After considering different options for headseats and comparing models, shapes, sizes and price points, at the end I decided to convert my Bose QC25 music headphones into a flying headset. I'm very happy with the results and wanted to share my experience.There are a few microphone/cable attachments from different brands that allow you to use noise canceling music headphones in the cockpit. For the most part they are very similar in functionality. I ordered the Crystal Mic because it offers several advantages over the other ones:- The longer headphone cable (I ordered the pro version) allows you to attach the microphone to the right or left cup. On most headphones the cable input is on the left cup and if the mic cable is too short you have to use the mic on the left side (normally when you fly on the right seat you wanna have the mic on the right side of your face).- It uses magnets to hold the microphone in place making it easy to attach and remove.- This guys offer great customer service. If you have any questions or need to get in touch with them for any reason they are very quick to answer and ready for what you need.I highly recommend it. The sound is loud and clear on both ends, and very consistent throughout the entire flight. Everything seems durable and made of quality materials.They sent me the mic in a really nice hard, slim case that wasn't in the item description! I'm able to fit the headphones, mic and cables, and it makes it easy to carry.Basically what I’ve got with this setup is Bose A20-like sound quality for about half the price, and the possiblity of using my ANC headphones for music when flying in the back!I'm very happy with my purchase and will recommend it to my co-workers.Embraer 175 FO.
