Soft resin earplugs
Have you tried the soft resin (usually orange) shooting earplugs. For me they always reduced noise to near nothing, as they are very maleable and fit super tight in the the ear canal. for me they took all the high end noise out and left just low sounds, which for me tended not to cause ringing. I play in a band also, so understand the tennitis. Tends to get more frequent if you dont find a solution. Good luck.
QUOTE=rainbow-walker;110441]Slightly weird question perhaps, but my new 899 is causing me a bit of tinnitus (I think my age is showing). Is there a simple (or not) way of making it a little bit quieter ?

Dont mind if it involves a little cost.
