Noise Cancellation is no Longer Limited to Bulky Headphones

Samsung released an earbud featuring active noise cancellation (ANC) that compares to the bigger/bulkier headphones. The earbuds are as small as typical earbuds with the exception of an electronics module near the audio jack. The key component in the electronic module is Cirrus Logics 47L51B. The CS45L51B processes information from the primary microphone plus 4 additional microphones (2 in each earbud) to provide a new level of audio quality from earbuds.
