Almost 20 years ago during my airline career, I got assigned a pairing with a fellow by the name of Mike Lackey. Bose corp had just come out with their QC2 noise cancelling stereo headphones, and Mike was tinkering with inventing a microphone apparatus to convert the general public headphones into functional aviation headset. When he finally started selling them, I was one of his first buyers and they sold like crazy because the end result was a lightweight, easy to pack around getup with tremendous fidelity and all day comfort that you could use on the overnights for music and the like. All for about half the price of a conventional headset. The UFlyMike product and company was born.
18 years later and the company keeps growing. There have been a few David vs Goliath skirmishes with the FAA, various airlines, and Bose, who came out with their own aviation specific headset, but happy customers rallied and the company continues to grow. Mike has unfortunately passed, but his son Brandon has carried on the company which manufactures all of its adaptors in the US and has now expanded into using state of the art Sony XM5 headsets for its adapters as well.
My RV-10 has a UFlyMike set at each passenger seat.
