Great

I find them very good I use these with my Quite on ear piece, to help me sleep better at night.

Works well, I was relieved

When I saw QuietOn sleep ear phones had been sold to a Canadian company I was worried about getting ear foam replacements, I was not sure what I was going to get with Comply. It has been a pleasant surprise, the replacement foam ear tips are better than the originals, better fit, better sound barrier as well. Thanks!!!

Excellent

Stop looking, you found the one!

After trying several other brands, the Comply tips are the best I’ve found so far.
Very easy to get a good seal, and extremely comfortable.
Highly Recommend!

Take care to the size !

I normally use the M size but with my Degauss Lab 12 drives it was awful, no bass and more wind noise than music. I had to order the L size which is better but the difference between M and L is really thin, should be a bit bigger !

I ordered also the 400 series for my Degauss Lab Noir and in between the order and the reception of them my Noir died. I sent a mail to Comply to change the order without any reply from them and I received the useless 400 after few days. In the order confirmation they write to inform when sending, never seen that !
3 starts because all that stuff and not really long lasting foam.
Recommend because of the comfort and sound quality.
