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

Needed bluetooth from older tv to a speaker...worked perfect. Awesome little device, did exactly what I needed, connected to the tv, had it set up and working in under a minute. Great price

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.

For the sources I connect to this, there is no volume control needed. Volume is controlled via the connected source. Not a big deal for me, I am sitting right at the source, so volume control is at my fingertips.I get the sound I expect from this device. I receive the Bluetooth with my hearing aids, and what comes out of this transmitter is what I get from anything connected in this way.As with another device like this, I do have to be careful not to walk out of range of the transmitter. If I do, the Bluetooth is disconnected and the connection is forgotten by the device. Not a problem for me. If I get up to walk out of range, I just unplug the device from the source and carry it with me. When I come back to the source, I plug the device back in. Easy workaround. Also, I have discovered how to re-connect the Bluetooth easily if the connection information is lost, so I do not worry anymore if I do something to break the connection.Another such device has a battery life that almost works for the longer sessions I am listening. That is one reason I got this device. If the other device goes dead, I unplug it, put it on charge, and plug in this device. AT LEAST twice the battery life. I do not know the actual battery life of this unit because it is my secondary device. If I run out of battery on both devices, I have been listening too long!!I used to have an old DC plug-in transmitter for my TV. Unfortunately, I need a device for the TV and for a laptop which does not have a great Bluetooth connection with my hearing aids. I really like the battery operation, because I can (and do) swap a single unit between TV and laptop without issue. One Bluetooth connection, regardless of the number of sources.A difference between this and my other such unit is, this one has 2 AUX ports, one for transmit, one for receive. It also, weirdly, has a switch for TX and RX. Not sure why both (switch AND ports), but not an issue for me. My only reason for having these devices is as transmitters. I have never used any such device as a receiver, or needed to.

This is ALMOST a good item for the price. For continuous music, it is fine if your sound quality expectations aren't too high. For movies with continuous sound (e.g., background music when nobody is talking) it is fine. HOWEVER, for quiet movies, it cuts in-and-out. This would be acceptable if it didn't cause the dialogue to be clipped. It's super annoying! What was that first word spoken by the character? I'll never know. Rewinding doesn't help, because there is always the quiet part that turns off the sound before the spoken word.I wish there were a setting to just keep the transmission of sound "on", whenever turned on, even during the quiet parts, so you didn't get the interrupted/clipped sound and dialogue.Also: Don't expect high fidelity sound, but sound quality is 'acceptable' for sitting on a plane and watching movies or listening to background music IF the sound is continuous. But not if there are pauses in the sound, even for a few seconds at a time. There is always some static/noise when it is transmitting sound, so you are very aware when it is transmitting versus when it has paused transmission. Again, kind of annoying.

This product, although it did connect easily enough to multiple Bluetooth devices (which was nice), came with a terrible distortion of the Audio. There was both crackling of the audio output with buzzing noise constantly present.This is was likely due to poor assembly, of the unit itself, as I tested the provided 3.5mm cables (as well as a higher quality cable - purchased separately), with alternative devices for both input and output functionality, and the issue was only present on this device. I also tried several different USB cables just in case.My guess is that the issue was in the 3.5mm Audio Jack (Female) on the receiver/transmitter itself, which was either poorly manufactured and not making a good connection, or was poorly soldered in the wiring.This unfortunately made all other aspects of the product moot points. With an item such as this at such a low cost, I was not expecting the greatest results, but I did not expect the simplest of aspects to be of such poor quality. This may have been due to a bad batch of components, a novice assembler, but it clearly did not receive sufficient QC testing even at a low level.Could it have been damaged in transit? Yes, but the unit was not damaged, it was extremely light, and if the soldering came loose in transit, than the soldering job was sub standard.I could have requested a replacement, it could have been a bad unit that slipped through sub-assembly, but this is literally the simplest part of the product for both assemble and testing.If you are looking for a very cheap alternative to more expensive comparable products, you can give it a try, but I would not expect much here. If you do try it and receive a unit that does not have the same issues I had upon arrival, I feel it is safe to assume the products longevity would be very limited, and failure would be more likely than not to occur especially if you are plugging and unplugging the unit into different devices.Rated a 2-star because Bluetooth connected seamlessly, which was the only plus I can provide it.PASS on this item unless the Manufacturing can resolve such a basic issue.
