Performance is great and it is for the most part smooth and responsive. Great weather proof box. This product is by far the best I have tried. And they come in a 3 pack. 5Qualità Audio: 9Ottimo prodotto da parte di Sennheiser. Things I like1. It just that much larger then normal sizes. Sound quality is very good and environmental noise reduction is absolutely sufficient for the home-office, where other family members are talking in the background. It is easy to put on my RAV4 and I can easily carry mine & my friend?s bikes everywhere. My husband always sets out his clothes for work the night before and hangs them on our towel rack which drives me crazy the next day when there are still hangers that end up getting knocked off on the floor whenever we try to get towels down so I was looking for a solution for that and this is it!
