- anc -- the same/close/not impacted much-comfort-- needs beak inThey feel better than the original after break in, to me it didnt start that way. Arrived a couple days late but it’s okay, for really nicely love them Customizable control feature could be very enjoyable for using experience. I had a tiny issue breaking them in, but thats to be expected with a brand new pair of sandals, especially given I was walking a lot in them right out of the proverbial gate--it was just a very minor rub on the top of my foot. sooo comfortable They feel like slippers. If you want these for walking and general all day use you got a winner but for running I would look else where. - Comfortable- Light weight with low friction- DPI increments of 25 (vs Steelseries 100). It is a noticeable difference with my old headphones; although I dont think the old ones were specifically noise blocking, they did muffle noise while these AKGs do not. I’m not saying that it won’t give you discomfort if you wear it that long for 10 days but it is worth the price and earned it’s keep for sure.
