1Mii B06S+ LDAC Bluetooth 5.2 Receiver for Home Stereo Hi-Res Music Streaming, Hi-Fi Wireless Audio Adapter w/aptX HD Low Latency, Long Range Bluetooth Audio Receiver Volume Control, RCA/3.5mm Outputs

Great product, worked without a hitch.

Funciona bien y contempla buen volumen sin perder calidad alguna.

I got this to turn an old Bose iPhone sound dock into a Bluetooth speaker. I also plan to use it in the summer to enable Bluetooth connection to an olderstreo system I use outside. This Bluetooth receiver includes a USB power adapter and cord and a stereo cable with a 3.5 mm jack on one end and RCA phono plugs on the other. I connected the cables and it powered up in pairing mode. I followed the included instructions and easily paired it with my iPhone. As shown in my attached video, the buttons on this unit can be used to control the music playback from the connected device. It can change the volume, pause and resume playback, and skip tracks. It allows you to pair with more than one source, although of course only one can be connected at a time. I was also able to easily pair it with a CD player that transmits via Bluetooth, and the 1Mii controls worked with the CD player as well. I also paired it with an Amazon Echo smart speaker and that worked well too. The sound quality and range are both very good. This may not be the least expensive Bluetooth receiver, but it is a well-made and attractive device that just works great.

Initially worked well, very simple procedure to pair with bluetooth equipped TV, stopped working after 1 month. The device could be seen by my mobile phone and by the TV but it was not possible to connect.

I bought this to add Bluetooth to what's otherwise a retro stereo system with older components. I specifically chose this model because it supports LDAC and AAC, which means I should be able to use both my Sony Walkman DAP and my iPhone with the best codecs they can support. AptX HD was a bonus but it turns out, it's really nice to have. Most of these cheaper Bluetooth receivers only support SBC, which you can tell because they don't mention codecs at all on their product pages. SBC is the default Bluetooth audio codec, and generally considered the worst. It's similar to mp3 in that it just uses older compression technology, but everything with BT supports it as a fallback mode, so it always at least works. But, I wanted something with the better quality codecs my players will support, AAC in the iPhone's case and LDAC (and AptX HD) in my Sony player's case. Well, LDAC basically doesn't work at all. It's almost comical; it usually plays tracks at about 4X speed, so it's like listening to The Chipmunks. Very occasionally it will do this borderline disturbing thing where it will actually play at normal speed but somehow mix the 4X speed and normal pitch together. It sounds otherworldly when that happens. But there's no rhyme or reason to when this happens; it seems random. I have to believe it's got something to do with the bit rate, and my player sending a different bit rate than the receiver is expecting. But here's the thing: LDAC is a Sony codec and my player is a Sony player with LDAC. So while I wouldn't 100% put it past Sony to mess up the implementation of their own codec, I think it's way more likely that the problem is this cheap third party receiver. In any case, LDAC is just totally broken. I've tried everything I know of to fix it. And it's disappointing because as I said, this was one of the big reasons I chose this receiver. I almost sent it back immediately for that alone. My Sony player does also support AptX HD, which is the next best thing, so I tried that and it turns out this "nice to have" feature on this Bluetooth receiver is probably what I'm gonna end up using, because it does work. I've so far had no problems with it. It's probably enough to keep me from returning this device. I've also tried my iPhone, which supports AAC, with of course SBC being the fallback. Now, my iPhone connects just fine, but I don't know whether it's using AAC or SBC because this BT receiver lumps them both together and displays them with the same color indicator light. (The codec it's using is normally indicated by the light color, but both SBC and AAC are colored the same blue.) This is partly an Apple annoyance too because there's no way I know of to get the iPhone to tell you what codec it's using either. There is, to me, a very obvious sound quality difference between AptX HD on my Sony player and whatever the iPhone is connecting with. AAC shouldn't sound *that* different, so it makes me think it's probably actually falling back to SBC. But I have no real way to know; it could just be the iPhone itself. It does, again, at least work. And that's probably enough for a lot of people... but then why spend extra for a device with these extra codecs? Just get the lower, cheaper model (without the "+") that only has SBC. Overall sound quality is okay, not great. These things also have to have a digital to analog converter inside to convert the received digital audio back to analog for output, and at this price the DAC probably isn't the greatest. I've done an A/B comparison between my high quality CD rips over Bluetooth with the same track direct from CD on this same system, and the actual CD sounds clearly much better even than the AptX HD connection with my Sony player. So I think it's just the DAC. There are some much higher priced Bluetooth receivers on Amazon, and they may have better DACs, but it's really hard to know in advance because I don't think anyone really does in-depth testing of Bluetooth devices for sound quality. It's always possible that one higher priced model does have a better DAC, while another just costs more money for nothing. Final complaint, I promise: there is no on/off button. What the heck? Unless you use a power strip that you turn on and off itself every time you want to use your system, you literally just have to unplug this thing every time you want to stop using it. You could just leave it on, of course, but then you're using power because it doesn't ever seem to go into an actual standby mode on its own. It just sits there blinking, trying to pair. I'm definitely a bit disappointed. I know it's a fairly cheap receiver, but I did pay a little more for features I'm not really getting, and then certain things (like the missing power button) I just didn't think I needed to worry about because they just should always be there. I'm still about 50/50 on returning it, but the alternative is probably to just try one of the much more expensive models, but I feel like that could turn into a wild goose chase due to unmet expectations at that higher price. At least the price on this is low enough that I might be able to just overlook the various issues with it, and at least live with it long enough until I *know* of something with better sound and working LDAC. Again, it works. If that's all you care about, it will do the job. It will play your music with at least some sort of codec. It may not play all it's supposed to and it may not sound the best, but it will definitely output audio that you can hear once you connect it to an amplifier of some sort. And I know that's all that a lot of people want.
