Sony has many different businesses under their umbrella, including an audio business that makes some of the best headphones and speakers available right now. The latest pair of headphones that the company announced was the MDR-1000X, which are Hi-Fi (or High Fidelity) headphones and are also Bluetooth. Which means you'll be able to use these headphones with devices that don't have a headphone jack, like the Moto Z. These are great headphones for those that are audiophiles, as they do produce some pretty incredible sound, and are still fairly lightweight. According to Sony, the battery on these will last you around 10 hours or so of continuous playback. So there's definitely enough for a full day and then some.
When Sony announced these headphones last year, they were priced at $399. Which was a pretty modest price for what you're getting here. They were seen at just $349 over the holiday season last year, and now eBay has them for just $319. That is effectively the lowest these have ever been. Now these are refurbished, unfortunately, but they do still come with a warranty, so you'll still be covered if something should happen to them. These do ship from within the US, so you'll get them sent to your door fairly quickly, depending on which shipping method you choose at checkout. It's currently unclear how long these will be priced at $319, but you'll want to grab them before they are gone.Buy the Sony MDR-1000X Bluetooth Hi-Fi Headphones
