Amazon currently has Samsung's Level On PRO Wireless Noise Cancelling Headphones available for just $149. That's actually good for $50 off of its regular price. That makes this a prime time to pick up a pair of wireless headphones - especially with most smartphones ditching that headphone jack.
These headphones from Samsung are noise cancelling, so they are going to be great for taking on a trip, as you can drown out the noise around you, which is great. These also have some pretty big drivers inside, allowing for great, full sound out of these headphones. Samsung says that these can last around 10 hours of continuous playback or 200 hours of standby. Samsung does include a 3.5mm cable, so you can use these as a wired pair of headphones if you prefer.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap next-day shipping if you need it here extra fast.
