Noise-Cancelling Headphones

Noise-cancelling headphones have now come down to affordable prices of about $50 (also available for $300 or more). These really help - as I found out with a $69 Maxell pair on a 15-hour Australia flight. They cancel out especially the low frequency noise such as the engine and part of air conditioning and allow for great sound quality when watching movies. Other brands are Aiwa, Sony or BOSE. They can also be effectively used at home while mowing a lawn or vacuum cleaning. The effect is quite amazing. Highly recommended for people who travel a lot.
