I won’t travel without these Bose Ultra Headphones, and they just hit a new low price on Amazon Prime Day
If that's still higher than you'd prefer, then take a look at the more affordable Bose QuietComfort Headphones (the non-Ultra) version, which offer noise cancellation that's basically just as good and you can now get the Bose QC Headphones for just $199 (was $349) at Amazon.
