USB-C: Everything you need to know(4)
Jul 26, 2018

It could mean the end of the headphone jack

‘Intel wants to kill the headphone jack,’ read a TrustedReviews 

The story concerned PC giant Intel’s efforts to encourage the inews headline from April 27.ndustry to abandon the trusty old 3.5mm connector we all use for our headphones. You’ve probably guessed what the suggested replacement would be. Yep, USB Type-C.

You might wonder what the problem is with the 3.5mm standard, and where it falls short of USB-C. In truth there are several issues.

For one thing, headphones jacks are bulky. Apple famously ditched the headphone jack in the iPhone 7, because it has long been seen as a key component that’s holding phones back from getting even thinner. USB-C, by contrast, is helpfully flat.


More importantly, the 3.5mm standard is one of the last remaining analogue connection standards still in use today. It dates back to the 1960s, and it’s only useful for doing one thing: transmitting sound. Even then, technology needs to be implemented to deal with the inevitable interference that accompanies it.

Not only is USB-C a digital connection, ensuring a base level of sound quality, but it can multitask too. So, for example, a pair of USB-C headphones could play high quality music whilst simultaneously measuring your heart rate and feeding that information back to your phone.
