Apple co-founder Steve Wozniak is unimpressed by rumours the company plans to remove the headphone jack from the upcoming iPhone 7.
The removal would "tick off" a lot of customers, Mr Wozniak warned in an interview with the Australian Financial Review.
"I would not use Bluetooth … I don't like wireless," he said.
"I have cars where you can plug in the music, or go through Bluetooth, and Bluetooth just sounds so flat for the same music."
It's music to the ears of many Apple fans, who vowed to boycott the iPhone 7 if the traditional 3.5mm headphone jack was taken away.
The design of the iPhone 7 is just a rumour, with no official word on the look, release date, or even name of the next iteration of the phone.

It's speculated with the headphone jack removed, users will either have to buy expensive wireless earphones or buy an adapter to use their normal ones.
And Mr Wozniak would be one of them, unless Bluetooth quality steps up and can sound like "real music".
"[My earphones] have custom ear implants, they fit in so comfortably, I can sleep on them and everything," he said.
"And they only come out with one kind of jack, so I'll have to go through the adapter."
Mr Wozniak co-founded Apple Inc with Steve Jobs in 1976 and remains on its payroll as an advisor, despite leaving in 1985.
