:) One is good but two is better. I need to be able to answer the phone and have the person on the other end actually hear me, unfortunately they could not on either pair.  Gerade beim Fahrradfahren keine schlechte Sache. My one disappointment was that you have to keep pressing the mute button for it to remain on mute.  Even at low volume on television the noise reduction was virtually non existent, sending them back.  (My forefoot either felt cramped or "sloppy" in previous shoes. Mistakenly bought. Unfortunately the river on one of the shelfs hinges arrived broken and therefore does not hang level.  I like the additional space over a 6 racquet bag. I was surprised that these are such high quality considering the  price.
