Impressive and speedy customer service! well built
This Bluetooth receiver sports many features that we (as professional AV installers) have been looking for. The ability to assign a specific BT name (via software that their customer support provided) is excellent . The ability to set a Pin # to only allow specific devices to pair is very helpful in the churches and schools that we work in. The XLR outputs are a very nice plus as well as the removable antenna. Great product at a fair price. Their customer support was very prompt to reply to questions. Will be back for more soon! thanks.

Best Bluestream receiver
We are AV Integrators, and this is our 'go to' product for all our installations. Over the years we have tried many Bluetooth receivers, but for pro level features and performance, this by way ahead of everyone else. Stable, long range connection, highest audio quality, ability to name and password, balanced outputs, ability to unpair an unwanted auto connection at the touch of one button, are features you just don’t get on other units. Oh, and the after sales support is unmatched, wish there were more suppliers like these guys! If you are serious about using Bluetooth, this is the receiver to go for.

Good sound quality. Easy setup.
Was a little leary to try this due to some of the bad reviews, but I'm very pleased with it. Setup and pairing couldn't have been easier and I'm pleasantly surprised at the quality of sound. Of course the quality of signal to the BT receiver, quality of connection to the stereo receiver (I used the optical connection), quality of receiver and speakers all contribute to how good it sounds. If all of that is high end you'll be very pleased with this product. If not, oh well. They say you can put lipstick on a pig but it's still a pig. You can use this with a low quality system and you'll get low quality sound.

Best Professional (and consumer) BT Receiver I've Bought (and I have bought a lot)
Finally a pro unit worth buying. XLR, RCA, and digital outs. Fantastic range and **The Ability To Program BT ID**. Setup was easy and simple but I could not figure a way to have the device pre-programmed and delivered to me. I contacted Blafili support and within minutes (!) I had clear instructions in my in-box. Naming the device took maybe ten minutes and that includes installing the software. Naming is a very desirable feature. This is not only a well-thought-out device but worthy of being called 'professional'. The only part I have not researched is maybe adding a better external antenna to increase range; this may not be desirable from Blafili standpoint but I'll give it a try and edit this post if I do it.

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.
