blafili B3 Bluetooth Music Receiver

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

Excelente producto de fácil conectividad.

Excelente producto. Ya he comprado varios para diferentes lugares. La conectividad es muy facil. Lamentablemente alguno hacia un fuerte ruido pero fue reemplazado sin problema. Todo perfecto ahora.

excellent unit for the money

I've been using this off and on for about a year now, I have it set up with a pair of fosi mono v3's and DM40's, its performed admirably with zero issues and the audio quality is excellent via LDAC.

you really can't go wrong with this unit, its nice and simple, no extra buttons dials knobs, none of that. it just WORKS.

just buy it already!

Great quality heavy duty unit

I've been using the B3 for about 6 months now. I mainly use it to pipe music through my band's PA system and its been doing a fantastic job. No pairing issues, no drop outs, good range, excellent sound quality, and it's a very robust unit. It's handled the normal 'abuse' of being regularly plugged in and unplugged and being trensported around in a gear bag with a bunch of other equipment and cables, so its had its fair share of knocks and bumps along the way.

This is a high quality product that I would recommend to anyone, particularly those of you looking for a heavy duty 'gig-ready' bluetooth solution.

Ridiculous

I love it when something just works—and this does.

My older Marantz receiver started having HDMI/HDCP issues with my PC. It still sounds great (and wasn’t cheap back in the day), but the constant screen flashing for 10 minutes at a time was getting old fast.

I picked this up to bridge audio from my PC to the Marantz using an optical cable, and it solved the problem immediately. Setup was simple. You can connect via USB (which the instructions say offers better sound quality) or just use Bluetooth. I’ve tried both and honestly can’t hear any difference in fidelity.

I’ve only had it a couple of days, but so far it’s been rock solid. If you’ve got an older receiver you still like, this is a great way to keep it in the game instead of replacing it.

7/25/2026 Update

Still works well but noticed that the sound quality with a USB connection is much better than Bluetooth. Sometimes is switched to BT by itself and you will notice the quality drop. easy enough to switch back with the front panel button though. USB only alt to consider: ASIN B0B2DBGKL3

Excelente compra
