I ordered the foam size large thinking they were the same as what I use that came with the earbuds, but they're a much harder foam and actually hurt my ears. Maybe the smaller size would have worked, or maybe it's just the wrong foam compound or something. I did contact customer service and they're shipping me some of the same tips that come with the earbuds, so hopefully I'm not out the money I spent on the tips because I ordered 3 packs of them.

Haven't tried them yet but they look great

I tried to buy more ear pieces for it and I couldn’t find any for them. Would be nice if there were some for replacements.

Love em. Got the Rebel wireless for Christmas and while they aren't perfect they are damn good for a first try at truly wireless. Had some minor connection issues and comfortability isn't the greatest but the battery life is highly understated. I run a full 12hr shift and still have 50% left on the buds. The case is getting its first charge since I've started using them daily and it's been 9 days. I'm eagerly awaiting a newer version from Elgin that hopefully addresses some of the minor issues in them.
While there's no phone number to call for customer service in my experience they promptly respond to emails to address any issues.

I originally bought them as a replacement for my Rebel earbuds. When I receive them. the form insert of the replacement were smaller then the originals. I thought the replacement fit all models judging by the website.
