Slipstream,
About 30 years ago, it was all I could gather together to buy a good David Clark headset. I still use it. You will never regret buying good quality for such personal equipment. If times are tight, buy used off eBay - a choice not available all those years ago!
Show those of us who you will meet during your flying, that you take seriously our chosen profession, by equipping yourself properly.
If that is not convincing enough, remind yourself that a headset is a vitally important part of the communcation system of the aircraft. It's failure to operate as intended by the design standard could create a safety problem. ATC and pilots can't hear you, you can't hear them, or worse, the mic blocks the frequency open, and nobody can hear anyone else. And, do you want plug non-conforming mystery electronics into someone's many thousand dollar avionics system. When you let the smoke out, you'll probably get the bill! The proper headset will seem cheap then!
If you have to, buy a junk aviation headset. You'll be replacing it in a few years, but it will get you going for a while. I bet though, that you can find a used David Clark for the same price, and you'll appreciate the quality for decades!
Please buy the proper equipment for the task. Your hearing will be properly protected, and everyone else will appreciate your doing things right. A good starting point in aviation.
