JOINUS Mini Bluetooth Receiver - Wireless Audio Streaming for Music & More

Tom F: I found this to be a poor product. Battery very weak. It would not work to deliver sound via bluetooth if I were recharging it at the same time. And now after two years, it is totally dead. Need to buy something new, I will not buy this one again

Mz50Mz50: I loved having a wireless connection for my phone in my car! It was perfect for mine. The volume was decent since I tend to like mine louder. The battery life is good as well if you are going in your car here and there. But for long road trips you'll need to charge. It'll hold a charge from 100 for about maybe 4 4.5 hrs I would say. I did recently notice a couple months after having it that when I took it out to charge it the aux part (silver piece in my pic) detached but I just put it back and it will stay in they but this was good for the price.

Zero: I've been using this for about a year now, I wanted to wait on the review, as I have jumped the gun on these before and it turns out to be a failure a few months in. I use these with in my Crossfades and OneOdio non bluetooth both with over 50mm drivers in them. This little thing gives me a solid 7 hours or so of listing time before needing a charging. It pairs nicely with my PC using BT 4.1 and my Tablets on 5.0. The only complaint I have and why this doesn't get the 5 stars is due to adapter size, when I ordered it the fitting was not suppose to be an issue, but with both headphones it is in the way. In the pictures the it's about a 1/2 shorter, this isn't a deal breaker but when using these on your headphones to clean , all of that moving your shoulder will bump this and or get caught on things.

As for using it in my old JL audio stereo for my record player it's amazing! This lets me use 5.1 channel bluetooth speakers with this setup and really get the quality out of my old records and new ones. I must say after a year I wasn't expecting the battery life to hold up so well as it has. Good on them! Would buy another but need a smaller 3.5MM adapter.

Cassia Hunt: Had this a couple of days now and so far so good. Super easy to use, three buttons that do different things depending on how you press them. Connected to my iPhone easily enough and auto connects when turned on.

Sound quality was perfect. Had been using a Bluetooth and FM receiver to send music to the car which had static, this was clear with no background noise. Also my phone volume was fully up which meant I had to turn the car volume way down, this gives me confidence in the power output of the device.

Nice and small, sits in my cars aux port without really being noticed.

So overall really happy with it, it’s small, simple and effective. Now I don’t have to mess around with the iPhone dongles when listening to music in my car.

Only small issue is the language on the device is not English, but it’s no big issue as I assume the device is telling me it is “powering on” or “searching for device”, otherwise as long as the sound continues to come through I don’t need any more commentary.

Anthem2010: This little bluetooth adapter saved me over $50 so I wouldn't have to pay for the Bluetooth version of my favorite headset brand. The sound is identical to if it were directly plugged in and the buttons on the adapter make voice and volume control easy. Pairing and connecting to multiple devices is seamless with the given directions, and though it originally spoke Chinese, pressing the call button twice changes it to English.

One thing I would change is the volume buttons because you have to hold them down to change the volume rather than just pressing the buttons. I would swap the controls so a long press will switch to the next or previous track and a single press will adjust the volume.

The only other issue I found was the volume dial on my Steelseries headset. I am usually able to use a dial on my headset to adjust the volume very easily, but bluetooth seems to impair that feature. Not a huge deal and not entirely the adapter's fault, so I would still give the adapter five stars.
