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: Good value, works well - Worked well, connected easily to my headphones and a second pair of ear pods so my wife and I could both listen to a movie on a flight. The battery life seems as advertised. I was a good value for the cost and the sound was very clear.

### ⭐⭐⭐⭐⭐ Good value, works well
*by E***3 on July 12, 2026*

Worked well, connected easily to my headphones and a second pair of ear pods so my wife and I could both listen to a movie on a flight. The battery life seems as advertised. I was a good value for the cost and the sound was very clear.

### ⭐⭐⭐⭐⭐ Fast connection. Felt secure
*by A***R on June 15, 2026*

Worked great for the plane. The planes we took for this last trip had the option to connect to their BT network, while everyone was trying to figure that out, I just had to plug this in and start the entertainment. I did worry about the privacy of connecting my BT device to the share plane system. With this I had no worries.
