It constantly goes off, sometimes when the device is next to my phone. Ride Safe! so just wasted my money 😟. It is that kind of plastic. Took a few days to break it in, but is a great fit and very helpful. I have to return one and dared to buy another even I love the style and the quality. My rack specifically was not brand new and has been opened. A great for bass lovers but for those who dont like punchy bass, you should not go with these. The cable is really good for its price. The grips themselves do the job.
