your music in perfect sync, or different music simultaneously, anywhere in your home. Using advanced technologies (like dual-band WiFi and an ARM Cortex9 1GHz Processor), BluOS can wirelessly transmit lossless music up to 24-bit/192kHz at ultra-fast speeds with no lag and zero loss in sound quality.
- Compatible Multiroom Audio Sources: The following audio sources can be used for multiroom audio playback - internet radio (including TuneIn & iHeart Radio); online music services (including Tidal, Spotify, Amazon, Deezer, Slacker, and Napster); Bluetooth & USB audio, music libraries (computers and NAS drives); and Aux inputs (analog or digital).
- Number of BluOS Zones: Up to 16 Bluesound devices can be connected in a strictly wireless environment. Demonstrated practice has shown that you can create up to 8 groups of 8 Bluesound devices or 4 groups of 16 Bluesound devices. If you want to connect more than 16 Bluesound devices, you will need to connect the Bluesound devices to your network using a wired connection. BluOS can then control up to 64 devices in a strictly wired environment.
Note: Gen 2i of Bluesound is compatible with earlier generations of Bluesound products.
Wired or Wireless Network Connection: The Bluesound Pulse Flex 2i can be connected to your home network and Internet provider via a hardwired Gigabit Ethernet RJ-45 jack connector or wireless 2.4/5GHz dual-band WiFi 802.11 b/g/n/ac connection. The 5GHz WiFi band offers a faster and more reliable connection with less interruptions and dropouts. Either network/internet connection allows you to stream music libraries from your Windows or Mac computer and NAS drive (such as the Bluesound Vault 2i, sold separately); as well as stream select online music services and internet radio.
- Wired Ethernet Setup: A wired connection to the network is simple and requires no setup. If you wish to use the wired connection, simply connect the Pulse Flex 2i directly to your router or home network using an Ethernet cable (sold separately).
- Wireless WiFi Setup: A wireless connection allows you to place your BluOS Player virtually anywhere inside your home, but does require setup through the BluOS app on your Apple iOS or Android device.

The Bluesound system also supports compressed music files such as MP3, AAC, WMA and OGG.

Bluesound also offers gapless playback by default for all supported file music types.

MQA (Master Quality Authenticated): Bluesound is the first wireless multiroom audio system to support MQA (Master Quality Authenticated).

Headphone Output: A 3.5mm headphone jack is located on the rear of the Pulse Flex 2i for private listening with a set of headphones. The dedicated headphone driver is rated 0.0055% THD @1kHz, 35mW.
