-These are not over the ear headphones. I thought they were advertised as such, but perhaps I was mistaken. You cannot wear glasses with these headphones.
-They fall off your head if you lean over.
-if you adjust the headphones, it often pauses the music when you don't want it to.
the ear cups are too small. Has anyone found replacment ear pads for these headphones?
Somebody can correct me if I am wrong, but I knew that over ear is different than around the ear, and that over ear are a sort of middle way between around the ear and on ear.
If so, these are definitely over ear. They are actually also around the ear if one's ears are less than 5.5cm long (I anyway with 6cm long ears never had any problem).
Thank you for the info about wearing glasses. Some people may not experience the same problem, but it's good to know the risk.
They have never fallen from my average sized head, but the clamping force is indeed gentle.
The headband never caused me any discomfort though. They are also light enough not to give to the headband much burden.
Given that you say they fall from your head I would guess you have a narrow head and therefore the clamping force is not enough and all the weight is on the headband. Good to know. So these are good for people with average to big head, but small ears.
If by "adjust the headphones" you mean pulling them far from your ears to change position, this is due to the head sensor which is meant to pause the music when you wear them off for a while, like to ear what people say to you, or when you just put them down around your neck to do something. It is a very useful function which you can deactivate if you do not want it.
The earcups cannot be replaced

If you are planning to buy a different one you may explain your wished signature and features. Somebody will surely be able to come with a suggestion.
