I currently have Audéo V90-312s with a cShell in the left and a Power Dome in the right. The Power Dome is new as of yesterday. So far so good, but a little too soon to know for sure. The unvented Power Dome I’m now wearing seems more occlusive than the cShell in the other ear that has AOV (audiogram-specific) venting.
I’m expecting M90-312 replacements in 10 days or so. I’m expecting to have Power Domes on both sides initially, but if that doesn’t work out for some reason I’d switch to cShells or SlimTips.
I’ve seen close-up pictures of SlimTips and videos of inserting/removing a receiver. I know they can be ordered with various levels of venting, including none. But I’d like to know when one would be indicated instead of a cShell (or a non-custom dome).
