Noise-cancelling headphones are popular. Groombridge says they reduce the sounds around you so they do not need to be turned up to get over the noise of traffic, a plane or a busy office.
At home, wireless headphones are a must.
All of this doesn't come cheap. My 10-year-old son is delighted with the $18 set of noise-cancelling headphones he bought at Kmart last weekend but real aficionados can spend more than $1,000 on a set.
Electrical stores such as Harvey Norman, Dick Smith and Noel Leeming each sell dozens of models at prices ranging from $7.99 to $649.
Even The Warehouse has a range, from entry-level headphones to highly sought-after models such as Beats by Dr Dre High Performance Professional.
For top-of-range headphones such as Sennheiser, Beyerdynamic and Denon it's often necessary to go to specialist stores such as AV World and The Listening Post.
It's a good idea to use price comparison websites such as PriceSpy.co.nz and PriceMe.co.nz.
