Just went down the aliexpress rabbit hole again. Theres really everythinf for some of really niche things that i wouldnt ever buy, but some things really do look appealing. I wonder what do you guys use daily thats worth lets say under $20

It’s actually because I work in a high noise environment that I got into bone-conduction headphones. They still work when you’re wearing earplugs.
Nvr thought of that but wouldnt good earbuds with active noise canceling be better for you?
No, it wouldn’t. When I say I work in a high noise environment I mean that I’m surrounded by enough machine noise that I wear ear plugs to protect my hearing. Active noise cancellation isn’t a substitute for actual PPE. It’d be cool if it worked that way, but sadly not.
Bone conduction works great with earplugs though. The only minor downside is that earplugs make the bass frequencies stronger, so I need to open up the EQ settings and tweak things a bit if I’m listening to music, but that’s not really a big deal. I’m usually listing to podcasts or audio books at work anyway.
I don’t think that they would be able to cancel the noise of an industrial environment and it would end up being a case of blasting sound into your ears to try and cover up the noise.
These with ear protection saves your ears a lot more.
ANC plays the inverse of the soundwaves. So a loud noise isn’t made safe, it is just made inaudible and just as loud and harmful.
They are not safety products, only sound deadening earplugs or muffs do that.
Don’t the soundwaves cancel each other out?
Anyway my bigger fear would be a short hiccup or outright malfunction and suddenly you stand unprotected within loud machines.
They do, but not in the intuitive way one would think. They work because there’s a passive seal around the hearing, thus the headphones only have to cancel the smaller amount of noise that gets into your ear, not the full loud noise outside in the environment. This is why ANC need to have mics inside your ears.
The problem is actually that the louder the noise, the louder the noise canceling would have to be. And at a certain point the passive seal cannot stop much of the outside noise, and if poorly designed, if the speaker tries to cancel that noise, it would be blasting massive soundwaves into your ears. But most consumer speakers can’t achieve that and don’t even try. So after a certain threshold, they won’t work and can’t help you with the noise. And the passive noise block is not even remotely good enough as a straight up earplug. So they are not considered protective gear, at least not the consumer devices, only aviation grade ANC is considered protective gear. But you’ll see that they have massive ear cover,s with huge speakers and drivers, and elastic tensors on the headband to absolutely seal your ears and some truly state of the art audio processing that would make the most snob audiophile blush in envy.
They do make some of those for ground crews, construction sites and heavy machinery, but they insists that they are only effective if paired with a sound baffle earplug.
Noise cancelling earbuds or similar do not protect your hearing.
They do not make a loud noise quiet. It does not matter if they are working or not. All they do is make noise seem quiet, you are still being exposed to the same level of noise.
Do you have sources backing your claim?
Here is one backing mine: https://hillhearbetter.com/do-noise-cancelling-headphones-protect-hearing/
that’s … not how science works
