A:AnswerThe sports are a bit more gainer / course so they grip better. Sport is still comfortable but little less fidelity in sound but far better than anything on market...
Jaybird Comply's are made specifically for Jaybirds.
Comply makes earbuds that can be used in a variety of other manufactures earbuds...
But these are specifically designed forJaybird.
They are on sale now for $9.99 so I highly recommend you get a pair and try them out. Get the 2yr protection for $6.99 because they will wear out and then you can simply replace all of them for free...
Again...
Sports grip a lot better and have slightly less fidelity overall.... But are good...
I tend to like the isolation comply better because sound difference is noticeable because of the extra isolation from ambient noise
