I test headphones for a living, and these are the best Sony Black Friday deals I've seen so far — up to $500 off soundbars, headphones and more

The WF-C710N rank among our favorite buds of all time. Their ANC outperforms more expensive rivals, and the sound is wonderful. They've got 30 hours of battery life, along with a nice transparent blue colorway. Good enough to eat. (Please don't eat them, they're not actually Jolly Ranchers).

These tiny buds have soft silicone fitting wings to make them more secure. They sound really good too, and feature solid ANC to keep the noise out. The case is a bit thick, but it provides 22 hours of battery life.

The WH-1000XM4 are a slightly older pair of headphones, but they still pack a punch. They're comfortable, filled with features, and they sound good to boot. This is their lowest price ever.
