A:AnswerThey should connect just like you would any other device. I've never had a issue . You might have a defective pair. Have someone else try to connect them to their phone or whatever. You've probably already solved or returned them, if not I hope this helps.
A:AnswerI can run and power walk up to six miles in one workout in these earbuds and they’ve never fallen out or even seemed loose. Just ensure you use the correct earbud prong (which comes with four different sizes in the package) that contours to your ear shape and you will have a snug comfortable fit.
A:AnswerIt depends. I’ve left my phone about 50-60 feet away and that’s when music would start cutting out. I drive a forklift at work and I’m constantly walking away from my phone
A:AnswerThey should, although I'm not certain on specefic devices but universally they work with most devices. I use mine with a Google Pixel 5 and a Vankyo s30 tablet with no issues. Hope this helps a little.
