AKG has introduced two new noise-canceling headphones, the $349.95 K 495 NC and $249.95 K 490 NC.
Bose says Beats' Studio and Studio Wireless headphones, soon to be owned by Apple, copy five of its patents.
They're refurbished, but also backed by a one-year warranty. You'd pay at least $100 for them elsewhere.
Despite some downsides, including a high price tag, the Bose QuietComfort 20 offers the best noise cancellation in an in-ear headphone and should tempt frequent travelers looking for a more compact alternative to full-size noise-canceling headphones, such as the Bose QuietComfort 15.
This popular pair of cans lists for twice the price. It features inline controls and can fold up to ride inside the included carrying case.

The QuietComfort 25 model takes Bose's already stellar noise-canceling headphones and levels them up to new heights.
