The Audio-Technica ATH-M50x headphones are some of the best cans you can get without spending hundreds of dollars, and they go on sale fairly often. Today, you can get a refurbished pair for a mere $90. Some may scoff at paying $90 for headphones. Your phone came with earbuds, right? So why buy something else? Because these are way, way better.
The non-refurb M50x headphones have over 2500 reviews on Amazon with an average rating of 4.6 stars. So, they're pretty well liked. You'd usually pay well over $100 for those, but the refurbs are still very well-reviewed. You get a 90-day warranty as well. The M50x headphones are praised for being comfortable with excellent sound performance for the money.
The listing is sold by Woot, but fulfilled by Amazon so you get Prime shipping. Since this is a gold box deal, you can only get the sale price today. Also be aware it's only the black model that's on sale. The white M50x headphones are still around $120.
