does ipad 10th generation have a headphone jack

The iPad 10 does not have a built-in 3.5mm headphone jack. If you wish to use conventional wired-headphones, you will require an Apple (or equivalent) USB-C to 3.5mm Headphone Jack Adapter:

• Apple Lightning to 3.5mm Headphone Jack Adapter

Some compatible third-party USB-C hubs also include a 3.5mm Headphone Jack.

Some users may choose to use a dedicated third-party DAC to connect their high-quality analogue headphone to the digital USB-C port of the iPad. Here are some examples:

Instead of a wired headphone (either digital or analogue), many now users prefer wireless Bluetooth headphones or earbuds. Again, there are many to choose from - including Apple’s AirPods, AirPods Pro and AirProds Max.
