I'd also be concerned about, what happens if something goes wrong? What happens if there's some sort of power delivery issue, and the laser burns far too bright just for an instant before dying?

Is that an unfounded concern?



It's analogous to in-ear monitors.

> Most pro-level IEMs are capable of producing SPLs (sound pressure level) well above 120db. A phantom power spike or a microphone falling on the floor can easily produce a signal loud enough to damage your hearing.

The article above recommends putting a brickwall limiter on the monitor mix. However, a brickwall will only do so much for a sudden screech centered at 3kHz, right in the zone where human hearing is the most sensitive. And what if the limiter gets disabled? Murphy's Law guarantees that at some point the safety system will fail.

The only way to guarantee that devices like these won't emit signals which damage your sensory organs is to make them physically incapable of producing such signals.


Computer interfaces are dangerous

I have been wearing headphones a lot recently and I think I got an ear infection from them. I barely slept the last 2 days because my ears are itching so much. Although only when I lay, not when I sit.

And I purposely have been using over-ear headphones rather than in-ear devices, so I thought you do not get an infection from over-ear headphones


I can't use in the ear head phones at all. Ever since I was young they've given me ear infections. They're also terrible for your ear. Your tragus is there to help protect your eardrum from loud noises, among other things. Sticking noise emitting things behind it is a bad idea.

I've been alright with over the ear style ones for the most part. Though I can see why they, noise cancelling ones especially, could cause infections if worn for long periods.

They create moist anaerobic environments liked by a lot of bacteria and because headphones tend to be left around or carried outside, they're not the cleanest things around. So as they sit nice and snug around your ears, bacteria have a nice happy place to live all cuddled up close like to the entrances to your ears.


I mostly don't use ear buds, but when I do/did I'd wipe them with rubbing alcohol before using. Not, like, constantly, but after putting them down for more than a moment, every trip to the gym, etc.


I've been prone to ear and sinus infections since I was a kid. Apparently I have narrow sinuses. I end up with a sinus infection nearly every time I get sick.

To be fair, I find the sound quality lacking on most ear buds, even expensive ones.

When it comes to low frequencies, the size of cone makes a difference. You'll never get the same kind of bass from an earbud as an over the ear headphone or a speaker.

Music just isn't the same without bass or with lackluster bass. Bassvin most tracks is the bridge between melody and rythym and in many genres actually carries the song. If I had a choice between high quality treble and lakcluster bass, like most ear buds offer, despite, marketing and lousy high end with full bass, id' take the latter every time.


It’s not a one to one analogy. Any electronic system can be made to be failsafe. Audio mixing as it exists today doesn’t have an easy failsafe solution to limiting output, but that doesn’t mean such a system couldn’t easily be made. Literally anything you could name that produces or consumes more than 100 kW is failsafe. There is no reason an eye laser couldn’t be as well.


Sure. It's as implausible as (say) your car not starting, or a water pipe bursting, or your phone arriving DOA.

Personally, as cool as it sounds, I'll pass.
