I just received the Sennheiser HD 439 and have run into a little issue.
When playing certain songs with low frequency bass it will cause an annoying rattling sound.
Is there a way to get rid of this issue?
Is this normal with these headphones because I don't get this issue with the JVC HA-RX700s or AKG K81 DJs.
I haven't even tried doing the tape mod yet.
I used the quality test from this site and the very beginning and end causes rattling even at moderate volumes.
I tried the same test on my JVC HA-RX700s and even at max volume with the lower 30 and 60 frequencies set to +20db on my EQ it does not rattle at all.
I took off the pads to my HD 439s and didn't see any hairs stuck inside or anything else that could cause the rattling.
It rattles on both cups.
