Question magnetic drivers in phones kz

[solderdude]

but in the case of in-ears (for example EDX Pro and EDC Pro) they have magnets and I don't know what disturbances or conflicts between the magnetism of the 29" CRT TV and the HDDs x in-ear magnets are caused by them being very close

There is absolutely NO danger to IEM's.
Period.....
They will NOT demagnetize near any CRT nor even when laying on top of HDD.

What might happen is that IEM magnets may cause color spots on the screen or when you take the HD apart and put the IEM's on the discs you might erase data on it.

in NO way will the IEM's be damaged.

The biggest enemy of magnets is a high temperature or continuous hammering on it (with great force). For that to happen the temperature of the IEM would need to be so high that all the plastic parts in the IEM would have turned into a puddle (>> 300oC). So... no don't worry about magnets in (even cheap) IEMs.

And if it even were possible.... we're talking about IEM's that cost less than $ 30.-
