I come from a long line of studio headphones Sennheiser Sony ect..The quality on these to me are premium.Soft foam on the head, and ears a tiny bit loose but that's if you bounce around, I've worn them working out and drowned out my vacuum with noise canceling. The app is a must, and transparency mode is awesome but if you wanna drown out that annoying person the the transit or gym THESE are for you. And for the price you can't go wrong. 40 hours of battery life? Dear me great way to get fired from work rocking out to slayer for that long! Bye nancy, you sucked to work for anyway. \m/
