I would buy the best ANR headset on the market - you'll have to do your own research on which that would be.
Your concentration level will be reduced less - I bought mine at the end of my CPL training and wished I had gotten a decent one from the outset.
Your budget won't cut it; double it at the very least. Take it out of the pilot watch/gold epaulette/GPS account. They won't help make you a good pilot; a decent long lived headset will. IMO.
Good luck!
