Released in last five years: 303 with IPx8 certification, out of which 122 also have a headphone jack.
So out of every three waterproof models, two don't have a headphone jack. Seems to support my rule of thumb.
- skyyler 4y agoYour rule of thumb is wrong a third of the time which is a D grade. Technically passing, I suppose.
- input_sh 4y agoYes, that's what rule of thumb means. It doesn't imply it's always the case, just more often than not. >60% is more often than not.
- skyyler 4y agoI think you're a bit off on what rule of thumb means. Something that's false 1 out of 3 times is not "generally true". If it was a 51/49 split in probability would you still call it a rule of thumb?
