[Upgraded] 1Mii B06 Plus Bluetooth Receiver, HiFi Wi-fi Audio Adapter, Bluetooth 5.3 Receiver with 3D Encompass aptX HD aptX Adaptive for Dwelling Music Streaming Stereo System

wonderful addition to an older hifi system !
Save that old setup!I had been on the edge of thinking it was time to say goodbye to my trusty Technics receiver due to a lack of BT connection.We play a lot of records and CD’s at our house, and love the sound of our current setup so the idea of losing my existing system, and replacing it with a bluetooth friendly stereo was not the route i wanted to go. But we were really wanting to add the ability to stream audio from our phones and laptops, so something had to change.This thing was a gamechanger. I’m sure super audio nerds will find something to fuss about, but honestly, for under $50, I find no issue. Plugs right into an empty RCA input (TV in my case), and i have it piggybacked off the receiver power supply, so turn the receiver on, and it’s on. I’m sure there are “nicer” units out there that do this, but i’d be hard pressed to find one as easy on the wallet that performs as well.Been using it for a few weeks now, and no issue. Have never experienced connectivity issues, range is what it needs to me, i can be anywhere in my house, and signal never drops or crackles. Pairing new devices is simple and straightforward. Just remember to turn off bluetooth on a previously paired phone before pairing a new device, this thing locks on like a beast and as soon as it’s on, it will, if possible immediately pair itself with the last device used. Nice for ease of use, a minor annoyance in a 2 phone household where we both like to stream to the stereo sometimes.There is a “3D sound” button, but connected my my setup, which includes Klipsh 5.1 speakers, all the button seems to do is make things louder and bassier, maybe it’s more dynamic with a simple 2 speaker setup, don’t know, don’t care, its unnecessary for my use case, and has no bearing on the primary function which is what I came for.TL:DR. Great little unit, wallet friendly, small form factor, zero connectivity issues, and clear sound, big win for keeping your older hifi kicking.

Excellent and simple!
Worked flawlessly out of the box! Very simple setup (I only have one Bluetooth device). If you’re going to connect it to an RCA input on your amp, it does not come with a male to male RCA cord so you will need one. It does come with 3.5 mm to male RCA cable , the power cord and it actually comes with the power to usb device too. One last thing, this is my third Bluetooth device and the first two (not this manufacturer) had background noise and clicking sound that made them unusable. This one does not have hum or clicking and I’m pleased with it for the money (until I can afford a streaming music device). If you’re a high end audiophile, this might not be for you as it’s very simple and easy to use. I will recommend this to anyone looking for a simple Bluetooth connection to get Amazon music into an existing stereo system. I have it connected to a Yamaha A-S301 going to a set of Klipsch Heresy’s (1981 vintage) and it is working perfectly.The power cord is a little short and I had to move a few things around to avoid adding an extension cord, however that’s minor.

Does what it promised
Bought this to replace my Google casting device that was problematic. Works great. Had it connected in minutes. I was concerned about the range because it is in a closed cabinet but it stays connected to my phone throughout the house and outside patio. The sound seemed a little muted at first compared to WiFi streaming, but improved when I switched on the 3D.

This device has two features that I really like. The first is the Bluetooth 5.1 Qualcomm chip, that provides a plethora of high quality audio codecs, including the wonderful AptX HD codec. The second – and I will bashfully admit this – is the 3D Surround feature. It really opens up the sound space, and makes my aging stereo perform like it just popped out of the box.Set up was a bit tricky, as I was trying to set up the unit to work with Alexa, and Alexa can be fussy. Asking Alexa to enter pairing mode got me no where. What worked was to first pair my phone with the B06+ device, then pair the Alexa app on my phone with the device. To do this you need to scroll down to the particular Alexa device you want to pair it with, and then tap (to select) that device. That opens a pairing screen, you get the B06+ into pairing mode, it shows up on the list, you select it, and hey presto! – you’re done. But it took me about half an hour to figure that out.While it’s very, very good, this isn’t the highest quality Bluetooth Bridge out there; if you demand the finest, you’ll want to look at the B06S+, the B06HD+ or the B06pro+, as those all support the superlative Sony LDAC codec. This wasn’t important to me, as I was linking the device with Alexa, where it is expected to live out its life; and Alexa is limited by an internal Bluetooth 4.2 and SBC codec which is pretty much on the opposite end of the scale in terms of quality. It’s still surprisingly good, but paying extra for a codec that my device could never use, didn’t make a lot of sense to me. It’s also true that the B06+ supports the 3D Surround chip, whilst the other devices I mentioned do not. So for me, the lack of LDAC support was no biggie, and the 3D Surround feature was a definite plus.A quick note on quality: everyone is agreed that the SBC codec that is hard wired into Alexa is poor, and audiophiles can readily detect the difference between SBC and higher quality codecs in blind testing. To give you a benchmark of what ‘poor’ sounds like, a high quality MP3 recording is in about the same ballpark as SBC. While unsuitable for audiophiles, SBC is still surprisingly good, and considered ‘good enough’ for a device not expected to perform at audiophile levels. Like Alexa. On the other hand, those same audiophiles could NOT detect the difference between the AptX HD codec and running hard copper lines. There’s a difference, and a scope can readily show it. But the difference is so minor that even audiophiles, working with the best audio equipment, couldn’t suss out the difference. So for me, with my tin ears, the lack of LDAC is not a biggie. AptX HD is good enough.In a refreshing change of direction, 1Mii, the maker of the device, included an actual 5 Volt plug in adapter! There’s been a trend away from doing this, and even Mii does not include adapters on their battery enabled devices intended for portable use. But they did include the power brick with this device, for which I was very grateful. They earned some points by doing that.Staying on the plus side, 1 Mii also earned points by including both a 3.5mm to RCA pair cable, and a power cable to run from the power brick to the bridge. My complaint is that, while having them is nice, they’re both very short. Another 3 or 6 feet of USB power cable would have made a big difference in terms of where I plugged the device in; right now it’s plugged into the back of the receiver, in a plug that is switched. Alexa will turn the receiver off for me; but as soon as I do that the bridge will lose power, and Alexa won’t be able to power the stereo back up. Clearly I need to run a longer cable to a different plug, and I’ll do that. Had 1Mii included a 6 or 9 foot USB cable, it would have made my life easier.Bottom line? This is a superlative Bluetooth Bridge, which works connectivity miracles for a mere pittance. I enthusiastically recommend this unit, and I hope it gives you as much enjoyment as it’s giving me. Top marks!
