I got the AirFly SE not long ago and it works great. If you don’t need it to receive or need to use it with more than one pair of headphones it works just fine and costs half the price of the AirFly pro. I did find the old dual mono connector on a Swiss flight recently but it worked fine in one of those jacks, albeit in mono. I carried a dual mono to stereo adapter for years and never used it so I stopped carrying it. Now I found that I needed it so I guess I’ll start carrying it again.
