People seem to think that the headphone jack is only used in iPhones and smartphones. It's not going anywhere - even if all the smartphones get rid of it. Most people seem to forget that it's still used extensively in other audio applications. I bet your desktop computer speakers are using that jack. I bet your desktop speakers don't have a lightning or USB-C input port for audio - and there is no other standard to replace that type of application. Optical cables aren't replacing them - they are meant to provide digital audio and usually in lieu of RCA jacks. So, I really wish people would stop saying that it has to die just because Apple says so, because maybe if you are in an Apple bubble, you really might think the 1/8" jack is only used for smartphone headphones.
