Review: Worked as intended and a livesave on flights to Auss - Finally got to try this out on four long flights to Auss and back. Paired effortlessly with mu Bose NC headphones with no percevable delay to the sound. Made long flights much more enjoyable (?) With clear sound without the wire getting in the way. I was also surprised at how long the battery listed- not on the full flight but quite a lot of the 23 hrs each way and didn't run out!! Definitely a great buy and is now permanently in my headphones case. Didn't try pairing a second device, will try this next time. Small case to put it in is good too.
Review: Excellent bit of kit. - Excellent little item that worked well with my AKG headphones and was super easy to pair. Excellent battery. Lasted a 12hr flight with lots of charge left. Has two pin adapter for airplane socket too if needed, all packaged in a little pouch for convenience. Highly recommend for the price.

## Questions & Answers

**Q: Will this work with a regular TV?**
A: As long as your TV has an AUX audio output jack, the Relay will work with it.

**Q: Will I get audio lag or lip-sync delays with my headphones?**
A: Your headphones must support either aptX Low Latency or aptX Adaptive in order to eliminate audio latency. Please note that most true wireless earbuds (such as AirPods) do not currently support these audio codecs.

**Q: How are the volume levels?**
A: You should be able to reach sufficient volume levels by adjusting the volume on both the Relay, your headphones, and / or the audio source.

**Q: How long does it take to fully charge the adapter?**
A: It only takes 1.5 hours to fully charge the adapter.

**Q: Can I connect my phone to the Relay via Bluetooth?**
A: No, as a transmitter, the Relay is designed to only connect to audio devices (such as your headphones or AirPods) via Bluetooth.

### ⭐⭐⭐⭐ Great gadget for travel
*by O***R on 8 November 2025*

Really handy to have a Bluetooth transmitter for in-flight entertainment so you can use your wireless earphones/headphones. The option to pair a second device and watch a film together is nice too, though we haven't actually done that beyond testing. Some airlines have a 'watch together' feature though, which eliminates the need, and better syncs video too so you're still watching your own screen, and have independent volume control. Pairing was smooth, but (re-)connecting can be a bit flakey, and a dance of disabling Bluetooth on your phone or whatever else might've connected. To some extent that is just Bluetooth, but there's not really a good excuse for it not taking over once the audio's playing. Nicer feel & design than other Avantree models, and the inclusion of a short USB cable to both charge and take audio from IFE is a nice touch.
