Question InEars magnetic driver

[cclassicaran88]

In-Ears headphones use magnetic dynamic drivers. If you bring the in-ears close to an electronic device that releases magnetism with a 29" CRT TV (coils, speaker) turned on, will this TV cause demagnetization or permanent loss of performance of these in-ear drivers?

No.

because?

The field coils surrounding CRTubes are only strong enough to deflect the electron beams that they surround within the tube - they won't demagnetise the magnets in nearby earphones.
(Otherwise the magnets on the TVs own internal speakers would be first to suffer 😉).
