Excellent Bluetooth stereo Receiver with programmable pass code
We utilize the Blafili B3 in a school gym environment which requires a programmable passcode and excellent sound quality. Staff easily connect to the passcode protected Bluetooth unit. The antenna amplification is spot on using a 30ft extension cable and aftermarket Yagi mounted on the wall. Range is excellent. Sound quality is excellent (we use XLR but also includes optical audio). No complaints and highly recommended the product.

Blafili B3 Incredible Performance
I just received the Blafili B3. I hooked it to a vintage Sansui AU-717. The sound of the Blafili is incredible. Very high quality, dynamic, excellent stereo imaging. Tested with Qo-buz source. Value to money product, highly recommended
Works Great
Very happy with my blafili B3. The sound quality is superb and bluetooth range is exceptional. We installed in a gymnasium and have no connection issues anywhere in the facility. The team at blafili was very helpful assisting me to find a device that had long range and a security PIN. I even got a custom broadcast name. Very happy with my purchase.
Excellent Bluetooth receiver!
Nothing else comes close to this unit
The Blafili B3 Bluetooth receiver has to be the best on the market. As AV integrators, we want the option of being able to restrict who can take over the playback system. Also having the additional XLR balanced outputs is great to prevent hum and noise getting into the system. The range and sound quality are second to none. Highly recommend. Nothing else comes close to this unit.

Impressive!
I was really impressed with the sound quality, far better than the built in Bluetooth in my SMSL AO200.
XLR is a rare and HUGE bonus.
Impressive Sound Quality and Versatile Connectivity - A Review of the Blafili B3 DAC
Introduction:
The Blafili B3 DAC is a versatile and compact audio device that promises high-quality sound and a range of connectivity options. In this review, we'll explore its design, setup process, audio performance, and more.Product Overview:
The B3 DAC arrives in a well-packaged cardboard box, including all necessary cables (RCA, USB, SPDIF Coax, and Optical). Its brushed Aluminium build exudes quality and robustness (It weighs just enough to prevent it from being knocked around by rigid connectors), making it a reliable addition to your audio setup.Connectivity and Setup:
Setting up the B3 DAC is straightforward. It's powered through a USB C connection but Blafili recommends using a proper USB charger when using Bluetooth Audio for optimal performance.Connectivity and Inputs:
The B3 DAC boasts a rich selection of input and output options, including USB C, Bluetooth as inputs and RCA, XLR, SPDIF as outputs. The Bluetooth connection stood out for its reliability, offering a rock-steady connection throughout our testing.Sound Quality:
The B3 DAC excels in delivering detailed audio with excellent stereo imaging. Its midrange performance is particularly pleasing, making vocals come to life. The bass response is evenly distributed, avoiding any overemphasis or boominess. The only bit of improvement I could say is in the top-end, where it can do better to bring out sparkle to match with the rest of the response in the frequency spectrum, but it's not something you would expect at this price point from a DAC.
Pros:
Versatile connectivity options.
Solid build quality.
Reliable Bluetooth connectivity.
Detailed midrange performance.
Balanced bass distribution.Cons:
Nothing at this price point.Conclusion:
The Blafili B3 DAC impresses with its audio quality and connectivity options. The company's progression from earlier Bluetooth receiver products to the B3 DAC showcases their commitment to improving sound fidelity and versatility. At its current price point there is nothing to complaint about the B3 unit other than to say that it offers a great audio experience and is recommended for those seeking high-quality sound with multiple connectivity options.

Before you ask.
Is a Bluetooth receiver with DAC worth it?
Yes when your source streams hi-res codecs: the B3 decodes LDAC/aptX HD through an ESS ES9018K2M DAC (32-bit/384 kHz) instead of leaving the last conversion to your amp, so nothing is lost between phone and speaker.
Which Bluetooth receiver has both XLR and RCA out?
The blafili B3 outputs balanced XLR, RCA, optical and coaxial from one box — and it is an LDAC receiver on top.
Does the B3 remember settings?
Yes — codec, volume and pairing data are stored on the unit; it reconnects to the last device automatically and the OLED confirms the live codec and sample rate.
Can't get anything to pair with blafili B3 ?
blafili B3 is a Bluetooth receiver not a Bluetooth transmitter, so it can't pair and connect with Bluetooth headset, Bluetooth speaker, Bluetooth receiver and other Bluetooth receiver devices.
Difficult to sync blafili B3 with TV ?
You will need to turn off Bluetooth on other devices first, as blafili B3 can be connected by ONLY one device at the same time.
Do you have to push a button to pair device ?
No, Multi Function Button owns these functions ONLY: ON/OFF; BT Connection Reset; Factory Reset.
Will a Alto Professional Bluetooth Ultimate connect to blafili B3 ?
No, both Alto Bluetooth Ultimate and blafili B3 are BT receivers. What you need is a BT transmitter to pair/connect with Alto Bluetooth Ultimate. Hope it helps.
Will macOS Sonoma use AAC codec with blafili B3 Bluetooth receiver ? I've tried other devices that support AAC but macOS connects using SBC.
Yes, blafili B3 supports codecs of LDAC, aptX HD, aptX LL, aptX, AAC and SBC. blafili B3 connects with macOS Sonoma by AAC codec.
Do you need a Bluetooth antenna for blafili B3 ?
In some cases, you could get signal without the antenna but you must use it to get the best signal.
Can I use multiple outputs at the same time on the blafili B3?
It’s convenient that all outputs( XLR, RCA, COAXIAL, OPTICAL ) are active at the same time.
Digital optical / TOSLINK output red light does not work ?
No, the red light only comes on when there is music playing.
Can't get Bluetooth to work with two devices. One works but I can't get the second device to play.
How to connect blafili B3 with two phones: 1. Power on blafili B3 Bluetooth receiver 2. Enable Bluetooth on the 1st phone, search and connect to “blafili B3” 3. After pairing successfully, disable Bluetooth on the 1st phone. blafili B3 will enter pairing mode again. 4. Connect blafili B3 to the 2nd phone by the same way. 5. After pairing successfully, enable Bluetooth on the 1st phone, click to connect “blafili B3” again. 6. Now both 2 phones are connected to blafili B3. Note: Only 1 phone can play at a time, you have to pause the other.
What if my BT source doesn't support aptX? Can I still use blafili B3 and if so, how will it sound ?
You can absolutely still use the blafili B3, and it will sound great. LDAC, aptX HD are high quality Bluetooth audio codecs that work really well. With that said, in addition to mandatory support for SBC, Bluetooth also includes optional support for many other codecs, like MPEG-1, MPEG-2, MPEG-4, and AAC, all of which have their own advantages, and some of which sound very close to aptX HD and LDAC.
