I'm super curious… a. What in these files triggers the explosion of noise (and whether other people have run into this or the author would mind sharing a representative problem file). b. Whether an output attenuator (or "resistor") would work to quiet the noise (edit: the hiss, not the explosion) without a powered circuit.

I don't have this issue on my Android phone (G5+) but I did have a very similar issue on my laptop (XPS 9350) where there was lots of line noise whenever the power management turned off the audio chipset.

So I wonder if it's something with this specific phone?

Interesting point buried in here: since Android is open source, you could go in and fix the bug, but then because you're not running an official Android version you'd lose access to the Play Store and other services. Something's not really free if there's a penalty for doing it. Since freedom to run a modified version of software yourself is one of the four freedoms of free software, this highlights the difference be…

> I'm not saying open source is bad and everyone should prefer free software.

Why not?

A dongle is ~10$ and you can pick one up anywhere. This horrible contraption he had to build just to enjoy music costs way more in time & money.

Makes me wonder if the guy wants (subconsciously or not) to have more problems with technology he’s using just to have an opportunity to tinker with it to make it better. Certainly seems like the type. Not necessarily a bad thing, though, but in such case he might as well drop the complaining tone.

I see this a lot with Linux and non-stock-Android users.

I'm not sure why Apple is receiving any sort of praise here. I was constantly assaulted by an "explosion of noise" glitch when working with Logic Pro in OS X. I could have the system volume level set to the lowest possible setting (25% of 1 notch), and yet I'd still occasionally get deafening explosions of noise as if I had the system volume set to the full 16 notches. The explosion is just short enough that there's zero chance of you having any hope of ripping your headphones off as quickly as possible to spare your hearing. No, by the time you hear the explosion, it's already too late. I did in fact start losing my hearing from this and completely gave up on making music.

It (the dongle) is still wholly unnecessary.

Are Bluetooth headsets still much behind wired ones in terms of sound quality?

As an owner of Bose QC35... yes. The headphones themselves sound pretty good. But when playing over bluetooth sometimes compression artefacts are audible. The artefacts are caused by the bluetooth protocol for stereo audio itself, so you're going to hear them even if you play FLAC files. Also latency is pretty horrible. 200 ms+, enough to be obvious.

Bose QC35 are, I think, AAC and SBC only, so this is to be expected.

Most modern laptops have more than decent audio output, but if more quality is needed one could buy a small external sound card for a lot less than €100. This one for example would fit easily in a notebook bag. https://www.thomann.de/gb/miditech_audiolink_light.htm About the article circuit, I 'm not that sure the 5532 is a good part for headphone amps, unless the phones have a high impedance and resistance: they're…

Regarding the op amp selection, he just used them because he had them lying around.

  "If you wanted best possible sound you'd use some actual audio op-amps rather than these cheap NE5532P. And buffer the output of the op-amps somehow. But of-course size and cost balloons if you start adding buffers and stuff."
What I like about his project how he simply used a couple magnets to hold the lid on. Microsoft did something similar on my keyboard, but I don't know that it is something used much on DIY projects like this.

> APPLE IS A SYMBOL OF PRETENTIOUSNESS AND IGNORANCE - YOU DO NOT EVEN KNOW HOW YOUR PHONE WORKS Is this guy for real? I don’t know the nitty gritty of how most of the things I use work, I’m only concerned that they work. Sounds like sour grapes.

I’m only concerned that they work.

Which, as you allude to, is not guaranteed no matter what it says on the tin. Samsung is my go-to for that point. Not that features were half-assed, or kinda worked. No, having an icon on a screen does not count when what backs that icon doesn’t even pretend to do what it says. (To be specific, their fitness stuff was literally laughable in how broken or, lets be honest, how unimplemented it was.)

I think what gets missed is that the “Apple tax” (the “M$” for the 2000s, indicating the writer is to be ignored) is actually the “not a broken POS, and does what you thought it would do” convenience fee. Oh, sure, there’s Pixel and the like if you don’t like Apple. Last I looked, you’ll still pay the “Apple tax” even if it goes to Google.

And I swear, the next neckbeard ranting about how people don’t how their tech works either better take public transit to work, be ready to rattle off the Otto cycle used by their ICE car, or STFU.
