    This Relay kit has become an essential part of my travel kit. The Bluetooth adapter is fantastic, especially for long flights and the sound quality is top-notch, giving clear and crisp audio without any noticeable lag.

    One of the best features is its battery life – it lasts throughout my long flights (14hrs plus and it barely went down one bar) without needing a recharge. It’s easy to connect if you follow the instructions and worked perfectly with Apple AirPods.

    Pleasantly surprised, and definitely made long flights more comfortable!

    Does the job well, I had a very slight perceptible delay but then my over ear headphones are not the top of the range. I did forget to turn it off so when I got on my return flight the battery was dead, but I was happy to find out that I could charge it on the plane really fast, and I could use it while charging, so even better! love that it comes with a little zip bag, supper easy to connect. Happy with the purchase.

    It’s apparent that people leaving five star reviews here have a pretty low bar when it comes to quality – latency on this thing is huge, 400ms, and distorts MASSIVELY when there is any loud noise (even when you turn the volume down on the unit – RIGHT down, til it’s barely audible) – sent back

    Fungerar perfekt, supersmidigt! Använde den tillsammans med mina Bose QC Ultra på Emirates Stockholm-Dubai-Bangalore. Batteritiden är grym, och uppkopplingen är stabil, inga problem alls! Rekommenderas varmt om du ska flyga långt!👌

    Works really nicely. Instructions are clear. Thanks for thinking to include a nice little travel bag. Would be five stars, but for the packaging unrecycleable at least in my location.

    Great battery life, easy to pair to two sets of headphones. Charge time is good and good range for the Bluetooth.

    Didn’t pair with phonak hearing aids which is a shame but not main reason for buying and not a problem for me.

    Fingers crossed the build quality will stand the test if time but would buy again if any issues.

    Bit of a lag on tv but nothing too bad, used mainly for sport so doesn’t need to be perfectly synced.

    Testato in aereo, è stato acceso per circa 8 ore e la batteria non è arrivata neanche a metà. Zero latenza audio. La parte migliore viene adesso…me lo sono dimenticato nella tasca dei pantaloni e si è fatto un ciclo di due ore e mezza in lavatrice. Appena tolto giustamente non funzionava. Per farla breve dopo 5 giorni è ripartito come se nulla fosse! Do 5 stelle perché non posso darne 6.

    Battery lasts forever, very easy to connect. Can connect up to 2 headphones. Allows me to use my own headphones on the plane, love them.

    I have flown on BA and United. Both times the supplied two pin adapter has not matched the adapter the airline used. I have tried inserting directly into the hole without an adapter. But i dont find this works reliably

    Imho a broader range of teo pin adapters are needed

    Its a good product. But it can be a tad fiddly to set up. The online instructions accessed via a QR code are very helpful. But remember to do this early. You may struggle with internet access once onboard

    I have been needing a device like this that works, this one actually does work with Apple and Beats products as suggested (other products do not) The sound quality and range of the transmitter is impressive. I don’t like in a mansion or a castle but I can roam my home with ease and keep the connection.
    I highly recommend this product if you value quality and ease of use. I’m currently using the transmitter on a TV so I can work at the computer and listen/watch TV while I work.

    Perfect! Used on my long flight and at home to share the sound on 2 headsets on a tablet/nintento switch (very practical when you have kids).
    Easy setup and use.

    Einfache Bedienung. Klappt alles im Flugzeug. Ist super für alle die lieber ihre Bluetooth Kopfhörer verwenden wollen. Habe es auf mehreren Langstreckenflügen ausprobiert.
