My husband installed this in no time at all. Great sound quality, volume control, and comfort They fit perfect for me and are super comfortable. I would not recommend if you are half sizes like me and so the next size up is too big. The third one lasted for 5 months. Most people know how much a Harley shakes at idle. - not that isolating, should be fine for commutes but you will likely hear quiet background noise- might have to buy hard case, soft case included is nice but not very protective- call quality is okay, decent for phone calls- audible hiss on quiet tracks Does not seem like it would scratch the bicycle because the ends are rubber coated. I tried to return it before leaving on a trip, but the delivery window closed while I was gone (I know that part isnt their fault, Im just saying that I couldnt fix the issue so Im just out the money). The oil type wash is really odd at first but it washes off with water perfectly.
