1Mii Bluetooth 5.0 Music Receiver for Car/Home Stereo, Aux Bluetooth Adapter for Car with Volume Control Supports Hands Free Calls, 16H Battery Li...

I'd prefer to use wired headphones, but my phone started having problems with sound cutting out with cords through the lightning port. This has been great being able to use all my abandoned wired headphones. I have 4 bluetooth earbuds but I use this the most now. One reason I don't use it more is that since it's in my pocket, I can't really use it with phone calls. It wish it had a little clip so you could pin it to your shirt for when you're on the phone. Also, I've had occasions of some lag when using it on the computer to watch video, so then the picture and sound don't match up. For that reason I don't trust to use it on a zoom meeting. Also wish that I could use the controls on my wired headphones while using this, but I don't think that's even technologically possible. It's easier to say what's wrong than right, so I hope that my saying I use this everyday for hours (great battery life, even though its annoying when it is getting low on juice and other random times it plays a tone in my ear). It's a nice small size, nice pause/play button on it, plus volume controls on the side. And I think it's pretty cheap for what I get out of it. Wish I had known such a thing existed sooner; I wouldn't have shelled out the money all those bluetooth earbuds.

[Update after extensive use: Going to 5 stars now. Have now also had more experience with its microphone. For voice quality during a phone call, the built-in mic is acceptable but far from great. There have been a couple of hiccups, when it wouldn't pair with the phone. The solution was to power off the device, unplug the headset, power the device back on, reattach the headset, and pair again. It has always worked the second time around. End of update] One star less than "outstanding" for now because it's brand-new. Will increase rating if no defects encountered. I got this after getting a mobile phone without a dedicated headphone jack. I wanted to avoid using a USB-C-to-3.5mm dongle. My previous phone's charging port wore out with overuse. So the less I use the port, the better. I really didn't want to have to spend another $50$100 on Bluetooth headphones. Pairing --- Worked perfectly the first time, and quickly. After initial pairing, it seems to require only turning on the mobile phone's Bluetooth and then powering on the Bluetooth adapterpairing is immediate and without further steps. The device reports its percentage of remaining battery charge to the Bluetooth screen of the mobile device (at least when connected to a Google pixel phone). Sound quality --- My wired headphones aren't audiophile quality but are ok for my purposes. I expected inferior audio quality when using the Bluetooth adapter. But I'm pleasantly surprisedI don't notice any loss of quality during music playback. Once in a while video and audio don't quite synchronize but this eventually corrects itself. Build quality --- It's a small and probably delicate device, but it seems well madethe switches and buttons seem solid. Play/pause & Skip/Back --- I expected the play/pause button to control only music playback, but it pauses and plays both sound AND video (at least on YouTube). When I'm viewing a YouTube playlist, the Skip control immediately goes to the next video in the list, and the Back control goes to the previous video. That was unexpected. Microphone --- My headset's boom mic is disabled when the Bluetooth device is used. I didn't expect much from the adapter's built-in microphone but was surprised that I can at least use it for voice-to-text dictation. As a test, I covered the mic with my thumb. Even with the mic covered, it picked up my voice perfectly. This might not be desirable in all situations. I don't think there is a "mute" command for the mic. Charging --- Out of the box, it needed only about 20 minutes to come to full charge. I don't know yet how long it will take when the battery is depleted. Documentation --- They've done a good job with the instructions. The booklet has the usual tiny type, but the text is organized well enough and is clear. Kudos for that.
