Wireless input for the board.

Balanced Bluetooth for mixers, powered PA and studio monitors — line level in, phantom-safe, gig-ready battery.

Wireless input for the board.

Professional rigs accept Bluetooth through a balanced line-level receiver — not a consumer dongle. A mixer channel, a powered PA or a studio monitor pair takes the XLR output of the receiver like any other line source, and the phone on the soundboard becomes the playback rig for walk-in music, backing tracks or guest playlists.

The pro-specific details matter: the output is XLR male line level (it neither needs nor supplies +48V phantom power), the DAC path is quiet enough for reference monitors, and a 16-hour battery covers the longest gig without a PSU run to the stage.

Guests want their playlists Walk-in music from a phone, without handing anyone the board or a cable across the stage.
Long runs pick up hum Unbalanced 3.5mm dongles buzz over ten-meter runs. Balanced XLR does not.
Phantom power accidents A condenser-mic channel with +48V can damage consumer sends — a line-level XLR out is the safe answer.

Three boxes, zero new cables.

Line level, not instrument level

Everything in this scene hangs on one phrase: line level into a line input. The blafili XLR’s output is a balanced male XLR at line level, so it treats the mixer channel exactly like a keyboard sub-out or a CD player would. Set the channel to line, phantom off, and gain-stage with a loud track until the channel meters sit healthily below clip. Bluetooth itself should never be the thing that clips — if it does, back the phone volume down; the encode stage is the only place distortion can enter.

Line level, not instrument level Everything in this scene hangs on one…

Where it fits in the rig

Walk-in music is the obvious job, and it is a real one: the bar phone pairs, the PA covers the room, nobody crosses the stage with a cable. The quieter jobs matter more: an installer feeding a distributed-audio rack over balanced lines without pulling a new run; a rehearsal room where the backing-track phone lives in the control booth; a studio lounge pair of monitors that take streaming without touching the console. And the reverse path exists too — the Bicast transmitter takes the mixer’s output and hands it to Bluetooth speakers or a photographer’s headphones at the back of the room, with aptX Adaptive keeping the link stable at range.

Where it fits in the rig Walk-in music is the obvious job,…

The right box for this room.

Why these. The XLR receiver is the stage pick: balanced male XLR out, 16-hour battery, USB-C while-charging. The B3 adds optical/coaxial for install racks and an OLED that shows the live codec. The Bicast transmitter is the reverse path — send the mixer output to Bluetooth speakers or in-ears anywhere in the venue.

Set up once, forget the box.

  1. Plug into a line channel. XLR into any channel or stereo input; set the mic/line switch to line.
  2. Phantom off on that channel. The output is line level — +48V is unnecessary and unkind to line inputs.
  3. Gain stage like a DI. Set channel gain with a loud track; Bluetooth should clip the channel, not the DAC.
  4. Charge between sets. USB-C keeps it alive during the gig and tops the battery for the next one.

Owners in the same seat.

High-Fidelity Bluetooth Audio with an amazing value

If your are looking for a aesthetically pleasing audio receiver with great output options and extensive Bluetooth codecs support (up to and including LDAC!), you've just found one.

Looks & build:
It features a minimalistic, modern looking metal case with a clear OLED panel that displays current 'source' information, paired with a single multi function button (used to turn the device ON/OFF, enter pairing mode or clear the paired devices list).
The case has a high quality finish and great attention to detail, it's nicely rounded with no rough edges.
On the back, you will find multiple output options, a sleek removable Bluetooth antenna, and a USB-C port.

Connectivity & range:
As a Bluetooth audio receiver, it supports multiple premium codecs, including LDAC (Up to 990 kbps) which will surely satisfy FLAC format fans!
With its external antenna, it provides an excellent range.
However, keep in mind that the highest quality codec - LDAC - will start to degrade if too many obstacles are in the way.
For me, a straight line distance of about 10m through two walls started to cause signal stuttering, but it was just a practical test to see how much of a beating it could take.
In normal everyday use, I tested it at distances up to 15m when streaming from my Android phone (FLAC files over LDAC), it worked perfectly.

