Noise-canceling headphones are a must to listen to the entertainment system on the aircraft or even your own tunes. Some people pack bulky Bose but I have found the Sennheisers to be perfect - lightweight, small, have a travel pack to keep them in plus a set of adapters for the various airlines. The single AAA battery lasts around 40 hours of flight listening time.
I want Sennheiser In-Ear Noise Cancelling Headphones (MX 375) - Black because listening to lectures and to my music without disturbing those nearby is needed. #SetMeUpBBY
TOP of our list of business traveller essentials is a good pair of noise-cancelling headphones, which will help you to work or sleep through crying babies and loud plane engines. This pair from Sennheiser are tiny, but boast up to 20dB noise attenuation. And their robust cabling and casing means they’ll survive being stuffed in your pocket or travel bag.
