Hey fellas.
Kind of in a bind with band recording. I've got a garage band who don't get together often, so what we wind up having to do... well I have to write all the guitar tracks at home and I bring them to the sessions.
Drummer has a hard time listening to the tracks and jamming along with them, without his drums drowning the recording out.
He needs to be able to listen to the tracks while cancelling the sound of his drums outside of the headphones. I can manage to loop his mic'd drums back through the headphones so that he can hear what he's doing live side by side with the guitar, so hearing himself faintly outside the phones is not a requirement whatsoever.
Just need absolute isolation. The other part of this is, affordability. Audio quality is not an issue. Consumer grade audio, professional isolation. Any product recommendations around or under $150? Really appreciate any help or purchasing advise.
It's probably my fault, but I don't exactly* get how practice is done as far as exactly where by whom, and same for when together, just two of you, then more of you, etc. Not that it matters at all to help you, just sayin'.
Budget and 100db is kinda silly. In fact, 100 db even without thinking of budget could end up silly. Not that I'm an expert by any means.
The only way you'll get even remotely close is to use both earplugs AND headphones.
Frankly, I would splurge for musician's earplugs, I know you said SQ doesn't matter, but might as well, and in the end the cost may balance out because they're not disposable. You get them custom molded. They will have tiny modules that are swappable so that you can change DB level, all the while maintaining a flatter EQ than other types. Not terribly cheap, but price is not the key to quality in the end, it's the person making the molds. Ask what the highest level of protection is when looking around. Budget close to $100, maybe considerably less if you're lucky.
Then on TOP of those, you put on noise cancelling headphones. Here is a mini review of 5 of them. Of course I'd agree with you to sacrifice SQ first for output ability + noise cancellation.

Then thirdly and finally, just have the drummer back it off a tad, play a touch softer. He can try lighter skinnier sticks, maybe "hot rods", or something. MY guess* is he'll have to do this no matter what combo of things you figure.
