Some travel items are just indispensable when it comes to travelling and are a true travel essential. To me a travel essential par excellence is an over ear noise cancelling headphone. Absolutely indispensable in an airplane. Especially when you have (young) children seated close to you.
For the past few years I have never travelled without my noise cancelling headphones, and it’s the first thing that comes out of my backpack as soon as I have found my seat. Definitely a must when putting my travel gear list together.
