Amazon has the Sony XB950N1 which are a pair of Extra Bass Wireless Noise Canceling headphones, on sale today. Bringing the price down to just $246.07. That's good for around $50 off of the regular price. Now it is listed as $248 on Amazon's site, but there is a coupon below that will take an additional $1.93 off of the price, so you'll need to clip that coupon.
This pair of headphones from Sony aren't that fancy, but they do the job quite well. These are well-padded headphones so that they are going to feel pretty comfortable, even if you do need to wear them for a few hours or even all day long. These are part of Sony's Extra Bass lineup which means that you are going to get some great sounding bass out of these headphones, the mids and highs won't be sacrificed either, as they will also be pretty good sounding. Since these are over-ear headphones, they are going to provide some great battery life here. And that is around 22 hours on a single charge. That is with noise cancellation turned on, but if you turn that off, you will be able to get around 30 hours of battery life out of these headphones on a single charge, which is pretty impressive to say the least.
