Apple is no longer providing a 3.5 headphone jack in the latest generation iPads, with the latest one being the tenth-generation iPad.
The ninth-generation iPad, which Apple still has in stock, is the only iPad with a 3.5 headphone jack.
If you still don’t want to abandon your wired headphone, you can get an Apple or any other company’s USB-C to 3.5mm jack dongle to use with the tenth-generation iPad.
After slowly shifting the headphone jack from left to right, Apple has finally stopped installing one on their tablets. And after the tech giant discontinues the ninth-generation iPad, it would be the end of headphone jacks, and the Mac hardware will only be the one with it.
