The Sony WF-1000XM4 launched for US$279.99, but the premium earbuds can be picked up for as little as US$178 during this year's Black Friday deals. Available at a discounted price in either colour, the WF-1000XM4 supports the high-resolution LDAC codec and lasts up to 8 hours between charges, among other features.https://www.notebookcheck.net/Sony-WF-1000XM4-Substantial-savings-to-be-had-for-premium-earbuds-in-both-colours-during-Black-Friday-promotions.670447.0.html
