Depends on the headphones you're driving, and the source. Certain high end headphones (fancier Beyerdynamics models) do indeed need the amplication from certain sources. In this case, since OP has impaired hearing, it would help drive his headphones harder, but whether or not they'd be driven too hard at high volume is a concern since the drivers would get wrecked if pushed too hard!
@Edwardstorm, ok thanks for clarifying, and this is the model I ordered in the end.

I can also tell a qualitative difference, but rigging up an ABX testing environment would be prohibitively expensive and time consuming (try to design a protocol around this and you will quickly realise why).
I had exactly the same situation as you. Get a pair of closed headphones. They work perfectly. I had a pair of AKG K271 and they worked great. Not too expensive either.
Also you might want to try running your kit through a laptop with a MIDI adaptor and using software like EzDrummer to generate the sound. They record samples of different drums at different velocities from multiple mic positions and it sounds far better than the synthesized stuff coming out of your electronic drum brain.
I changed headsets recently and was suprised at how much louder the new ones sounded. These were both in ear bud type headsets nothing special no amplification. Actually on the older headset I did buy a separate amplifier, with the new headset no need for it. So might be worth a try to go to a store and plug in different earsets and/or headphones to see if one gets you the volume you want without having to purchase an amplifier.
