Save your money for a nice ANR down the road and buy these in the mean time:

CRAZEDpilot CP-1 Aviation Headset Pilot Headset - Aircraft Airplane https://www.amazon.com/dp/B009W797NS

They are close enough to DCs to hold you over until you need ANR. Also buy ANR as soon as you can, it will literally make flying less fatiguing and ATC easier to understand.
