It seem to smoothly reduce the volume and different channels will drop before the other. The cord is heavy and durable. On the bike while on the stand it will slide of position. The lights on the toes are great! Just remember that you need a base to attach this to. but this ones did it. Definitely a must if working from home. I bought these shoes for a wedding Im in and I received them yesterday. Sturdy and was very easy to install. Für die Schuhe gibt es 5 Sterne, den Verkäufer möchte ich um einen entsprechenden Größenhinweis bitten.
