I tend to use passive headphones with 3.5mm jack, they have no electronics in them except the small speakers. They do not collect data. They are also used by musicians when doing audio mixing so its should sounds neutral and good. That the headphones does not have electronics and batteries means they will last longer and thus be be better for the environment.

All my MDR-7506s needed after 3 years was new ear pads.

I only installed the Bose app when I was going to be on a plane, as the app allows you to pair multiple Bose headphones to one source. Then you can watch the same movie with someone else. Edit: Bose also had a nice big opt-out button in the app, and asks during setup.

With the app you can also change the cancellation level, they’re pretty isolated even with the feature powered off entirely but it helps out in some situations.

My Boses allow you to set the cancellation level with a button press. It cycles through three options: high, low, and off. Does the app enable more fine-grained control or something? Perhaps per-ear cancellation settings?

I (and many other engineers I know) do this too, and for a good reason. It's a simple system. Same reason I don't use WiFi at home but ethernet: it's simple.

> It's a simple system

Even though I get your point and I am convinced you're using "simple" aptly, I will nitpick the obvious: passive headphones can be deceptively simple or a marvel of engineering.

If you didn't get the chance to listen to some music through proper audiophile headphones, I do recommend to spend some time at the closest audio retailer and live the experience.

Everyone, including headphone manufacturers, are trying to get in on the gold rush that is turning their customers into fonts of personal data that can be sold to the highest bidder.

I see this sentiment mentioned a lot, but who actually pays for this data? Is there a company I can call that will buy my amorphous "user data"? What are their names?

Just because you haven’t heard of them doesn’t mean they don’t exist.

Ask yourself (as the article does): why would they even need this data? (menstrual cycle?? Really!?!)

Can a phone reasonably drive such high-impedance headphones anyway?

As one data point, the headphone jack-having iPhone would drive 26.39 mW into 33 ohms, which means that at max volume you'd be damaging your ears at a volume of around 100dB with the 300ohm impedance and 105dB/mW SPL. So yes, the previous poster could conceivably be doing the thing that they said they were doing.

Their sensitivity is only 97dB/mW. But I think it's more complicated than that. The amplifier might be able to deliever 26mW into 33 ohms but can it deliver that into 300 ohms? It would have to be able to produce high enough voltages. Also the impedance goes up to almost 600 ohms at the resonant frequency of the headphones, requiring even more voltage [1]. You'd obviously get some sound and it would probably even be loud enough, but there would likely be a significant effect on the frequency response and possibly more distortion that you'd like.

> they will last longer and thus be be better for the environment This isn’t necessarily true. My wireless headphones have been with me for years. My wired earbuds are cheap enough that I can lose or damage them without care. The former are far better for the environment.

Of course it's not a universal rule. But apples-to-apples, with a wired vs. wireless set of similar construction, cost, and intended use, the wired will outlast the wireless, solely due to the battery (not to mention the other complexities inherent to a wireless set).

Well menstrual cicle is a gold mine. But I miss the connection with headphones...

My Sennheiser HD25 have been with me for 10 years and I stepped on them, dropped them used them outside in the rain, in sub zero degrees and three times a week while jogging.

10 years of that is a heavy thing to survive. In fact I know hardly any object that would have survived this long.

You have LAN ports in your bathroom?
