Amazon has discounted the very popular, Sony WH-1000X M2 wireless noise cancelling headphones, bringing the price down to $298. That is $50 off of its regular price, and does also bring them back down to their all-time lowest price. These have not been discounted all that often, so now is definitely the time to pick up a pair.
The Sony WH-1000X M2 are a great pair of headphones to pick up. Not only because they are wireless and noise cancelling, but they also provide some great audio quality. Allowing you to really enjoy your music while you're ignoring everything around you. These are capable of Hi-Res audio, which is great for audiophiles out there. Additionally there is ambient sound in the WH-1000X M2's here, which is going to be great for still hearing what's going on around you, but not drowning out the music hitting your ears. This is a good mode for using on a plane, so that you can hear the announcements and when flight attendants ask you questions. Finally, the Sony WH-1000X M2 come with some incredible battery life. These will last you around 20 hours of continuous playback. Of course, if you want to plug these in you can, and they'll last forever. With noise cancellation turned off, these will last around 30 hours on a single charge.