Output options are excellent, and it's important to note that all output options are ACTIVE simultaneously if you ever feel the need to connect more than one pair of speakers.
Unlike some competitors on the market, there is no 'volume loss' compared to a direct wired connection.

Sound quality:
The manufacturer decided to use the ES9018K2M DAC chip, which offers an analytical, bright and highly detailed sound profile.

Of course, when tested on $600 pair of speakers it sounds noticeably different than on a $150 system.
I tested it using one of my favorites, "Green Grass & High Tides" by Outlaws. It sounded great on both setups, the integrated DAC managed to pump out the details - especially during the guitar solos, delivering a high fidelity experience that made even the $150 system punch above its weight!
Overall, blafili managed to deliver a great sounding device, that enriches the listening experience and allows even the lower-end speakers to shine (up to their physical limits).

What's in the Box & Manual:
Inside, you get the main device and the Bluetooth antenna.
Additionally they included both an optical cable and a USB cable.
The user manual is clear and concise.

PIN secured pairing & Power User configuration:
The device allows you to set a required PIN code for Bluetooth pairing and lets you customize the displayed Bluetooth device name.
There is also an advanced configuration application available for Windows systems. It allows you to change the pairing PIN and tweak a myriad of other advanced options if you are brave enough to dive into the settings!

Final verdict:
Bang for your buck!

*I couldn't purchase it directly from Amazon Europe, but fortunately Blafili ships to Poland :)*

Good all around.

Needs:

I needed a long range bluetooth receiver to hook into a PA system that the name could be customized and add a pin code. This fit the bill. As of writing this review the first one has been in continuous use for 3 months with no issues.

Installation:

This is straight forward. It is a USB-C for power cord but you will need your own power brick. This was not an issue for me since the surge protector has USB power slots. Of the four output options I used the RCA to a small mixer board.

Sound and Range:

The sound is good and clear with no issues. I mounted this in a outdoor metal box since This is for an outdoor booth for music and announcements. The end user has had no issues connecting and staying connected. The second unit I bought I wanted to test distance. I connected to the bluetooth and took a walk. Through walls I was able to walk 90' away and stay connected. I did not have my shoes on or I would have went further. However 90' would be more than sufficient for the distance I needed.

Support:

I emailed support for the instructions to change the bluetooth ID. They are very responsive and sent me links to all the necessary tools with clear instructions on how to modify the name and to add a pin to the receiver. Support for me can be a make or break deal and the support I received was very responsive and helpful.

Value:

The cost is well worth it to offer customers a connection customized to them with the ability to add a pin. It makes it easy for the end user to identify what they are connecting to and the pin keeps random people from playing inappropriate music on the system.

Conclusion:

This will, hands down, be my go to for future installs.

New life for vintage stereo systems!

Great product to breathe new life into a vintage stereo system. I have a 25 year old Sony STR-D1011S. I decided to use the DAT input for the B3 Bluetooth receiver. The blafili B3 is an OUTSTANDING product that has flawless sound and coverage through by entire house. I have it paired with my Google Pixel 10 Pro and used it with several music apps such as Spotify, Kodi, and a local content player. Then came the torture test that my other portable Bluetooth speakers fail... I put some food in the microwave oven to heat it. That would normally cause noise for my portable speakers but much to my surprise the blafili B3 and Pixel 10 Pro connection was totally unaffected by any microwave oven leakage noise!

Their tech support is also wonderful if you need it. I used their support team for help with additional customizations that I wanted and they were very responsive.

This is a versatile product that is easy to setup.

Performance and range is outstanding.

Excellent value for your money

Asked in this room.

How do I connect a phone to a mixer wirelessly?

A Bluetooth receiver with balanced XLR output, such as the blafili XLR, plugs into any mixer line channel — pair the phone and it behaves exactly like a wired playback device.

Does the blafili XLR work with phantom power?

It neither needs nor supplies +48V. Its XLR output is male, line level — engage phantom only on channels that truly carry condenser microphones.

Is Bluetooth latency usable live?

For walk-in and background playback, yes. For in-ear monitoring or time-critical cueing, stay wired — that is honest engineering, not a limitation we hide.
