what you need if you need XLR outs
Just did critical listening with this in my studio last night, a huge improvement from my ~$30 RCA-out one I had before. As a studio owner, Bluetooth has always been considered a joke and not ready for primetime but this helps when people want to quickly play example mixes of differing styles from their phones. Really surprising quality even at higher volumes.

The unit works perfectly
The unit is primarily being used with a pro audio system to run Bluetooth sources thru my system.The unit is working perfectly. It is very simple to connect to my system and pairing it with a Bluetooth device is also very straightforward. The audio is excellent as well.I would also like to say that the seller’s customer service is excellent and the response to an issue that I had was VERY quickly resolved.I highly recommend this unit to anyone that needs a quality product. The unit is also very well built using metal parts especially the cover makes the unit rugged and durable. I look forward to using it for a long time.

Strong Signal
I placed this in a thick oak podium and stood back about 80-100 feet, and there was no noticeable degradation in sound. Mind you, I plan to stay within 30 feet for most uses.Our sound engineer has been pleased with the quality of the sound and the signal.

It works
I like the balanced outputs and I like that it doesn’t make an audible tone upon connection or disconnection of a Bluetooth device. After setting it up, the Bluetooth connection is automatic and long range. Sounds great.

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.
