B1 Bluetooth 5.1 Hi-Fi Audio Receiver with aptX Low Latency, TI DAC, Long-Range, Analog RCA, Digital Optical (Toslink) & Coaxial Outputs

Phenomenal audio quality. I’ve used other dongles in my car in the past, and the quality is always subpar. Not only does this pair right up soon as the car turns on, every note and baseline is flawless. It’s plugged right into my aftermarket head unit RCAs, included, and makes the system so much better. 10/10.

We tested this with a vintage NAD receiver and a Teac amp (RCA in) ) both paired with excellent speakers. Sounds really good, and no connectivity issues whatsoever with iPhone 16e, 16, older iPad, or a Galaxy S25 ultra. Cant comment on range but whoever complained about distortion needs to get out the CRC and spray their pots, it’s definitely not this unit. BTW that’s a pretty broad range of Bluetooth versions. The 16e is BT 5.8, iPhone 16 BT 5.3, S25 BT 5.4, and older iPad is BT 4.2. (FYI the latest iPhone 17 is now at BT 6).

Arrived today and I had it hooked up and BTing in 5 minutes, counting the minutes spent accessing the back of my amp (lots of moving stuff). The power cord was wa-y-y-y too short to reach an outlet, but I lucked out because the amp turned out to have a USB power-out socket. Who knew? Used the optical cable. Pairing was instant, like the 5-year-old Harman-Kardon BTA-10 BT receiver on my stereo receiver (50+ years old!) -- the HK is still working perfectly, still pairs instantly. If this BluDento performs equally, I'll consider it money well-spent. At some point I'll try a listening test between the two devices, but I seriously doubt I'll be able to hear anything significant enough to worry about. I wonder if there would be any sound quality difference between optical and RCA...again, probably not enough to worry about. I promise to update if I run into any problems -- BT can be quirky, like in my Bose earbuds when the BT just failed completely (and Bose replaced them) -- or if 5 years down the road it's still working well.

This product work really well for the price. Audio sounds good and I have no issues connecting to it. However every 20-30 minutes I hear a popping sound. Not sure what would cause it but other than that it works great.

Plug and play, and used latest Bluetooth protocols. AptX HD is streaming above 500 bps from my phone from a MP3 stream. Higher fidelity may stream faster. Has its own DAC from Texas Instruments, which is certainly respectable. So you only need to plug in the RCA cables. Also has optical and coaxial outputs for your receiver or outboard DAC. Good range, connects quickly and uses little power.

Amazing product and Amazing price definitely worth every penny! Sound is clear with no interference! Installed in my truck

I decided to add Bluetooth capability to an older circa 2010 Denon AVR 2311Ci receiver to unlock music on my ipad and iphone devices. The AVR receiver has a wired USB port for ipad/iphone connectivity on the front but this is cumbersome for a two zone system. I'm using Zone2 and the pre-out connected into another separate amplifier to power two remote stereo speakers. In looking around at the various options from low-end to more expensive, I decided to go with this unit as it had two digital outputs (TOSLINK optical and SPDIF coax )which I could assign to a digital input on the AVR using its internal DAC. One of the interesting features was the TI/Burr-Brown DAC for use with the L/R RCA analog output. The spec'ed output level of the analog signals seemed good. I wasn't too worried about volume differences since my Zone 2 has it's own volume setting which I could leave cranked up as necessary, without being jolted when switching back to Zone 1 for normal A/V operation. I also have the option of boosting input levels via the receiver settings. I hooked the unit up using the L/R RCA with the supplied cables and I consider the sound to be quite for a $40 unit. The internal DAC in the unit is likely better than one in the AVR input. Bluetooth reception is good. The Bluetooth receiver is in the basement in a recessed(in foundation/concrete) entertainment and control of the unit via my iPhone is usable out to 30+ft. Bluetooth pairing is excellent-no issues. I would recommend.

The good: sound quality is fine, it's compact and I had no trouble setting it up and using it. The not so good: build quality is poor. It takes quite a bit of force to plug in the provided micro USB cable, possibly because the socket isn't lined up well with the housing. There is something loose rattling inside the device. There is no pairing button or power button. It automatically enters pairing mode whenever there is nothing connected. So anybody walking by outside could connect to it, any time of day or night, unless I unplug the sticky micro USB cable whenever I'm not using it.
