Best inexpensive headphones for drummers

My son is a drummer and needs a set of headphones that will block some of his drum sound so that he can hear the song he's trying to learn on his iPod or stereo while he's playing. What's a good recommendation for a good price -- maybe about $30?

i got a pair of these:

that'd be more than 30 bucks there cactus....

I use Yamaha RH-5Ma cans... About $30  here

I really like my $15 set of Creative EP-630 ear buds here

The buds are my favorites, they were $80 when I got the first set..... very comfortable and the sound easily compares to headphones in the $200 to $300 price range. I compared them recently at a music store....and did not see enough of a difference to warrant buying the cans. The guy behind the counter agreed that the buds were very comparable and wanted to know the model.

Thanks for all the suggestions so far. I should have mentioned he does not like the noise isolation type earbuds, with silicon tips. He likes and keeps borrowing my Sony MDR-V700 cans, and that's gotta stop! :) But they're a little pricey. Now Cactus' suggestion above with noise isolating cans and regular earbuds might do the trick, but a descent set of isolating type headphones might be more convenient. I've seen some AKGs in music stores on sale for about $30 before, but don't know how well they isolate, or how good they are.

The Creative Ep-630's are noise isolation buds................they are not at all like the el-cheapo buds that come with most Ipods.

They have 3 different sized soft rubber cups that are easily changed to the size that works best for you. With the proper size cups, they seal exceptionally well to keep the outside noise down, and that also improves the bass response tremendously.

When I said the sound quality compared favorably with the higher priced headphones, I was not kidding and that is due to the noise canceling and bass response from the exceptional seal you get from the cups.

Basically if a set of headphones is closed back with no vent porting it will probably do some isolation.
Drums are very loud when played full out and you stand a chance of damaging your hearing by turning up non isolating cans to loud. Your hearing is worth a lot more than $30 , so I would go for a full isolating type.
Those Leafblowers models are certainly certified to do the job. Then you can put just about anything in there I guess. I'm even thinking you could remove the speakers from a damaged set of phones ( I got lots of those) and somehow mount them inside the hardware store cans. ( silicone?) Hmmm..$14.00 cool.

Another thing to remember is it is recommended you never use any type of in ear buds with out protection circuits ( re = compressor) - in line with them. They too can damage your hearing if misused.

These are great on the cheap: http://www.itrstudio.com/moreme.html

1 More tripple drivers are the eabruds specially made for drummers. Or you can check audio technica M50x as well. Sennheiser urbanite would be a great choice. So any one of the above mentioned will never disappoint your son.
