Active noise cancellation

by on Oct.29, 2012, under Traveling

A great way to kill time on longhauls is to enjoy a good movie, TV show or by listening to music or an interesting podcast. A decent set of headphones will help you enjoy this and the latest trend here are headphones with noise cancelling technology. This works by having the headphones inverting the incoming sound waves so that they, when combined with the incoming sound waves, are cancelled (or at least reduced). This is explained in more detail here.

Noise cancellation makes the headphones more expensive, about twice as much, but don’t forget that they also can be used to cancel out background noise only. In oher words, they are of great use also when you want to sleep. Airlines have been lending noise cancelling headphones to business and first class passengers for years. Works great on buses and trains too. Time to get yours?

Stuff I look for when shopping for headphones:

  • Decent brand. For instance Sennheiser.
  • No cables, i.e. Bluetooth A2DP.
  • Foldable for easy storage.
  • Hardcase for better protection.
  • Active noise cancellation.
  • Talkthrough functionality.
  • Convenient charging: USB and/or replaceable standard size batteries.
  • Airline and 1/4″ adapters.

If you wear glasses you may want to go for an on-the-ear version rather than an over-the-ear.
