Bluetooth 5.4 Transmitter Receiver, Airplane Bluetooth Audio Adapter

This is a great bluetooth device which can be used as either a receiver or transmitter for devices which currently lack bluetooth. As either a trasmitter or receiver it must be paired with some smart device like a computer or smartphone or tablet. It can't be used to transmit to bluetooth headphones or earbuds, which is the only downside I can see about this device. Plugging the included connector into the proper connection allows this to serve as either a transmitter such as from a keyboard or guitar to a computer, or a receiver to plug into the AUX input in an amp to stream audio for playing along or just for listening to. The plugs are 1/8" so if you have 1/4" jacks such as some guitars or amps have you'll need to purchase an adapter. The sound quality is excellent and the latency is minimal. And the price is excellent for the ability to use bluetooth!

Update: Was using the transmitter with my Airpods and the Bluetooth kept cutting in and out. One time when it came back, it came back LOUD and since then, the volume has been fine. I am not sure what made the volume raise, but I wanted to update as the device is working great now. Also changing my rating. Will update if the sound gets low again. I had purchased this to listen to my iPod Classic with my AirPods. It connected fine, but the volume is so low that I can barely even hear some songs, even with the volume on the iPod all the way turned up. I had the same issue when I plugged it into a PC as well. It seems to work better as a receiver (for instance if you are plugging it into the aux port on your car or another device). If you are looking for a transmitter, look elsewhere unless you don't mind very quiet audio.

I bought this 2026 Upgraded Bluetooth 5.3 Transmitter hoping to connect it between a walkie talkie and my Bluetooth headphones so I could hear communications more clearly. Unfortunately, it didn’t work as I intended. Functionality: It did not work well for my intended setup. I had trouble getting it to function reliably between devices, and it wasn’t consistent once paired. Battery Life: Battery life seemed decent during the time it was on, but since pairing was inconsistent, it was hard to fully evaluate long-term performance. Portability: Very portable and easy to carry around due to its lightweight design. This is one of its better features. Ease of Use: This was the biggest downside. Pairing was difficult and not consistent every time I tried to connect devices. Latency: I didn’t notice a major latency evaluation in my use case, but overall performance was inconsistent, which made real-time use unreliable. Compact Size: The device is very compact and easy to store or transport, which makes it convenient for travel or small setups. Overall, while the size and portability are great, the pairing difficulty and inconsistent performance made it not suitable for my needs.

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.

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.

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.

I’ve had this pump for a year and it still works great.

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.

I bought this to add bluetooth music streaming to my car. I have used it both with an old Onix smartphone and with an iPhone 8 Plus, and it works well with both. The connection is stable and the music quality is good. The only thing I wish it had was some sort of battery indicator, because I'm never quite sure when the battery will go flat.

Best Part is that the Unit is chargeable. So once it is charged - it is very portable. However, being Bluetooth, there is some lag in receiving/hearing the audio - which for playing/recording musical instruments or recording vocals, would not be suitable.

Excellent product, does it’s intended job perfectly. Highly recommended!!!

Printed manual text is so small, it really is so hard to read; but very clear instructions. Product works great ! Zero regrets !

It does the job well so far. I’ve used it for two weeks every day and I hasn’t skipped a beat. I paired it with my AirPods and worked well. Not the greatest sound quality compared to other BT devices but again, considering its price, it is not bad. It may look a bit cheap made though and it’s not prettiest device to show around.
