Steve Wozniak may have left Apple in 1985 but that hasn’t stopped the company’s co-founder from giving his two cents about the latest releases.

Like a worried yet slightly distant father, Wozniak just wants Apple to know that even if he can’t be there for it, he cares and wants to help it avoid messing up.

So true to form, he’s waded in on Apple’s decision to drop the headphone jack _– though it’s not actually been announced yet but is strongly rumoured. Wozniak is concerned by the idea that iPhone users would have to use either Lightning cable headphones or Bluetooth ones.

“If it’s missing the 3.5mm earphone jack, that’s going to tick off a lot of people,” he told the Australian Financial Review. “I would not use Bluetooth … I don’t like wireless. I have cars where you can plug in the music, or go through Bluetooth, and Bluetooth just sounds so flat for the same music.”

“Mine have custom ear implants, they fit in so comfortably, I can sleep on them and everything. And they only come out with one kind of jack, so I’ll have to go through the adaptor,” he said.

“If there’s a Bluetooth 2 that has higher bandwidth and better quality, that sounds like real music, I would use it. But we’ll see. Apple is good at moving towards the future, and I like to follow that.”

Previously, Wozniak has laid in to Apple over the company’s Watch, writing on Reddit that “I love my Apple Watch, but - it’s taken us into a jewellery market where you’re going to buy a watch between $500 or $1,100 based on how important you think you are as a person. The only difference is the band in all those watches. Twenty watches from $500 to $1,100. The band’s the only difference? Well this isn’t the company that Apple was originally, or the company that really changed the world a lot.”

In April, he expressed his concern over Apple’s low tax bill. “I don’t like the idea that Apple might be unfair – not paying taxes the way I do as a person. I do a lot of work, I do a lot of travel and I pay over 50% of anything I make in taxes and I believe that’s part of life and you should do it.”

After leaving Apple in 1985, Wozniak went on to develop the first programmable universal remote control, teach computer classes in an elementary school, build an early consumer GPS device, and launch a comic convention in Silicon Valley with former Marvel Comics boss Stan Lee.
