Good purchase 10/10 I wonder if theyll work on my walkman

^

i bought them off amazon with prime because i want them before march

Fellas

I added 3 buttons to my fuckinnnnn

My kz zsns

Look at that quality solder work

mmmmmmm

3 separate 300ohm resistors just to make the required 450ohm

I spliced it in the mic

No wires were cut

I guess this means ive got 4 buttons on it

Just 2 of them do the same thing

Anyway I can flip the pages of my Chinese cartoons easier now

Goal achieved

Ikr

Anyway, it works

And there aren't any cold solder joints

So it's all *technically* correct

I'm especially proud of the really tiny smd resistor

The small black dot between the 2 solder blobs there

I wish zsns came with 3 buttons

Single button headphones suck

And my solution isn't exactly the most elegant thing in the world

Why did I not find this before. I could've avoided using 3 resistors

For 450ohm

It *is* android documentation

There's multiple pages

This is what I was going off of earlier

Mostly price probably

Ss caps are like a few cents more expensive probably

Basically if you put a certain resistance on your mic line android detects it as a button press

If you short mic to ground it's play/pause

240ohm is volume up I think

Yep

No just resistance

?

Yeah basically

And a microphone too

iOS does it differently though, they use some signaling idk

But for android, just short the mic pin to ground with different resistances

It's not really too important to knoe

Most people aren't diying inline buttons on their headphones

Android detects normal TRS headphones by detecting a dead short across mic and ground when you plug them in

3 pin

Or whatever

Well you can't if the plug is TRS

You need your headphones to have a TRRS plug

Yeah

Trrs is normally laid out as l, r, ground, mic

I think

There are multiple standards

Ground isnt the last one

Most mobile devices now use ctia because that's what apple uses

Yep

But everyone copied them

It's not balanced

It's not really too retarded

Everyone adopted the apple standard

Since the only thing to use omtp before were those 2.5mm headsets for old flip phones and things

trrs on 3.5mm wasnt common until apple started using it, and then everyone just adopted their standard to be compatible

None of this is balanced audio.

Also, with enough rings, yes

You'd need something like TRRRRS though for stereo balanced audio,ground, and mic

Which doesn't exist

There exists TRRRS

Only Sony used it

For some weird ass noise cancelling headphones

Basically they shoved mics into the earbuds and had to pass that to a phone to have the phone handle noise cancelling

Because nobody gives a shit about it

I play 128kbps mp3s on my chink phone's built in DAC

Balanced audio isnt going to help

No

Not necesssrily

Gimme one second

Boom

No 3.5mm jacks

Just put tapes into the headphones

Theres also headphones with built in radios

With no jack

Its a micro cassette player

Minidisc exists

And uhhhh

That other format

Whatsit

Techmoan did a video on it

Oh and UMD

No not 8 track those were massive

And not super8 that was for video

dataplay

That was it

The dataplay discs

My favourite format is still DAT

DAT is so cool
