Right I was wondering, what is the best way of stopping a click track leaking from headphones onto drum overheads? I have a pair of DT100s and DT770s if that is any help.
You could try in-ear monitors with the Beyers on over them. I don't know what you're using as a click, but a lower frequency click will have less carrying power.
You might do a search on this subject. Different types of headphones/techniques to remedy this problem have been previously discussed.
