The part number and UPC conform with the official Sennheiser part. I can finally start using my Apple AirPods again. If you own the original release from 2016, Beyond is a free update. Looks like were going to the pros for repair. so far, been using it on and off for the last 3 weeks and finally charged it. I had an extra piece of silicone material I cut to size to add to the diameter thickness of my weird handlebar diameter for this bike holder to clamp around. I didn?t have to keep adjusting and it wasn?t uncomfortable. Definitely something to consider if you are as interested in backyard wildlife as I am. Product worked great and never budged! I hope my less than perfect feet don?t ruin it for you, try them, they are so fun!
