– Review for Bluetooth 5.3 Transmitter/Receiver for up to 2 AirPods /2 Other Headphones,with 3.5mm Jack AUX Adapter for Gym Equipment,TVs,Car System,Gaming Consoles and Speaker/Phone/Tablet/PC/Home Stereo || Price: £18.99 (at time of ordering) –
This handy little gadget is a must have for flying with wireless headphones. I was so gutted after spending so much money on AirPods to jump on a plane and discover you can't actually use them with the inflight system. This fixes that by plugging into the headphone jack, and wirelessly sending the transmission to your headphones.
It's very lightweight and in all honesty does feel a little plasticky/junky, but it works and that's the main thing! It's also significantly cheaper than the AirFly one I had originally (turns out that didn't work with AirPod Pros).
A great bargain and an essential item for long haul flights. Recommended.

Some devices already allow you to share audio between more than one Bluetooth device, others say you can but will only allow it if you spent hundreds of pounds on their brand of earpods so this fixes a few problems when its not possible to do this on your own. Yes its a separate device but its not overly big, its easily carried around and its fairly straightforward to use. I wasn't sure how it would work being a transmitter as you can't "see" what you are pairing to but I think so long as you don't have a really old set of headphones that need a PIN or something then you should be OK. Not used in anger or for anything that really mattered about sound quality but it didn't drop out and was good enough for watching a movie on a tablet between two kids.

The 'Bluetooth 5.3 Transmitter/Receiver for up to 2 AirPods /2 Other Headphones, with 3.5mm Jack AUX Adapter' arrived in a printed box that also contained a USB A to USB C charging lead, protective connector cap and instructions.
I connected the Bluetooth device to my audio splitter by using the in-built jack lead. I then switched the device into transmit mode, and connected to an external Bluetooth speaker which again normally has no sync issues. Watching video playback resulted in a perceptible audio sync issue.
As video playback is my primary use, unfortunately I find this device unsuitable and can only give it 3 stars.

I recently picked up the Bluetooth 5.3 Transmitter/Receiver, and it's been a game changer. It supports up to 2 AirPods or other headphones simultaneously and comes with a 3.5mm AUX adapter. Perfect for gym equipment, TVs, car systems, gaming consoles, and various audio setups. Connectivity is smooth, and the audio quality is excellent. Definitely recommend for anyone looking to upgrade their wireless audio experience!

Not the best construction, it feels rather cheap and plasticky, but it does work very well!
This is being used with a record player and Bluetooth headphones and it does an excellent job of not annoying the neighbours. Bluetooth has a processing delay that leads to lip-synch issues when watching video, so devices of this type are best for audio only.
Setup was easy enough; the instructions are minimal but adequate. Range is also pretty good, you can use it one room over, but multiple thick brick walls will cause problems.
Recommended.

Unlike many Bluetooth adapters this is both a receiver and transmitter, selected by a switch on the device. Quality of build is okay but this is a very plastic device, so it feels a little cheap although I do like the addition of a cap for the jack plug. Sound quality is fairly good with no drop-off if used with range. I tested it with my music centre and mobile phone and it worked fine playing and transmitting music. However nowadays its unusual to find devices without Bluetooth, so it's going to be of most use with older devices or devices with poorer Bluetooth conectability. I can for example see this being useful plugged in to a TV, allowing you to listen on Bluetooth earbuds and not disturbing others.

Good for old tech or other devices where bluetooth is just not possible, but can use a standard 3.5mm audio port in either output or input depending on the situation, with a switch to change mode on the unit. Paired quick and easy with tablet and headphones for audio use. It continued to work when connected to a USB power source, so hopefully it will still be powered if the battery runs flat.
Only small thing that could do with improving is that the short audio cable is quite thin, so feels like it could get broken if not careful, a thicker rubber coating would be better to add some rigidity. The package included a manual, a usual USB-C cable and of note, a small cover for the 3.5mm plug, which is a good bit of thoughtfulness from the manufacturer to provide such a thing for when not using the device.

Compact and functional, easy to set up and simple to use, great little thing for sharing music and movies when travelling, plugged it and was immediately showing to connect on my phone, clear sound quality and I have not yet experienced any connectivity issue!
