1Mii Aux to Bluetooth 5.0 Adapter 3.5mm Bluetooth Receiver for Car with OLED Display, 3.5mm Jack Kit with Volume Control Supports aptX-HD & Hands-...

I've had this for a couple months now. I have a late 2000s Toyota with a CD player and aux port. The Bluetooth works seamlessly with my phone. When I want to connect the device, I just flip it to "ON" and it quickly auto connects after pairing my phone once. The internal battery holds a charge and last a good amount of time. I've recharged it once or twice. I read that if you run the device while charging, there will be whining or interference. I tried it once, just to see what would happen. I didn't experience any undesired effects. The sound quality is as good as my stereo system allows. I use it to listen to Pandora or SiriusXM apps. Phone calls work fine, too. This device is exactly what I was looking for and I have no complaints. It does what it is supposed to do and does it well. It is small, unobtrusive, and not an eyesore. If you need a Bluetooth adapter for your older vehicle, I highly recommend this product!

It couldn't be simpler to set up. Galaxy S22 Ultra connected to it with no problems using LDAC. Sound quality? I mean it's in a car so a $1000 Dac will sound the same as a $5 dac implementation. Comes with a short charging cable which is perfect for my car (Lexus LS460) in-glovebox aux and power connections. Also comes with a longer audio cable in case you want to place the receiver somewhere else. It works perfectly inside the glovebox with the lid closed, no wires, nothing to see or worry about. Hook the power up to a cig lighter usb adapter (if you don't have a usb port in an older car like mine) and dont worry about it ever again. Overall it's the only BT adapter I found that supports LDAC codec so it's worth the $10 extra price premium. Alot of the other adapters being sold boast about their Bluetooth version numbers, like 5.1, 5.3 etc. That refers to the power usage and range. It means absolutely nothing in terms of audio. What matters is what codec it supports. AptX, AptXHD, AptX Adaptive, SBC, or LDAC. SBC is the worst of them all, which, if you're shopping for one of these, is the default lowest tier in terms of audio quality. If they don't state what codec they support, then they support only SBC. Believe me - if their receiver actually supports any of the better codecs, they WILL advertise it. Out of all of them, AptX Adaptive is the highest bitrate and quality, followed by LDAC, then AptXHD and AptX, then finally SBC. Don't be fooled by some Bluetooth version number - always look for the codec they support. If you have an iphone, then you're screwed because Apple doesn't support any of these codecs, they use their own proprietary one which none of these units support. So you'll be stuck with SBC.

After looking a long time I finally ordered the 1Mii Aux to Bluetooth 5.0 Adapter. It is doing exactly what I want it to do with only one small issue. What I want it to do - connect with my Bluetooth transmitter behind my TV using aptx-ll, it does and always works and is a no brain work required device. It does not drop sound it just does the job solid. I also wanted a unit that has volume control so I can watch TV late at night and adjust the volume as needed due to when you change channels or streaming service the sound level changes. Plus the commercials are always louder. The1Mii Aux to Bluetooth 5.0 Adapter fits the bill and even had a mute button I can find and hit while it is in my shirt pocket. The only down side for the 1Mii Aux to Bluetooth 5.0 Adapter is sound quality, it is just not up to full snuff and produces flat and at increased volume tinny sound. I have ordered 4 separate Bluetooth receiver units before I ordered this one and have gone from almost to pathetic to great sound but no volume to the 1Mii Aux to Bluetooth 5.0 Adapter. I have 2 other units I am sending back and have done back to back comparison test with these other units. One is about the same but is trouble to get connected. The other, the Lavales Bluetooth 5.2 Transmitter Receiver connection is solid like the 1Mii Aux to Bluetooth 5.0 Adapter but has no volume. But oh baby does it have rich full sound with bass that will rock you. Tested it Side by side with the 1Mii Aux to Bluetooth 5.0 Adapter. So there is no Bluetooth receiver unit that does what I want 100 percent. But the 1Mii Aux to Bluetooth 5.0 Adapter is close enough. I have other ear buds that do not have aptx but do have full rich sound that I use for music. I don't need the high fidelity while watching TV I just need the sound of some one talking to match up with their lips moving. So when the 1Mii Aux to Bluetooth 5.0 Adapter arrived I put in one wired ear bud and took the other out and turned up the TV sound and there was no perceptible difference in the sound timing from my right ear listening to TV sound from the TV speakers and this unit in my left ear. PERFECT. That is what I wanted more then anything else. Oh, one other piddly issue, this unit is so darn small I had trouble winding up my 2 ft earbud cord and using a rubber band to secure it to this unit, finally figured out a way and "boom", done, winner winner chicken dinner. If you, like me, want the 1Mii Aux to Bluetooth 5.0 Adapter to listen to TV using a transmitter that has aptx-ll and that will give you a rock solid aptx-ll connection and perfect lip sync to watch TV, look no further, buy the 1Mii Aux to Bluetooth 5.0 Adapter now, I fully 100% recommend it. ----------------- Other Bluetooth receivers tested before buying the 1Mii Aux to Bluetooth 5.0 Adapter. All these below where ordered tested and returned 1. EarFun Air S Noise Cancelling Wireless Earbuds. Problem, turned off after 10 minutes every time used. 2. Lavales Bluetooth 5.2 Transmitter Receiver. Problem no volume control but oh what beautiful rich sound. 3. HIFI WALKER H2, HiFi MP3 Player with Bluetooth, Portable Digital Music Player. Problem 4.0 Bluetooth that dropped and never connected with aptx even though it was claimed to have it. if Bluetooth connection would have been solid with no drop outs I would have kept this unit and lived with the vary slight delay in sound and lips moving as it was really cool. If they ever come out with an updated version that has 5.3 bluetooth with aptx-ll that works, I will buy another one of these. 4. YMOO Bluetooth 5.3 Transmitter Receiver. Problem, felt clunky, was not easy to get connected and connection wasn't solid, just did not like it. was hard to get the aptx connection to work. Here is the Bluetooth transmitter I have behind the TV: CARPURIDE Bluetooth 5.0 Audio Adapter ASIN B098QGXRHF. It has a LCD screen that shows the name of the Bluetooth device and the connection type, aptx-ll aptx-HD or regular connection with no aptx. aptx-ll stands for aptx low latency, this is what you want when listening to the TV using Bluetooth to get sound synced up with the person on TV's lips moving.

This little unit replaced a similar one that broke. Its sound is excellent! Bluetooth connections regularly transmit at a lower quality than the hi def files I have stored on my phone and computer so there is a noticeable, if slight, drop-off in sound fidelity compared to wired connections. This one has the highest quality sound transmission of any small Bluetooth adapter I've used. It is compact, simple to use, and very efficient both in battery and controls. The best part of this one compared to others is that it uses a dedicated on/off switch instead of a multi-button for powering on. This means I don't have to hold it down and wait for it to turn on; I don't have to guess if it's on or not or crank up the volume to hear it's tone; I don't have to wait for it to power on or connect; and it doesn't malfunction or bug based on how many different uses the button controlling the power has. It just turns on, connects and starts playing whatever I send to it right away. I can't stress enough how much better an interface that is. This adapter is great, and better than advertised.
