The Clear Harmony NC1100B is Able Planet's highest-end model headphone. It uses the award-winning Linx Audio Technology to improve sound quality and speech clarity. The package comes with a 1/4-inch airplane adapter to enjoy a wider range of audio devices and in-flight multimedia systems, good for frequent fliers. Also, the earcups fold for easy carrying. To enjoy maximum audio entertainment, you will need two AAA batteries to enable the ANC (active noise canceling). Otherwise, it works like a regular headphone. CNet compared these headphones to Bose's highest-end model
. Based on the review, the NC1100B used a thicker, firmer ear cushion, and may be a better fit for some. The primary shortcoming noted was an overemphasized bass. But overall, they gave the headphones a "good" rating, and for this price, you can probably mentally bump that rating up at least a half star for value.
