There are two pair of small, medium and large tips. My expectations were limited. Im 57" and dont need the seat up very far. the noice cancellation made the music sound very clear and a joy to run in,they are nice and snug and didn?t fall out at all which I was not expecting,heard other brands were a little loose,there are different size ends to swap but for me the largest were the most snug without being uncomfortable. Though they are comfy and have a nice colour. Biggest draw back we noticed with this model are not comfortable as you use because your feet tend to skid inside as you wear and walk and push against front inner sole which is very frustrating. I picked up 4 each of the 71083 large and the mini 71389 and they are excellent. Los Plantronics los he llegado a ver por 91 euroz nuevos, siendo los más baratos a estrenar. For those curious, wireless charging isn?t impacted and the top section is grippy so that it doesn?t fall off the lid. I got my son the same size and style.
