The new bees work fine, a little harder to get a good seal with but I don't think I'd tell the difference in a blind set up. They might make it slightly darker sounding, but that could just be my brain.
Very gentle that u tested this for me!
Today i've tried what people tipped me: make some warm water flow in the ear for like 20/30 secs! Things were a bit better but that feeling was in anyway but it's reduced if i wear the in-ear with the cable around, dunno why.
Hope i can have a good seal that guarantees me a good sound when i get my zsr.
