Sound quality is very good, no distortion, very loud at the same input level, I find myself running these at least 3 clicks down on volume vs my other headphones on an iPhone. The rest is trash. I like the fit and grip of the tread. This change increases clarity at lower volumes but can make the highs harsher with louder listening. Stuff that takes up little space. Ordered this headphone for myselfI mainly drive for my work and i am so much in ease after ordering this. I’m definitely pleased with my purchase, and especially pleased with the price since times are so uncertain. There is so much open airiness to these and again the layering and separation, dreamlike. So I love the style of these shoes. Bose is decent but you look stupid wearing them and B&O looks the best but the sound quality is worse then 20 year old walkman headphones.
