Upgraded Bluetooth 5.3 Transmitter 3-in-1, Portable Wireless Rechargeable Transceiver Adapter for TV PC, Stereo Audio Receiver for Car Speaker System

This product does it's job as advertised. I can both send and receive bluetooth audio (though not both at the same time).This is great for using my non-bluetooth headphones with my iphone. I was pretty upset when apple did away with the 3.8mm jack. This handy device allows me to use some of my better wired headphones so I can bop around the city looking like a character from the 80's. It also allows me to use airpods with my old clickwheel ipod classic when I want to listen to music on a superior device and not have to be tethered in.As with any bluetooth device, there's a slight loss of audio quality. It's not noticeable unless you were to directly compare this between the same exact headset/speaker hardwired into your device. This isn't a shortcoming of the receiver, just something that happens with bluetooth overall.There is also a slight delay. I've played music over my stereo and plugged this into the headphone port to transmit the audio to a bluetooth speaker in another room. When walking between the rooms you can hear that there is a noticeable lag in the audio of probably 200ms or so. This isn't an issue if you're just listening over headphones and the lag is short enough that it wouldn't even make a difference if you were watching a movie, but I wouldn't use this if I was scoring a film which relies on getting audio to sync precisely at a frame by frame resolution. Then again, if you're scoring a film, why are you using bluetooth?All in all, great device. I was impressed enough to buy one for my girlfriend as well.

It works amazing easy to take on the go and use anywhere. I bought it to wireless play music from my Ds lite hand held console and Gameboy Advance SP. For the Gameboy Advance sp I have type c port for charging and use audio jack type c dongle.

This product works great for non real time audio where latency is not an issue. Sound quality is great. Pairing is flawless (at least for the Apple Ear Buds). But ... for real time audio as in a studio situation, there's at least a 50 msec delay, maybe more as I had no way to measure (and I spent little time checking further after I noticed the delay). Using to monitor an instrument or vocal in real time just does not work. There does not seem to be any way to reduce the buffer size and therefore delay. I will keep looking. My fault for this ..... for not checking so it will just go in a drawer and maybe be used for some future one-off application. Thought I'd let you know.

This product does not work with the radio in my 2018 Lincoln Premere and likely would not work in other Ford products manufactured around that time. I suspect that many other cars of this vintage would use the same Bluetooth system. My radio's Bluetooth had no problems with other devices. I did a download to update my Lincoln radio's Bluetooth which continued to work with my iPods and iPhone and even my Kindle Fire but continued to report that this device could not synch. I would caution the buyer to test the unit right away so that it can be returned before the refund time limit is up. I bought it because it was cheap. You get what you pay for.

I bought this for our bedroom tv which has no blue tooth connection. It connects my wireless earbuds just fine.

I charged the device as soon as I unpacked it. Charged up fairly quickly. Bluetooth connected fairly easily to my Skullcandy Grind True Wireless earbuds. Connection seems solid. I can hear a little electrical interference, especially when I put my hands on or around the device. I bought this especially for use with my Audiovox portable DVD player that I've had for many years, and it is rock solid but lacks wireless capability. So, I decided to try this route to free myself from the last vestiges of wired earbuds/headsets as I'm spoiled to wireless. I don't want to, nor do I need to replace my DVD player, it was a birthday present from my beloved wife, it works great, and has a great 10" screen, a battery, car plug, and mains power supply. Really great when sitting, as I recently had to for 4 hours, in a long line that isn't moving!Back to the device: it functions well and as advertised in a nice small, lightweight package, and includes the necessary cables, but lacks any kind of pouch or case - which I like to have for my small devices, especially multi piece.I got everything connected, and it works ok except the volume, at full volume setting on the player and device, are so low that any noise in the area, including low volume conversation, makes hearing the DVD dialogue. For some reason, the dialogue is distinctly ''layered" where you can most clearly hear the primary character(s) dialogue, then there's a distinct drop off in volume in "support/background" character(s) dialogue. If you adjust the volume downwards, at all, you hear nothing. I tried adjusting volume on the device, but it doesn't respond, and same for the Skullcandy earbuds volume control. I have another set of wireless earbuds, generic brand, and got the same results.Only time I can possibly use will be late night when other household members are sleeping. I am disappointed with this.TLDR ; Seems to be well made. Functions well. Except poor volume level.

I bought this years ago and after figuring out how it works, it is just what I needed. Had an older TV that wasn’t Bluetooth compatible. The charge lasts a good amount of time, the sound is spot on (that depends on your headset as well) and it is user friendly. Great value for what I paid for it.
