| Bottom line | Info unavailable | The PSB Speakers M4U 2 Active Noise Cancelling Headphones combine above-average noise cancellation with excellent sound quality that's well worth the price for dedicated audiophiles looking to eliminate ambient noise. | 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. | While they're no bargain, the Bose QuietComfort 15s currently offer the best sound and silencing capabilities in a pair of noise-canceling headphones. | The Audio-Technica ATH-M50 Professional Studio Monitor Headphones are among the best available for less than $200, offering excellent sound and build quality. |
