I was intrigued to see a lady at the crosswalk the other day wearing earbuds with thick tubing instead of wires. Googling it, I discovered they were "EMF free headphones". Apparently enough people think electromagnetic radiation in the ears is a problem that there are now dozens of these headphones on the market that put the driver half way along the cord, with tubes proceeding to the earpiece.

> Apparently enough people think electromagnetic radiation in the ears is a problem Even Andrew Huberman, one of the most popular health science podcasters, has dabbled into anti-EMF quackery. On one podcast he claimed that his Bluetooth headphones produced notable "heat effects", implying that the electromagnetic energy was enough to produce palpable heat in his body. It's obviously placebo effect to the extreme (ph…

I've only watched a little bit of Huberman, but I can't take him seriously because:

a) he's obviously done a LOT of steroids or something, which aren't really great for you

b) At least half of what he says appears to be made up woo-woo nonsense

I've never heard this before! When I started flying it was just the 2 mono jacks that you still see on planes that haven't been updated (always wondered why it wasn't just a stereo jack) Pretty surprising to hear there's air/sound tubes rigged on to every seat on a plane. Seems like the sound tubes ended in the 70's: https://apex.aero/articles/sound-tube-surprising-history-air...

In my "maybe I'll need it some day" pile, I still have the two-mono-plugs to one stereo jack adapter I bought at Radio Shack so I could stick it to The Man. I think I only used it half a dozen times.

I bought a BLE wireless headset last year that came with one :-) No idea when I would ever need it!

I thought these were a nice idea when I had my MRI the other day, little did I know that I would barely be able to hear anything over the noise of the MRI machine. Ear plugs were better, kept out the noise of the MRI machine and let me drift into a trance.

I recently got an MRI and the technician asked me what I wanted to listen to on the headphones. I said "Something relaxing, do you have ambient music?". This turned out to be a terrible choice; the music was so quiet I could barely hear it. Earplugs would have been better. I had some in my pocket that I brought but it was too late. So after the claustrophobic panic subsided and I realized I was left in there with not…

This is exactly how I approached it the first time with just the ear plugs. I find those machine sounds can be quite soothing and hypnotic on their own. I’ll give the music a miss next time.

Wear leveling socks is a critical challenge for me. Unlike larger clothes, socks don’t stack easily, so defy conventional methods of stock rotation. How do you approach this? Would it make sense to buy one of those shelf springs that grocery stores use to keep boxes towards the from of the shelf?

You need "Socks as a Service" (we could call it "SaaS") - every day someone drops off a new pair of socks and picks up your previous pair. If you pay for a premium plan then no multi-tenanting and only you get to wear any particular pair of socks.

That sounds intriguing as I like not deciding. On the other hand, I'm sure SaaS has some premium over buying outright. Since I already have the capital outlay of a washer and drier and weekly time blocked for laundry of which socks is a very small percentage, I'm not certain if it would make sense.

On the other hand, if there is a "complete casual work from home uniform" service, that might be worth it as long as some VCs are subsidizing it like its 2019.

Does anyone know why old aeroplanes used the plastic tube style of headphones, instead of copper wired? From the blog post, it makes very good sense why the MRI headphones are necessary in that setting. Edit: From this URL: https://avidproducts.com/2023/12/08/celebrating-70-years-of-... This type of headphones are called pneumatic headphones.

Spitballing: Cost: one speaker and tubes was probably cheaper than 200. Weight: old headphones were chunky, see above. Comfort: not wearing giant chunky headphones you weren't accustomed to might have been preferable Breakability: pneumatic headphones were harder to break, cheaper to replace Stealability: passengers would have no reason to steal the headphones, and if they did it was cheap to replace. All of these go…

> Cost: one speaker and tubes was probably cheaper than 200.

I'm pretty sure there were 2 speakers in each arm rest. I think it's more about them being harder to break and cheaper to replace. When I flew on an airline that used them, they came clean in a sealed bag. They may have been brand new, or at least cleaned and sterilised. Electronic headphones are unlikely to be as cleanable.

Yes— there was a time where the free headphones were this style and you could bring your own electrically conductive headphones (with the right adapter, since it had separate RTS jacks for left and right channels) to enjoy a slightly better and louder sound quality

When I was a kid, I once brought a stethoscope with me on the airplane so that I could watch the movie for free. (Or rather listen to it.) I pulled off the heart-listening cup part of the stethoscope and inserted beverage straws into the rubber tubing. Then I put one straw into each of the two little holes in the armrest. It worked perfectly! Until a stewardess caught me and made me stop.

Thus sparking the engineer’s natural distrust of authority figures.

Lol, since we're going down this road... my clothing ends up getting stored more as a cache with an LRU policy. Every 6 months or so the items at the bottom of the drawer get assessed for eviction (donation). My favourite items are always on top, less used items are easy to find, and the unused items are easy to identify.

This is a much more efficient approach than Maria Kondo’s suggestion to hold each item up and determine its joy factor. Do you not procure multiple copies of items that have a high value assessment?

I mean… I’ve got a bunch of fungible black t-shirts from Costco if that counts. They fit reasonably well.

There are a bunch of more expensive unique items too. I do actually find it a bit interesting to see which ones float to the top and which ones don’t.

Funny you mention Marie Kondo though. I do roll my clothes instead of folding them before putting them away into the cubes. I don’t entirely get it but it seems more space efficient that way.
