This video from DJTechTools has some useful advice for protecting your hearing during gigs.
One tip Ean didn't mention is to get a decibel meter app for your phone, and compare it to the Exposure Chart. Decibel 10th is totally free and works great. (iPhone Download, Android Download)
I got custom musician's earplugs through an audiologist/ear doctor, and they've been great so far. Not sure what brand they are, but Etymotic, Sensaphonics, and Westone all offer roughly the same product for the same price ($150). I got the -25 dB filters (~300x attenuation), and it doesn't feel like too much. Very comfortable, and no ringing after events when I wear them. They're useful not only for DJing, but for parties/dances, exercise classes w/ loud music, and when on airplanes (they reduce the noise from the engine and from crying babies, and decrease the pressure changes when the plane is descending.)
The filters stick out of my ears slightly, so on-ear headphones can push on them, pushing the earplugs into my ear canal/eardrum. It starts to hurt after a while, and probably isn't too good for them. Over-ear headphones are much more comfortable to wear with earplugs in. I just got the V-Moda Crossfade M100s, and they don't push on the plugs too much. Upgrading the pads to the thicker XL Memory Cushions ($30) might make them even better.
Check out this DJ Tech Tools video with some tips on how to preserve your hearing and avoid tinnitus.
To find out if you're safe with the weaker plugs, get a decibel meter app for your phone, and compare it to the Exposure Chart. Decibel 10th is totally free and works great. (iPhone Download, Android Download)
I have custom Westone plugs with the -25dB filters, and they've been great.
It appears to be Decibel X https://play.google.com/store/apps/details?id=com.skypaw.decibel

Thanks for the info. I'm not 14. But I'm young at heart :-)
There are db apps you can download to your phone. I use one called Decibel 10 (a.k.a. Decibel X).

What brand & model headphones do you have? I am always looking for something that is truly loud. The Sennheiser 569 I have that reviews said were loud, for me, are just barely audible.
