The Bottom Line While they're no bargain, the Bose QuietComfort 15s currently offer the best sound and silencing capabilities in a pair of noise-canceling headphones. If you can't afford Bose's QuietComfort noise-canceling headphones, the attractively designed and more affordable Sony MDR-NC200Ds are worth your consideration. The Audio-Technica ATH-M50 Professional Studio Monitor Headphones are among the best available for less than $200, offering excellent sound and build quality. 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.
