Music Receiver
blafili B3 Bluetooth Receiver brings your music to life with advanced 32-bit audio processing and LDAC, aptX HD, aptX LL, aptX, AAC and SBC technology. The B3 lets you stream music wirelessly to any home music system, preserving every detail and nuance of your audio—even at extended ranges.
Connect hi-fi receivers, amplifiers or DACs via balanced XLR, unbalanced RCA, optical or coaxial. Two audio inputs — wireless Bluetooth and wired USB-C audio — switch seamlessly.
An ESS ES9018K2M performs 32-bit/384 kHz upsampling, extracting every detail from the source — breathing new life into even the most demanding hi-fi systems.
A 1.34″ OLED shows codec, sample rate and volume in real time. No app required, no guessing what your receiver is doing.
Rename the broadcast (up to 12 characters) and set a 4-digit pairing code per device — factory tools included, no subscription.

“it’s rare to get XLR outputs paired with high quality bluetooth codecs from a DAC at this price point”
“The sound is clean, detailed, and well-balanced across different genres of music”
“This is one of the first devices where I am happy to use bluetooth without feeling like I am compromising too much on sound quality due to the inclusion of the high-quality codecs like LDAC, AAC and aptX HD”
✓ Verified purchaseThink it’s a great value
This receiver enabled me to use my digital music library through my analog stereo and it’s really good quality. Price is reasonable also, highly recommended
✓ Verified purchaseGreat little gadget!
This thing is wonderful. I was able to play my phone music thru my very old Sony receiver and am extremely happy with it. Sound quality is terrific. I had trouble hooking it up and the company was so very helpful and had great communication trying to help me. 10/10
Finally! A Professional Bluetooth Receiver
This was clearly engineered by someone who knows what the pros actually need. The only downside is that you can't rename the bluetooth broadcast ID name.
I've been using it through studio monitors and it sounds pretty flat. SNR is huge for a bluetooth device. I'm buying another one for my personal use.
Update from blafili: current B3 firmware lets you rename the Bluetooth broadcast name and set a pairing PIN — two units in the same room can each keep their own name. You can change both in the device menu (see the FAQ under Support), or email yourfriends@blafili.com and we will walk you through it step by step.

Easy to use and sounds fantastic

Surprised with size and its performance. Attached to my monitors and they sound great for living room.
The best sounding Bluetooth receiver Period!
Typically Bluetooth audio is quite bad compared to wifi or wired streaming. Most HiFi manufacturers typically implement Bluetooth as an after thought/nice to have and focus on other areas more such as airplay, chromecast etc…. I own an audiolab 6000a play and the Bluetooth on that amp sounds like what you would normally expect Bluetooth to sound like. When I connected the B3 to the amp I was blown away at how good the Bluetooth sounded from my iPhone compared to the built in Bluetooth on the audiolab 6000a. I couldn’t believe what I was hearing. The crazy thing is the audiolab and the B3 both use the same Dac and both were streaming with AAC codec but the B3 just sounded better. If you want the best quality audio from Bluetooth look no further. The B3 is worth it over built in Bluetooth or some cheap Bluetooth addon from Amazon, Temu or Ali Express. Blafili is serious about Bluetooth. Just look at the product listings it’s all they do.
Great range, well-made
This bluetooth streamer deserves the high ratings that it has. It has great range, is well built, and has lots of connectivity options. Customer service is excellent. I had a little trouble with the install (user error) even though the directions are very clear. They were quick to respond and I was up and running in no time. I highly recommend this company and their product!
Buen audio, buena cobertura

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.
The blafili B3 outputs balanced XLR, RCA, optical and coaxial from one box — and it is an LDAC receiver on top.
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.
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.
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.
No, Multi Function Button owns these functions ONLY: ON/OFF; BT Connection Reset; Factory Reset.
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.
Yes, blafili B3 supports codecs of LDAC, aptX HD, aptX LL, aptX, AAC and SBC. blafili B3 connects with macOS Sonoma by AAC codec.
In some cases, you could get signal without the antenna but you must use it to get the best signal.
It’s convenient that all outputs( XLR, RCA, COAXIAL, OPTICAL ) are active at the same time.
No, the red light only comes on when there is music playing.
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.
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.
