The headset is not as sturdy as I thought itll be. Look like made for elephant feet. Attached it to our keys and Amazon Firestick remotes with the gel cases. I bought them as a replacement for my wifes EMU slippers from Australia and She is very happy as they have a fluffy generous Lambswoool upper and a good traction sole. The pain was still there the next day and thankfully he got an appointment that day with an Ear Nose and Throat Specialist. All parts are labeled with stickers. Springs are tight and it holds position well. I was new to the concept BTW make a template do not take the motor off of the base put a piece of cardboard underneath it . With something less than $40, I highly recommend it. The sizing appears similar between these and the Shure tips, I had meduim Shure and bought Mediums in these and they are the correct size.
