A:AnswerHello-
You can expect superior comfort and sound quality versus anything within the same price as the HD 238. The warranty, 2 years, is also first rate.
A:AnswerThey do not. No on ear headphones really will...if you want noise canceling, definitely look into In-Ear headphones...other than that, the noise canceling feature is a gimmick on On-Ear headphones in my opinion.
