Just got my new accessory kit with the ear fins. They are way more comfortable than the ear hooks for sure, just don't feel as secure even thought i can shake my head quickly and the ear fins don't come loose.
^^^ I just received this as well. The earfins are the most comfortable experience I've had with the iSine 20's. The earfins are labelled "right" and "left" so it is easy to see how they fit the iSine's. The earfins are a secure fit in my opinion. The supplied earhooks are also different from the originals and the fit has improved. This $25 accessory kit is excellent. Highly recommended.
