Silence is golden? It could well be if you invest in one of these noise cancelling headphone sets. We have three sets of headphones from Sennheiser, Sony and Acoustic Authority. Which will prove the best value?
"If you haven't guessed already, our ultimate recommendation goes to the Sennheiser PXC 250s. However, it has not escaped our attention that these are the most expensive headphones on test here today, and are possibly beyond the justifiable range for a lot of people. The ultimate question whether they are worth spending an extra £25 on over the Sonys? If you have the cash, then we'd say definitely."
