A few weeks back I picked up a set of cheap isolation phones. the sound was well rather bad. Weak bass and nasal mids.


I took them apart and found a driver from what looks like an open phone, but it was glued into a closed cup, no wonder everything sounded nasal.

The first thing I did was remove the plastic cover on the driver itself. then I sealed it completely to the earpad/ driver holders. finally I cut 10 1/8" holes in the cup. This woke up the bass and made the mids brighter and mellow. I did sacrifice isolation but the price was worth it for improved sound.

I'll take pics in the morning

next mod to these will be some different damping inside the cups

I did cut the foam this helped brighten the midrange but made the Bass have a tiny bit of echo. I'll be adding some Dynamat to the cups to kill that.

The holes I drilled in the cup were trial and error. I started with one and added holes till the bass didn't sound strangled. So far I have almost $60 in these headphones and 59 of that was buying them. if I ruin them NBD they are dirt cheap and I get to learn how Phones work acoustically.
