In this episode, aerospace engineer Hossein Seif Zadeh (a.k.a. hossein_au on the Australian Frequent Flyer forum) explains how noise-cancelling headphone technology works and the difference between a $100 and a $600 pair of headphones. A lot more science goes into creating the perfect pair of noise-cancelling headphones than you may realise!

Also in this episode, found out how Australians may be able to benefit from the great deals available on U.S. credit cards, and how to easily earn Star Alliance Gold status via the Asiana Club frequent flyer program.

And as always, we take a look at the biggest Australian airline & frequent flyer news from the past fortnight, including Qantas’ brutal COVID-19 recovery plan and Virgin Australia finding a new owner.
