I am looking for perfect case for my Jabra Extreme. It alway drop from Lanyard which come right out of the box, I bought another case from Amazon, but It is too big to hang around my neck. When I see this, I am not should be dimension of product since it state in inches which the real unit is in Centimeter. I took a risk to order it, and it pay off. I ripped off plastic for headphone winding and put my Jabra Extreme on, Perfect fit. I used my old bluetooth case for my Super-Fi 4vi and throw away plastic part out!!However, there is a little downside of this product. Zipper is not quite smooth and you need to be patient to zip it up!
