After reading this thread I decided to give the Comply tips a try. I’ve had APP versions 1 and 2 and they never felt really secure in my ears. I frequently had to reseat them as they’d loosen in my ears as I moved around. No way they’d stay in my ears while exercising or working outside around the yards - got some accessory ear hooks which worked OK for that. Tried all the sizes of the original silicone tips.
Now, 2 days in with them Comply tips I’m amazed. Have used them around the house and outside and light exercising. More comfortable than the original tips and not once have I had to reseat them! They continue to be secure in my ears after 2 hours or more.
Yes, they are disposable (not sure yet how long they’ll last with my wear patterns) which makes for a kind of high recurring expense. I’ll probably live with that for the benefits they provide me.
