To S. Andrea Sundaram,

I hope you have a few minutes to answer a quick question, or at least guide me in the right direction. I'm in the market for a new set of noise-canceling headphones as my last set were stolen recently -- and with another 13-hour flight coming up, I need to make a decision soon.

I really like the reviews I've read of the PSB M4U 2s as well as a few others (Polk UltraFocus 8000s). I've had a few sets in the past (Sonys and a reasonable set of Pioneers), which have been in the $100 range. All these more expensive headphones are $350-$400. How much better are they likely to be going from $100 to $400? I'm not going to get a chance to try them out unfortunately.

It seems to me (at least I'm hoping) that the difference will be vast and (probably) either the PSB or Polk would amaze. Is that a fair statement?

Thanks,
Pete McFetridge

I have not yet had the opportunity to hear the Polks, but that may happen in the near future. As for the PSBs, you should expect a huge leap in sonic performance from the $100 noise-canceling headphones that you've been using. They will probably also offer better isolation -- although some less expensive models do perform very well at that task. While I can't be sure that the PSB M4U 2s will amaze you, I have no doubt that their performance will impress you. . . . S. Andrea Sundaram
