Buy If You Want a Headphone Jack
A lot of people still love using a pair of wired headphones. If you fall into that group, you might want to buy the Pixel 3a or Pixel 3a XL.
Google's Pixel 3 and Pixel 3 XL come with a premium design, but the design doesn't feature the popular 3.5mm headphone jack.
Thankfully, the Pixel 3a and Pixel 3a XL's plastic design does include a 3.5mm headphone jack. This makes their design a bit taller than the other Pixel 3 models, but you probably won't notice.
So if you love using wired headphone and/or don't want to spend additional money on dongles, you might want to buy a Pixel 3a.
