Usually, a pair of budget headphones or earbuds comes with an obvious trade-off: they might sound great but struggle to connect to your device consistently, or have sub-par ANC.

When I tested the EarFun Air Pro 4 earbuds for our best noise-cancelling headphones guide, I struggled to find that trade off. Their excellent battery life, noise-cancellation, sound quality, and customization made them feel much more expensive than $89.99. And as of March 17, with Amazon offering an on-page coupon for the black EarFun Air Pro 4 earbuds, their price feels even more impressive on sale at $65.99.

Admittedly, part of what I liked about these earbuds during testing is that they do go on sale relatively often, so if you can't pick them up now, I imagine we'll see this deal again — and if you can, it's a great time to grab them.

Along with the earbuds, you'll get access to the companion app, which allows you to customize the touch control settings, use the custom EQ tool (making earbuds that sound great out of the box even more suited to your audio taste), and adjust the different ANC modes — a feature which I've not seen on headphones twice the Pro 4's price. They also connected to two devices, and switched between them, without issue.

Battery-life wise, EarFun claims about 7.5 hours per charge with ANC and 11 without, with 27.5 hours and 41 hours in the case which each of those respective modes. Thanks to the light indicators on both the inside and outside of the case showing the relative battery life of the buds and case, I never felt caught off guard by a low battery indicator.

So what's the catch? Well, the case is plastic and is perhaps where the earbuds most obviously show their price. Performance-wise, their touch controls are sensitive, and not great at distinguishing between a one, two, or three press motion, making it easy to adjust the wrong setting altogether. For that reason, I toggled them off, and although not convenient, this didn't detract from the experience enough to outweigh all of these earbuds' pros.
