The smallest tip was way to big. Bad fit in general in ear and they did not really fit well on my Jabra 75t
Excellent quality, fit Jabra Elite Active 65t perfectly, and still fit nicely inside the charging case. I use the medium size (regular) official ear gel tips and the medium size of these foam tips fits well, although perhaps a little too tight (I'm tempted to try the small size to see if they fit more comfortably). Regardless, I'm very impressed with the product and recommend them.
