Then perhaps you should read any of the many reviews by people who have had preproduction units... They pretty strongly lean towards them being comfortable and hard to dislodge - to a surprising extent. Tests in reviews I've seen have included running, dancing, headbanging, and jumping up and down intentionally trying to dislodge them.

Seems that the fact there's no cord to pull on them, and all of the mass is inside your ear makes them pretty stable.

I didn't see preprod reviews. I'll dig for it.
