Sennheiser PXC 350 NoiseGard noise-cancelling headphones

It is really interesting that there is not a clear choice in the mid-range ($150-$200) when it comes to noise-cancelling headphones. The Bose are said to be the best, but most people don’t want to pay for them. At $330, The Sennheiser PXC 350 is priced comparatively to the Bose QuietComfort 3 and I can only trust Sennheiser to have made it at least as good or better, but I really don’t know. The Sennheiser PXC 350 comes in black or silver. Compare prices
