Questions IEMs

[cloudff7]

1) If I store them near devices that emit magnetism, such as 29" CRT TVs and HDDs, will this cause the demagnetization of the dual magnetic dynamic drivers of these IEMs?

2) What material are the eartips of these IEMs made of? Do the eartips melt and stick to the surface of the IEM body after long-term storage for many years?

3) What is the maximum temperature and humidity allowed for long-term storage of these IEMs without degradation of the diaphragm and dual magnetic dynamic driver? here home is varies 34-36C 59-70%

i have kz edx pro and kz edc pro

1. No.

2. The materials vary. There are silicone tips, foam tips, rubber tips, etc. I haven't seen ear tips melt like you describe.

3. What you mention is a normal temperature and humidity range; those are not extreme circumstances.

It sounds like you're describing the soft-touch rubber on computer mice, and the underside of mouse pads.

The answer is no.

I didn't know that IEMs were so fragile to humidity. I have the KZ EDX Pro and the KZ EDC Pro and here the humidity is high, ranging from 60-71% to 34-36C.

1: Nope, no need to worry about that

2: Basically all IEM makers use silicone eartips, there are foam and rubber, but they are much less common and the kind of thing you need to order separately

3: It varies by IEM, moondrop has had moisture issues with their nozzle filters for quite some time, and i have held off recommending their IEM's before when people are in humid climates, with KZ IEM's they're going to break long before moisture or magnetism can cause any effect (and that would take years in the case of magnetism)

1 What happens with demagnetization in the case of 29" CRT TVs and HDDs near the KZ EDX Pro and KZ EDC Pro IEMs?

2 Yes, KZ EDC Pro and KZ EDX Pro use silicone eartips. Is this good or bad for storage? Does it melt?

3 Have you had experience with the Moondrop? Did it present driver defects caused by humidity and storage temperature? What happens with these KZ models?

1: Demagnetisation is not an issue, i keep quite a few of my headphones and iem's in close proximity to my desktop speakers, nothing has happened in all the years i've stored them in this way

2: Silicone eartips don't melt, unless they are on fire i guess, the type of silicone that is used in IEM's is quite heat resistant and doesn't go bad in storage like rubber does, all types of eartips are fine for storage though, it isn't like headphones where earpads can be worn down by improper storage

3: I don't live in a humid place, so my Moondrop IEM's, the Chu, Chu2 and Aria (Aria being one of the most notorious for moisture issues) haven't had any issues in the time i've owned them, i have owned several pairs of KZ IEM's (iirc it's 4 over the years) and only 1 pair still works today, they're just not a particularly good option for super budget IEM's anymore, nothing wrong with owning them, the only way your IEM journey can go is up

I live in an extremely humid and hot place. I've had my Chu 2's for well over a year. The filters clogged once, but guess what? They are user replaceable/cleanable. Took me all of 2 minutes to take the fiter out and wipe it down with alcohol. Back to new.

kz edx pro and kz edc pro use dual magnetic dynamic driver, are these drivers sensitive and suffer degradation at high average 59%-70% high temperature 34-36C?
