I dont inderstand how they are such different quality from the ones I had since they are the same brand! I bought this for my hiking boots which had a not-so-nice smell. I loved this product at first, the extra pockets super convenient and keep things organized. After I emptied the bag when I had reached my destination, the bag literally still looked brand new! Fit is good but the opening is snug and they need a firm pull to put them on, but that helps keep then securely on your feet. Used on daily basis for inhouse. But other than that, they are still great headphones. This also helps solidify the unit. I only needed to pump a little air into my bike tire to firm it up and it literally deflated all air from the tire so that it was FLAT. Wenn man am linken Ohrhörer 2x tippt bekommt man den Sprach Assistenten (Google - Siri - Alexa).
