Bose says Beats' Studio and Studio Wireless headphones, soon to be owned by Apple, copy five of its patents.
While they may not be quite as comfortable as Bose's ultrapopular QC 15 headphones, the Harman Kardon NCs offer slightly better sound and have a built-in rechargeable battery to power the active noise-cancellation circuitry.
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.
With the freshly redesigned QC25 ($299.95), Bose has not only enhanced the sound and noise reduction of its flagship NC headpone, but made other small design improvements.
Monoprice's Noise Canceling Headphones are about 70 percent as good as the Bose QC15s for a little more than a third of the price.
Bose filed suit against Beats in July, accusing the rival headphone and speaker maker of infringing five patents related to noise-canceling headphones.
Despite some downsides, including a high price tag, the Bose QuietComfort 20 offers the best noise-cancelling in an in-ear headphone.
If you can't afford Bose's QuietComfort noise-canceling headphones, the attractively designed and more affordable Sony MDR-NC200Ds are worth your consideration.
AKG has introduced two new noise-canceling headphones, the $349.95 K 495 NC and $249.95 K 490 NC.
