|Audio-Technica ATH-ANC7B QuietPoint Active Noise-Cancelling Closed-Back Headphones, Wired||
Great cost to performance noise cancelling by far!!!
|Sennheiser PXC 250 II Collapsible Noise-Canceling Headphones||
$60 for Sennheiser's!!! Great value with pretty good noise cancelling for the $$$
|Sony MDRNC60 Over-the-Head Headphone||
Better noise cancelling than the Audio-Technica's but worse sound quality
|Bose QuietComfort 15 Acoustic Noise Cancelling Headphones (Discontinued by Manufacturer)||
Not cheap, but price drop by $40 due to the new QC25s. I use these QC15s everyday and love them
