1Mii B03Pro Bluetooth 5.3 Transmitter Receiver for Home Stereo TV, HiFi Wireless Audio Adapter with Audiophile DAC & aptX Low Latency/HD/Adaptive, Long Range, Optical RCA AUX 3.5mm Outputs/Inputs

The Wii B03Pro is a fantastic choice if you're looking for a 5.0 Blutooth receiver to stream music. In this review I'll only be speaking to the audio part in relation to a stereo receiver through the use of iTunes only. I have a recapped 1980 Pioneer SX-3800 stereo receiver connected to a set of KEF iQ1 bookshelf speakers. My Pioneer receiver does not have Blutooth which is expected regarding integrated stereo receivers from the '60's though the very early 2000's. The first thing you should know is that like all Wii products, it's lightweight (plastic) and yet, it does not feel cheap. The B06Pro has a built-in ESS Sabre DAC so you're going to get improved sound quality than cheaper blutooth receivers. The top display is easy to read and not overly present with brightness from the LED's. The display provides very basic info regarding the particular connection and nothing more. It will NOT provide song information. You'll have to spend a little more money to buy the B03Pro+ to get a active sophisticated screen display. This unit comes with a 3.5mm to RCA cable, USB Cable, a Toslink cable, and a 5 volt power supply. The setup is straight forward and you'll be up and running in a matter of minutes. You also have the option of using an external DAC if you prefer. Regarding the 3.5mm to RCA cable connection, there is a misconception, in some circles, that such a connection has inferior sound. That's not true at all. That opinion is nothing more than a misinformed audiophile bias toward traditional RCA to RCA connections. If you don't like the included 3.5mm to RCA and/or Toslink cable then you can buy a higher quality cable on Amazon to easily mitigate the issue and you'll be on your way. I have an iPad from 2021 and an iPhone 12 of which to stream from as well as my MacBook Pro all of which connect very well with iTunes. If you have an Android phone or Microsoft tablet/ laptop / or desk top PC with blutooth, you'll also be good to go as the B06Pro has all of the usual codec compatibilities. It's small and I do like that it has an on/off power button and an on-board volume control which is surprisingly not options for the iFi Zen Blue 5.0 receiver that costs roughly $120 more. The big thing to consider is the price point of $79.99 It's considerably cheaper than the above-mentioned iFi Zen Blue, Audioengine, Lavaudio, and Blu Dento 5.0 or 5.1 bluetooth receivers. The audio quality from iTunes has been excellent when used with this device. Instruments are separated and quite detailed. I have not heard any noise or experienced any interference with the signal during playback. Overall everything sounds clean, articulate and full. Keep in mind that your listening experiences may vary. We all listen differently and own different audio equipment in different sized rooms, so reviews regarding sound quality are always quite subjective. I highly recommend getting the added product protection. For roughly $8.00 at the time of this review you get 2 or 3 years of protection in case something goes wrong. Everything is an investment so by all means, get the protection plan for peace of mind. If you're on a tighter budget, in need of adding blutooth to your stereo setup, and still want to get some higher quality sound, then the Wii B06Pro should be on your short list of considerations. Thanks for reading!

This would be my fourth Bluetooth transmitter I've tried for connecting my wireless Bluetooth headsets for watching TV, and it's by far the best one. All the others had various pairing issues, limited features, lag, poor signal range, etc. This one solved all my needs. Pairing and connection--it's fast! My headsets almost instantly reconnect on power up. Other devices usually take a few seconds. Pairing is super-easy, and it identifies the correct mode to use--whether it's atpX, atpX LL, AtpX HD, etc., so you don't need to fuss with any of that. Range - fantastic! Other devices I've used usually start to break up if I walked downstairs in my house (transmitter upstairs). With this, I can not only walk downstairs, I can be on the other side of the house and even in the attached garage without any of the signal breaking up or BT disconnecting. AC powered - don't bother with those other devices that need to be recharged, if you don't need it mobile. Features - every aptX/non-aptx mode you'll need, and it can support one mode for the first headset paired, and another mode for the second, simultaneously. All auto-negotiated. One con, but not unique problem to this device - it auto-pairs to any BT audio device that's in pairing mode and in range, if you don't have two BT devices connected at the time. This can get annoying. Imagine you're watching TV, and your spouse has a BT speaker in another room that goes into auto-pair mode when it turns on--it'll suddenly blast the TV audio! The only workaround is to making sure you have two devices connected when another auto-pairing device is powered on--after that stops pairing, you can disconnect the second device. What a pain.

In a pinch for digital connections, it will do nicely. It looks nice, with a small foot print and elegant gold-colored plating on the switches. For sound quality, it's about what you would expect for any digital setup -- certainly not on par with high-end-analog, but quite serviceable. I haven't listened closely for noise yet. On range, using this unit as a receiver, the connection reaches 30 feet into another room -- line of site, no walls, some furniture. My "phone" is able to play MP3s through my high-end sound system. The downside is the laughably, comically short cable and plug lengths. While this is industry standard for cheap good like this, I cannot let them off the hook. The cable barely reaches from one end of my amplifier to the other, much less out the back and to the unit home next to the turntable. An extension solved this problem, but why should an extension be required? 6' cables would be better.

I had no idea how to connect my 40 year old stereo to a set of bluetooth speakers for the rest of the house. This is the ticket - simple as pie to connect. It has volume control on the box to control the signal you send to your remote speakers, most speakers have volume control also and the volume control on the stereo drive all of it. No delay. I can crank the volume on the stereo and the sound coming out of the Bluetooth speakers upstairs is in perfect sync. Highly recommended.

I have paired this 1Mii Bluetooth transmitter-receiver with an class A stereo amplifier setup. Absolutely superb sound quality! The 1Mii will complement any device or system. Also I can freely walk around the house without the Bluetooth dropping out. Excellent product!

I was worried about the volume control. One of my headsets doesn't have physical volume control(resistor), it can only send signals to the transmitter, soI was worried if it will reduce the volume on another pair of headsets, but it works independently. That's more than I expected from this device. Paris quickly each time I turn on two headsets and the device.

great little dac b/t transmitter reciever easy to install works perfect.

I put one of these in a basement workout area which has ceiling stereo speakers and a TV. With a flick of the directional switch we can either watch a show or listen to music from our phones over Bluetooth, as the single output runs back to the receiver (in another room) and out the speakers. Excellent product to make things very convenient to change back and forth. Highly recommended if you want to add some simplicity and versatility to your audio setup.

I bought this to use as a transmitter for my home theater, paired with a 1Mii SafeFly Dot Airplane Bluetooth 5.3 Transmitter Receiver connected to my headphones. I need aptx low latency to work for my home theater. It connects correctly to the reciever, but I can not get the low latency codec working, no matter what I do. Very dissapointed.
