Review: Genuine audiophile DAC in a powerful Bluetooth receiver/transmitter. - I’ve been working at home during the pandemic and got tired of always having earphones in so I dug an old Panasonic compact stereo out of the basement to set up on my desk. Well, the audiophile bug I’ve had off-and-on for 40 years bit again and the kit speakers soon proved unsatisfactory, so I started upgrading my system. The most important component in any audio system is the speakers, and I picked up a used, vintage pair of Monitor Audio MA 301s, which I think are probably the finest small bookshelf speaker under $1000 ever made. I was using a little Mpow BT receiver to play Spotify through my iPhone, but figured I could get much better sound quality with something that was bigger and more substantial than a device that was smaller than a pack of gum. I tend to over-research everything electronics before I commit, and was very impressed by several reviews I’ve seen of another Bluetooth DAC (digital-to-analog converter - it’s what turns digital signals into analog audio that can be played through an amplifier to speakers or headphones, and most people into high-quality music will have either a standalone DAC or a high quality one in their CD player or amp/preamp) sold here on desertcart for only 25 bucks. It’s made by a company called Mypin and got rave reviews from several audio review channels on YouTube that stated in addition to Bluetooth, it would also improve the audio quality if connected to a CD player, compared to the player’s built in DAC. So I bought the little Mypin, but also spotted this 1Mii unit that boasted an “audiophile DAC” plus also receives better-than-CD Apt-X HD signals and pretty much all other high-quality Bluetooth audio signal types. And so I figured I would give this one a try too, as I could always send it back if it wasn’t notably better than the $25 Mypin. Since we are wedded to a family Spotify plan, and Spotify won’t have lossless, cd quality audio available until some later point in 2021, I also started thinking I wanted to be able to play a lot of my old CDs to be able to have better sound quality than through the Bluetooth and decided to pick up an used Sony five disc carousel CD/DVD/SACD player to use as a transport and run its digital signal into the Bluetooth DAC unit to let the DAC convert the signal to analog (also, my amplifier has only a single pair of RCA auxiliary inputs, so I would be able to use the BT DAC as an audio switch between the Bluetooth receiver and the DAC unit processing sound from my CDs). So I needed a DAC that had a traditional digital audio input, either a coaxial one or an optical one. There are a number of audiophile Bluetooth DAC receivers on desertcart in the $100-$180 range (iFi Zen Blue, Bluedento, Audioengine B1), that have the highly regarded Burr Brown DAC chip in them but surprisingly their coaxial and optical digital connections are for output only to another DAC which makes little sense - Why equip a device with a high-quality DAC that works only for Bluetooth rather than any other digital connections? The Mypin has both coaxial and optical inputs, but the 1Mii has only one optical input; it does have a digital optical output, too, I guess if you have a higher and stand alone DAC and just want to use this unit for the Bluetooth. So my desertcart package with the two Bluetooth DAC’s arrives and I try out the cheaper one first. The Mypin did have better sound than my Mpow portable BT receiver playing Spotify and had slightly better sound than connecting the CD player directly. Then I tried the 1Mii B03Pro+..First thing to note is that unlike any of the more audiophile specific BT DAC’s or even the cheap $25 Mypin one, this unit does not have standard RCA outputs to run a pair of RCA interconnects into one’s amplifier or receiver. Instead there is only a standard 3.5 mm headphone-size output jack. Luckily, I had a 3.5 mm to RCA cable, plus there is one included in the box, but the included cable is very thin, very cheap, and has sound quality commensurate with its appearance. I replace the included one with the relatively inexpensive cable I have used to plug old cell phones into my AV receivers for several years and noted an immediate and very appreciable increase in sound quality, but with some buzzing and feedback in Bluetooth mode, unless the cable was adjusted just right in the back of the 1Mii unit. The B03Pro+ (the “Pro+” means that it has the audiofile DAC) features an ESS Sabre DAC, which I recall vaguely hearing of before, but I did some further research. I noted some audio industry news stating this DAC was being used in an LG cell phone, which initially did not have me very impressed, until I learned that model LG is generally recognized as having the finest sound quality of any cell phone. A bit further research revealed highly-regarded entry-to-mid level audiophile brands Arcam, Audioquest, Cambridge Audio and NAD use the same DAC chip in some of their standalone DAC units, as well as in amplifiers and cd players. So how does it sound? So good that I put the $25 unit back in the box and haven’t given any thought of using that but may give it to someone else. I have found a good test of a system’s sound quality is how it reproduces Mighty Sam McLain’s vocals – – a cheaper system leaves his voice a bit thin whereas a higher quality one renders his voice deep, rich, and perhaps the finest male vocalist in the blues genre. The B03Pro+ does full and proper justice to McLain’s voice. I think the area where this DAC also makes the biggest impact is with soundstage and imaging. With the signal coming straight from the CD player, sound for most recordings is mostly coming identifiably from each speaker and its range is only between the two speakers. When I connected this DAC between the CD transport and the amplifier, the speakers simply disappeared. The soundstage in some recordings expanded far outside of the speakers and certain instruments or singers were precisely positioned at a location between the speakers, sometimes much higher than the level of the speaker. Using Dire Straits’ Private Investigations, one can precisely hear and visualize just where the eerie cat is crying, where the wine glass breaks, and follow the footsteps as they walk across the entire soundstage. The Bluetooth audio is also quite good, but my source is limited, not just by Spotify’s sub-CD quality, for the present, but by my iPhone 7’s Bluetooth- I didn’t realize it at the time, but Apple doesn’t use the highest quality BT transmission- Apt-X HD, which is available for some Android phone users. I haven’t used the unit as a transmitter, for instance, plugged into a television so that one could use Bluetooth headphones to listen. However, as a receiver, it has scary long range. If I want to watch some thing on my phone when I go to bed and I have forgotten to shut the 1Mii off at night, it will play the audio through the Bluetooth DAC instead of my phone, even from across the house. And this is one of its biggest negatives: although it paired very easily with my iPhone and automatically repairs with it when switched to Bluetooth mode, it does not want to disconnect. I either have to forget the device altogether on my phone or go downstairs and shut off the unit, otherwise it will reconnect to my phone, which is mildly annoying. I got a bit annoyed with the buzzing sound that sometimes happens when the cable isn’t precisely adjusted in the 3.5 mm jack in Bluetooth mode, so I bought a better 3.5mm-to-RCA cable, an Audioquest Evergreen. I am only a limited believer in the benefits of audiophile cables and wires, and don’t think that anything above the $50 range typically would produce a notably better sound that could repeatably be detected in a blind listening test by the vast majority of people. However, I did notice a significant improvement in the sound using the Audioquest cable, not merely that the buzzing and feedback had disappeared. On the Cowboy Junkies’ beautifully recorded The Trinity Session CD one can hear subtle breaths by Margo Timmons in her soft but beautiful voice. Her brother Michael’s outstanding (and under-appreciated) guitar work is also improved with more detail. The Audioquest cable is a recommended accessory- the 3.5mm-to-RCA cable that 1Mii includes in the box does not do justice to the audiophile capabilities of this DAC. In conclusion, I am really enjoying high quality music again right on my office desk and this 1Mii Bluetooth DAC is a big part of it. I highly recommend this unit and even if one rarely would use the Bluetooth functionality, it is a very solid value at about 75 bucks just to use as a standalone DAC.
Review: Great for the Hearing Impaired - For many years, I have been hearing impaired. When listening to a TV, I have been unable to clearly understand speech even at external speaker volume levels that annoyed everyone else in the room. To watching TV by myself I was able to improve the situation by using hearing impaired Bluetooth headphones. That's all well and good but it doesn't address the group listener situation because most TVs are designed to cut the external speakers out when a Bluetooth headphone is paired to a TV. This transmitter/receiver combo totally solves that problem because the transmitter has a bypass function that enables your external speakers to work as normal while simultaneously using a Bluetooth headphone. I cannot overstate what a deal changer this is. Setup is rather straightforward once you understand the connection setup, which is not instantly an intuitive matter. I did encounter an issue with the initial unit I ordered because the digital audio output port on the unit was defective and sound was not being transferred to my external speakers. I received a replacement unit today and it works flawlessly. One typical problem for the hearing impaired with Bluetooth headphones is the latency (lag) between hearing speech and seeing the close-captioned words on a TV. This unit totally eliminates this issue with a low latency button. Another positive with this unit is that it is capable of handling multiple audio codecs including aptX adaptive. One rather unique feature of this particular Mii unit is that it comes with an advanced audiophile quality DAC (digital to audio) converter. This advantage is primarily important when listening to wired external speakers and the unit's high signal to noise ratio will render greater detail for the listener. The unit only comes with a one year warranty, which you should consider. It also has no remote control but found that to be an issue at all. Bottom line: I very highly recommend this unit.

