Update (3/7/2017 7:00 am ET): This deal is no longer available.
Many frequent flyers, myself included, swear by their Bose noise cancelling headphones. They have decent audio quality, are comfortable to wear, and Bose’s noise cancelling technology really is market-leading. They can be a bit pricey, but here is a quick deal: Amazon is having the QuietComfort 25 on sale for $179.99 with free shipping.
This is a pretty incredible deal, since the headphones usually go for $299. Do note that only the white color is eligible for this price, and the headphones are sold by Bose through Amazon, so you will get free shipping, but not Amazon Prime.
These headphones are not the absolute latest version, since Bose introduced new, wireless versions a while back. However, I personally still prefer the wired version, since the in-ear QC20 allows me to plug into the in-flight entertainment systems of most planes. But if you fancy something without wires, you can feel free to check out the Bose QuietControl 30 (in-ear) or the QuietComfort 35.
