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

This is for the mini thumbnail sized SZMDLX USB Bluetooth 5.0 adapter. Virtually no delay in audio receiver mode. I bought this for my 1992 corvette. I just had the original stereo unit serviced and modified to have a 3.5mm headphone jack installed. I then use this BT unit plugged into my usb cigarette lighter adapter, and then the audio cable plugs from the BT unit into the 3.5mm jack added onto my stereo. My 27 year old car is now BT audio capable!The audio receiver delay is so minimal I can even use this BT unit for hands free phone calls - older BT units (4.0 and lower) have a longer receiver audio output delay that you can't use them for phone calls - your voice would be delayed to the caller significantly).I have several older cars that have newer stereos with USB inputs - I am ordering one of these for each of them. Those cars won't even need the 3.5mm jack as this BT unit will transmit received audio directly out the usb port. Such a clean and small design that will modernize any audio system.

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.

Reason for the two stars is this product did not seem to work for me for what ever reason I tried several times again and again and was unable to connect with Bluetooth device after installation on television. I was sent an email from the seller about how to utilize the product and the product just does not work I have tried several several times to get it to connect with no success So there for this product in my opinion is junk and a waste of money

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.

This thing is really awesome. I used it on my old computer so I could take a blue tooth speaker out on my deck to listen to music from my MP3 collection. It has a pretty decent range, considering where my computer was located in the house.
