Headset Repair componenents

I have a few sets of headset with bad cables.
Replacing the cable is usually such a high percentage of the value, that
I tend to just buy a new cheap headset.
I have enough laying around, that I would like to just do my own cables.
and not worry about it in the future.

I think I can get the wire from someplace like digikey, and the plugs
are available from multiple resources.
Does anyone here have any recommendations for strain reliefs?
I should be able to come up with something where the cable enters the
headset, but the tough one is at the junction/strain relief box where
the mic, phone, and main cable join. Any input for a suppliers?
