I purchased this product primarily for use in in-flight TV/audio systems while traveling. I am very satisfied. Signal to noise ratio was substantially improved. Airplane (low frequency) noise reduction was clearly evident (subjectively about 50%)even when the signal volume was turned off.
Compact and easy to use if you don't want in-the ear. Sound cancellation works well enough, not as well as sound-isolating phones. OK for commuting, don't use these for audiophile listening.
Abysmal sound abatement. All it did was amplify the music rather than reduce ambient noise. DO NOT BUY.
