It protects my Case every time. BUT, these are so cute and so comfortable that I HAD to write a review about them. I dont like that its too unstable to use outside if there is a slight wind or in the grass. Contacted Jabra but no resolution yet. They are a higher quality stainless steel and worked very well. Again I was thinking these were low priced bc of bulk. Whatever it is, only Vol - works, Vol + calls up a prompt on screen asking which assistant youd like to use. The ear pad locking ring is too small. The HD 4. These run narrow.
