I surely would not reccommend it. A headset, apart from letting you hear ATC e.t.c is also there to protect your hearing. I've used mine for about 4 years now, and still nothing wrong with it. So I would 100% reccommend you buy a proper pilots headset.

I did consider that but then I figured that some little foam ear defenders could be worn with the headset to block any damaging volumes out!
I know its a bit of a thrifty solution but its gotta be tried!
