Before anything else, you'll want to figure out how much you're willing to spend on new budget earbuds.

It's key that the earbuds you buy fit your ears well. They should offer a comfortable, secure fit. If you don't get a tight seal with noise-isolating earbuds, sound quality and noise canceling can be dramatically impacted for the worse.

While we don't expect as much from cheap earbuds, you still hope they fit well and sound decent. That's why it's critical to buy your buds at a retailer that has a good return policy, in case the buds just aren't good enough.
