For the most part, to listen to Air Traffic Control and ATIS, and to numb some of the ambient sounds (dogs barking), I use a David Clark aviation headset (model H10 13-S) which is a left over from when I did my PPL (private pilots license). This particular headset is a marvel of engineering and works exceptionally well for real world flying and simulator use.
Recently, I saw for sale in a wrecking yard, an “airliner style” Telex Airman 750 headset. The price was $30.00 including freight from the USA to Australia. To be honest, I wasn’t expecting too much – after all, what does one get for $30.00 these days! I was pleasantly surprised when I opened the FEDEX sachet and an almost brand new headset, equipped with boom mike and tell-tail “aviation style” audio connectors and cable, fell on the floor. The foam ear pieces were still good condition, as was the small clip that attached the cable to your collar (to stop the cable from snagging).
After plugging in the headset to the Flight Sound X Adapter (click to see earlier review), I was even more surprised when the headset worked! Sounds were crisp and easy to hear and the weight of the headset minimal. The boom mike relayed my voice more than adequately across the network to VATSIM.
Using real aircraft parts adds to the realism of flight simulator; a headset being just one item. I guess sometimes bargains are still to be found!