## Questions & Answers

**Q: Can you change which of your 2 bluetooth devices you're are streaming too?**
A: Not automatically no. It’s quite mechanical. You either connect or disconnect a device. If u want to choose which headphones to connect to, you either have to do it from
The transmitter (which is not so straight forward), or you will to unpair / turn off the headphones that you dont want to use.

**Q: Will this connect to the bose s1, extending the distance? some dj gigs i need a wireless speaker set up.**
A: Two of them as a pair (one in transmit mode and the other in receive mode) have a theoretical line-of-sight transmission distance of 265 ft. So if that is greater than your present Bluetooth limits, and your Bose speakers have standard line-level input jacks, the answer to your question should probably be “yes”.

I’m presently using two across opposite ends of a home theater, and the nearly instantaneous “lip-sync” transmission of extremely high-quality stereo audio is truly impressive.

**Q: will this connect to a radio with a 3.5 mm headphone jack? . The radio in not bluetooth but I want it to transmit BT**
A: You can use AUX3.5mm to connect the radio and B03Pro+, and then use a Bluetooth headset to pair with B03Pro+ via Bluetooth.

**Q: Can this pair with Jabra Elite 75t**
A: Don't know, BUT It will not pair with 4  different bluetooth speakers I own. It will pair with windows laptop and desk top HP.  speakers I bought from Amazon (Doss Soundbox XL)  Will not pair. 1 out of 5  rate score for me. Amazon sent me a Email or I wouldn't waste my time. But fill my in box and you shall receive.  Buy the cheep one, check the Frequency of your device FIRST !!!

### ⭐⭐⭐⭐⭐ Excellent Bluetooth adapter with strong range and impressive audio quality
*by K***K on May 15, 2026*

Very impressed with the overall performance and flexibility of this Bluetooth transmitter/receiver. Setup is straightforward, and switching between different audio sources and connection types is simple once configured. The variety of inputs and outputs makes it easy to integrate into existing stereo, TV, or receiver setups. Audio quality stands out immediately, with clear, detailed sound and noticeably better performance than basic Bluetooth adapters. The connection remains stable, and when paired with compatible devices supporting low latency codecs, audio sync performs very well for TV and video use. Range is another highlight. The dual antenna design delivers excellent coverage throughout the home, maintaining a reliable connection even across rooms where other Bluetooth devices often struggle. A major advantage is the ability to connect two headphones or speakers simultaneously in transmitter mode, making shared listening much easier. It also works well as a receiver for bringing wireless audio into older stereo equipment. Overall, this performs much closer to a wired experience than expected. Music, TV audio, and streaming remain stable, and the adapter provides a clean, high-quality wireless solution with excellent versatility.
