    Got it to link my inexpensive headphones to my Tv. I’m not very technical but it took less than 5mins to install and the sound is excellent .It’s small so doesn’t take any space up and you don’t see it!

    Super pareil pour cette télé en Bluetooth, et j’en remercie car j’en pouvais plus. Je suis actuellement ma belle-mère AG en pension pour plusieurs mois et elle est assise nous sur une chaise ( c’est son choix) et elle devient sourd , grâce à ce boîtier, j’ai pu mettre une enceinte connectée à côté d’elle baisser le son de la télé🤣🤣

    Amazingly helpful
    Amazing device! I have a smart tv but it doesn’t have Bluetooth and this allows me to watch tv late at night without worrying about keeping apartment neighbors up.It was so simple to setup as well- only downside is that my xbox360 volume isn’t compatible and doesn’t work with device but it’s an old game system so understandable. All other devices and tv work perfectly! Great price and good device.

    Low Latency Not low to me.
    Like the product. Big complaint. Low Latency I would not say it’s Low Latency. I found it very bothersome.Not a problem if you turn off the sound from the TV and just use the headphones. But the mouth sink will be off a bit.

    Is better than I hoped it would be
    I was in need of a bluetooth transmitter that had optical and line in, as well as be able to connect 2 devices at once. Looks like I found one of the better ones. Pairing was a breeze… after I found out the power adapter I tried to use wasn’t powerful enough. You’re going to need a decent power plug. Otherwise you’ll be sitting there wondering if something is wrong. It just needs MORE POWER! hehUsing the line in hooked up to the headphones output on my stereo. Mine doesn’t have rca out, nor any other way but headphones output. It’s one of those cheap combo stereos.It really works great!I’ve used a couple other Bluetooth transmitters and they didn’t sound anywhere near as good as this one. The bonus of aptx adaptive is a huge plus. That works with my new Heavys headphones. The latency isn’t noticeable to me at all. It’s even better using the optical input. It’s crisp. It’s clear.This simple transmitter is a fantastic, simple, and inexpensive upgrade. It’s well worth it in my opinion.

    The unit works with Bluetooth headphones without issue.
    I added this box to a bedroom TV that supported optical sound. The kit included an optical cable and a USB A to C cable. The unit was plugged into a USB A port on the existing wall outlet. The pairing went without a hitch and works well with Active Noise Cancelling.

    Replaced unit works well
    I purchased one and it arrived DOA. The replacement unit works. There is a big issue with the sticker that covers the display. It has a QR code to get clearer instructions for set up. I recommend using this code and remove the sticker before setting up.I saw one review where a guy thought the unit he received was not the same product. His photo showed the sticker still in place. While the sticker is a great idea, it is not transparent and you can’t tell what’s going on if it is still in place. A great idea that must be causing a lot of returns and support calls.The downside to this product is that it defaults to optical input. If there is no audio coming from the source, it will switch back to optical from the Aux input. When audio begins, it takes some time for the device to switch to Aux causing no audio at the start of a song or TV show. This is the reason for my 4 stars. If they only detected the presence of an Aux when you plug it in, then there would be no input switching going on causing the delay at the start of an audio signal.The other issue I have is that the latency is not low enough to keep the audio synced with the video while using with TV shows. The product states low-latency, but it’s not low enough.

    Solves audio lag
    I had pretty bad audio lag with my new BT 5.3 Space One headphones using a BT 5.0 transmitter. Switched to a cheap allegedly BT 5.3 one and the lag was only less bad. This device delivered near zero lag with solid connectivity. One touch pairing works. Reconnects immediately when you turn headphones back on.
