I saw a video where someone posted about this products quality and his experience with this headset. fits perfect and my 8 year old says its comfy. it is cool that they can be charged on the go in the charging box. This product replaced my old front wheel riser which had only a single height and was very small, often sliding around when I used my road bike on an indoor magnetic trainer. Have to say that I probably could have gotten away with the 5/6. I was just going to use these as work headphones for classes, but now I use them all the time. This is really a matter of personal preference and your usage. They are also far more comfortable than Adidas that are not Ultraboost. These are not just slippers; they are a way of life. yes if you run across the snow in dead of night you’ll soon be three inches taller, elevated on “clog made “ snowballs.
