The Sony WH-1000XM5 are just about the finest pair of noise-cancelling headphones that money can buy, and right now you can snag a pair for even less. They're equipped with dual processors and eight built-in microphones for top-of-the-line noise-cancelling capabilities, and the Integrated Processor V1 provides optimized, crystal-clear audio. They also boast an impressive battery life of up to 30 hours, and they automatically pause your music when you remove the headphones or start speaking.
Note that this deal is on an open-box pair, which, according to Woot, means they have been tested and are in full working condition, but the box may be missing some peripherals like a charging cord or cleaning cloth. But if you can live with that, this a great chance to snag one of the best pairs of headphones on the market at a discount.
