B3 Professional XLR Bluetooth v5.1 Music Receiver, LDAC & aptX HD Streamer, Built-in ESS DAC, Analog RCA, Digital Optical and COAXIAL Outputs, for Audio Mixer, DJ Speakers & PA System

I have an older Harmon Kardon main amp and a Kenwood pre amp with Jvc equalizer the system is 200 watts per channel my main speakers are infinite pro 4000’ also a set of a.r’ and a set of Bose if need be I purchased this Bluetooth adapter just because I wanted to listen to pandora not expecting the quality of sound this Bluetooth brings in my hearing isn’t what it used to be but I’ll tell you what the sound quality is amazing I hear instruments now that I never heard before this Bluetooth was installed the sound is very clean and clear and powerful the 4000’ absolutely rip and came alive with this Bluetooth adapter it is very easy to install and paired with my phone immediately with no problems I couldn’t be happier with this device one of the best purchases I’ve made in a long time do not hesitate about this purchase it’s worth every single penny believe me definitely a 5 star purchase.

Top of the line product for a fraction of the price. I emailed customer service about customizing a Bluetooth password and they sent me directions in minutes.This product has all the inputs you’d possibly need for any system. It’s a definite one and done purchase.The little things I found that made this product professional grade: it doesn’t yell “Bluetooth connected” through your speakers. Two devices can be connected at one time, but the second device needs permission to play… so that one friend can’t just rip a bad song. You can set a Bluetooth password to avoid pranksters.If you purchase directly from their site you can have them program the device exactly the way you want it to run. Passwords, the amount connected at one time, permissions…. Everything!

Bought the Blafili B3 to use as a DAC paired with powered EV speakers for my wedding. It worked flawlessly throughout the ceremony, toasts, and reception. Now I use it in my garage / workshop with the same DJ speakers I used for the wedding. The sound quality is excellent and it continues to work great. Beware that the USB-A to USB-C cord can be finicky. The unit stopped connecting via USB (bluetooth still worked fine) but a new cable solved the issue. When I reached out to the customer service email, I got quick and helpful responses from Michael -- even on the weekend. They were kind enough to ship me a new unit for troubleshooting. Really, top notch customer service. I wouldn't hesitate to buy more products from Blafili.

I purchased this for my own use. So far, so good with this Bluetooth input DAC. I had no issues paring it up and playing audio from an iPhone. The use is very simple and pretty well explained in the accompanying instruction sheet. I have only used the RCA pin jack outputs so far. It is nice to know the coaxial, optical and balanced XLR outputs are there for when I want them. This DAC could be handy for quickly adding audio inout from an iPhone to a professional mixer board via the XLR connections without needing to use transformers.I played a challenging recording of the Rite of Spring and it sounded very good. The bass definition was quite good. I didn’t take the cover off to check, but from sound quality the unit sounds like it has DC coupled outputs. The tympani on the recording sounded excellent. I also appreciate the summary information displayed on the OLED screen. Background noise is almost non existent, seemingly below detection on the preamplifier I used for testing which is about 90 dB weighted SNR.This unit is more expensive than most consumer grade Bluetooth capture devices but much less costly than units with fancy audiophile names. This seems to be a very practical balance between price and good quality sound. I recommend this unit.

I was very happy receiving this and just as happy testing this! Installation and set up was easy it has plenty of ports for different kinds of connectivity volume control is pretty cut dry and it's size and weight is good enough for being on the road with gigs. The sound quality was amazing and did not leave me feeling like it was lacking. The range was great and was good enough for my 512 capacity ballroom. Definitely buy this if you are looking for pro style and connectivity as well as reliability.

Crappy as a bluetooth receiver but an awesome DAC. USB-C to Toslink (optical) passthrough is just what i needed. I connected a Mac studio to a Cambridge Audio receiver and by using this connection I was able to control the volume from the keyboard.

Works perfectly as an extension to my older receiver. Optical output on the box is ideal. Super clean sound and silence. I love that it makes no beeps or voices. I made sure to get about 20hrs use before posting this. Hoping for extreme longevity with this.An IR remote receiver on the front would have been nice. No complaints otherwise.
