The ATH-ANC7 requires only a single AAA battery to power up to 40 hours of noise canceling. But this zombie still has more to offer as its audio can function even when without the noise-canceling function.
Recommended price: $1,580.
SENNHEISER PXC300
The latest in top-of-the line noise-cancellers, the lightweight PXC 300 is marketed as a “travel” gadget that drowns out noises when you’re on the go. Perfect for frequent flyers.
Recommended price: $1,368.
SONY MDR-NC60
Sony unveiled the NC60 earlier this year, which supposedly blocks out up to 85 percent of ambient noise. Its audio driver and external noise detector can be combined into one unit, creating a better
and more accurate feedback system.
Recommended price: $1,420.
BOSE QUIETCOMFORT 3
A significant step-up from its predecessor, the QC3 is smaller and uses rechargeable lithium-ion batteries slotted into the right ear cup. And thanks to the layer of "memory foam" covering the ear cushions, it is almost impossible for sound to leak out.
Recommended price: $3,480.
AKG K28NC
Smaller and lighter than most of the big guys, the K28 can be folded up to fit into your pocket. It has exceptional bass response and is equipped with an external noise filter and battery pack.
Recommended price: $2,780.
