SZMDLX USB Bluetooth 5.0+EDR Adapter, Mini Bluetooth Transmitter Receiver, Wireless Audio Adapter with 3.5mm AUX for Car Headphones PC TV Home Stereo, USB Power Supply, No Driver Required

I use a Cowon Plenue D music player. I use it a lot. When I am on long journeys in my car I want to use my music player. I bought a new car that didn't have a 3.5mm aux socket (bad VW, bad VW). I didn't want to link my phone to the car as this would only encourage dangerous driving. My phone is OFF when it's in the car. So what was I to do? I looked on Amazon for a bluetooth to 3.5mm converter without much hope. Eventually I found this device. The price was right so it was worth a punt. What an amazing thing. This is about as big as my thumb nail. It has a USB port and a 3.5mm socket. It's easy to use. Just plug the device into you car's USB port until you see a red light on the device and then wait for your car to connect to it. Plug the supplied 3.5mm male-to-male connector into your music player and off you go. The sound quality is good and the connection via bluetooth is solid and reliable. I had two niggles neither of which is the device' fault. The first is that the USB port in my car is hard to get to so I had to buy a short USB male to female cable. The second is that the supplied 3.5mm male-to-male cable has one jack which is a bit dodgy and kept cutting out. The solution was to turn the cable around. Easy but a bit frustrating to trouble solve on the move. If you have a favourite music player that has a 3.5mm headphone socket and you need to connect it to a bluetooth device I can't think of a better solution. Highly recommended.

It is not usable for computers, which would be anyone's main use for such a device. The fact that it is not stated that it cannot be used on a computer is almost false advertising. This was a waste of my money, and I cannot use it. EDIT: I am increasing my rating to five stars: A representative of the product reached out to me personally and fully refunded the product, as well as offering me a replacement. Despite it not working, I cannot in good conscience leave a low review up: I was well compensated, and they genuinely care that I have a working product. It could be that it just didn't work for me, so on the basis of customer service and a full refund, I would re-rate this five stars. The creator of this product is highly trustworthy.

What a joke!!! This thing came w/one tiny folded up piece of paper smaller than a business card for instructions and was written in broken English. I tried over 3 hours to get it to work and the best I got was having it flash proper color light. No sound at all though. So I looked for tech support and all that was available was a phone number in China (international fees would have cost me around $2.50/minute). Or, an email address. So I emailed them and each time it took around 30+ hours to get a response and they obviously weren't reading my messages because I was super detailed even including the brand and models of equipment I was trying to use device for. Finally after spending a cumulative 6 or so hours running back and forth to check the stupid blinking light on unit and 4 days of waiting for email replies in broken English Amazon allowed a return which meant I had to make a special trip to a UPS store and drop off. I did call Amazon to get an RA label and send back after day 2 but they wouldn't let me return until day 4 because it wasn't something they stocked. So I also had to make 2 calls to Amazon to get return/refund process started. The second Amazon rep was much more accommodating and nicer to deal with as she actually spoke English as a first language. So I ened up buying a 10'cable to make connection for sound. So unless you want one little overpriced blinking light to make a dance club look for some fleas I would look elsewhere. If I could give this negative starts I would. Actually that would be a more interesting rating system if we had an option for at least 1 negative star.

ORIGINAL REVIEW: Very disappointing experience with this USB bluetooth transmitter. The pairing instructions are terrible. I followed them repeatedly and couldn't pair wireless headphones to this device plugged into my smart tv. No further instructions here or online. Had to scour the internet for similar devices hoping to find better pairing instructions. Finally found a note from a different supplier on another website (the younger version of Old Egg) that suggested to turn off smartphone bluetooth first. Did that and was able to pair this device to the headphones quickly. Finally! Unfortunately, the sound quality was not good. Whereas the sound volume was sufficient at 15 using the same headphones with another bluetooth transmitter (or the tv's external speakers), I had to turn the volume up to about 35 to hear the volume with this USB transmitter. I confirmed the dongle and aux cord were well seated in their ports. I feared that the sound might kick-in while wearing the headphones and jump up to the true volume of 35 and blast my eardrums. I had high hopes for this device but sadly am returning it. UPDATE: The seller sent me a replacement and it works better. The pairing was much easier (especially now that I know to turn off other nearby bluetooth devices 1st) and it is working as advertised. It automatically pairs with my wireless headphones whenever I turn them on now. There's a slight delay in the sound from the tv to the wireless headphones, but I think that's pretty normal with wifi sound. The seller provided prompt and professional customer service and made things right.

This was easy to use and works 100% of the time. Unfortunately, the quality is not good enough. The quality is much better via direct aux connection. When I playback through this Bluetooth receiver, the quality drops (treble not as high, bass not as low, flatter dynamic range). For someone without a bass amp, or lower quality audio system it might be good enough. For me, this is only good enough for Podcasts and I might just return it.
