Review: Ideal for flying with bluetooth headphones; a well thought out product - Why did I buy this product? Because I make international flights on a regular basis. For travel, noise canceling headphones are a must-have, but most are now bluetooth. Unfortunately, most cattle class seats have infotainment systems that only provide mini-jack outputs. Enter this device as the perfect solution! At least in my opinion. This device allows me to plug-in to the output jack on an aircraft without the inconvenience of wires. It has several domestic uses, specifically provided a bluetooth interface to older audio equipment, PC's that don't have bluetooth, and (some) tablets. Does it work? Yes, no reservations. Fully charged, the battery was only 50% drained at the end of a 10 hour flight to London from Phoenix, AZ. I used this device in conjunction with my iPad mini, the aircraft infotainment system and even my PC at home. Binding was fast and effortless. Recommend you read the instructions because although binding and unbinding is easy (and works) the unit itself has a minimum of controls and you need to know what you're doing! I really can't speak to quality or range, but at least up to around ten to fifteen feet it was working fine, and sound quality was excellent without drop-out or interference. Can I listen to music while the unit is attached to a charger? Yes you can. This was a worry for me, especially since I forgot to recharge before the return trip. So I attached to a USB-C power bank and absolutely no problem, throughout charging, the unit worked fine. BTW, many airlines seem to be banning the use of power banks on or onto their aircraft - just another nuisance to check on before you fly! Do I know how much power is left? Yes, there are 4 white LED's which tell you how much charge you've got on the device. The top-most illuminated LED flashes until the next level is reached or the unit is fully charged. Finally, can two people listen to the same audio? Yes, my wife and I watched a video on the plane, with both of us wearing Bose NC headphones in bluetooth mode. The unit provides two, simultaneous links so for me that was the final box ticked. Some widgets are hard to use, but this one is well thought out and easy.
Review: Relay works well plugged into airplane IFE and computer headphone port - Relay set-up wouldn't complete the connection at first; however, when I first used it on the airplane, it worked perfectly and was easy to use. Just plugged it into the airplane IFE and it connected automatically to my headphones.

## Features

- 【FOR In-Flight Wireless Listening】For travelers who want to use Bluetooth headphones with airplane seat 3.5mm audio jacks, without cables. Designed specifically for airplanes, seatback screens, and other 3.5mm audio-out sources – not phones or instruments.
- 【Stable Audio For Movies & TV】Uses a Qualcomm Bluetooth platform for reliable, interference-resistant audio during long flights. When paired with aptX Adaptive headphones, video and dialogue stay well aligned for movies and TV shows.
- 【Dual Headphones, One Source】Connect two Bluetooth headphones at the same time to share in-flight movies or music. Audio stays synchronized between both listeners, making it ideal for couples or family travel.
- 【NOT FOR Real-Time Or Instrument Use】NOT for musicians, gaming, live monitoring, karaoke, or electronic instruments. Bluetooth transmission introduces delay that makes real-time performance or rhythm-critical use unusable, even though audio quality itself is stable.
- 【LIMITED Bluetooth Behavior & Latency】Relay is a transmitter only and pairs only with headphones, not phones or tablets. Bluetooth must be turned off on previously paired devices to avoid auto-connection issues. Latency depends on headphones:aptX Adaptive ≈ low delay; Standard Bluetooth ≈ 150–200ms (lip-sync may be noticeable)

### ⭐⭐⭐⭐⭐ Relay works well plugged into airplane IFE and computer headphone port
*by A***R on January 5, 2026*

### ⭐⭐⭐⭐⭐ High-Quality Bluetooth Transmitter with Crystal-Clear Sound
*by C***S on September 30, 2025*

This is an excellent Bluetooth transmitter that delivers impressive sound quality, not only for headphones but also for portable speakers and even soundbars. I tested it with a pair of TOZO headphones, and the sound was crystal clear with no noticeable delay while watching TV. I also tried it with Soundcore headphones, a JBL portable speaker, and my Sony soundbar, all worked flawlessly with excellent audio quality. One feature I really appreciate is the ability to switch between two connected devices. With a simple press of the center button, you can easily alternate between them, which is very convenient. Yes, this transmitter is priced higher than many cheaper alternatives, but after trying less expensive brands, I can say the difference is clear. Those budget options often struggle to work well with soundbars or portable speakers and don’t offer the same clarity. If you want reliable performance and excellent audio quality, this transmitter is well worth the investment.
