At the top of volume level 2, I could hear people in the same volume as wearing no protection at all, while wearing both 32NRR ear pugs and the 100s. Although I purchased the correct size for my feet, the opening to get your foot in is quite TIGHT. I hope. This means that you have to work on the bike being mindful of a protruding leg beneath. Great for hanging clothes to dry or to use for clothes that have been ironed. The headphones abruptly stopped working altogether after three months and because I had a warranty I filled out 25 mins of paper work and sent in receipt copies and when I was done I was told the manufacturer had me still under warranty and they cannot honor it, afterwards I found out that the warranty through Sennheiser is only good if you buy DIRECTLY through the company. It?s so nice that these fit INSIDE your ear so, unlike my AirPods, there?s nothing hanging down. I have received the S20 but not 5G, am really unhappy ?? I jerked my head around and the right earbud popped out and landed in the dishwater. all sorts of things.
