Yes there is at times. I usually get refurbished items, because they're cheaper of course. 99% of the items I've bought as refurbished have lasted me awhile. So far the only 2 instance s I've had issues with was, a computer monitor that I got refurbished that I had to take off sleep mode, because it would go into sleep mode, and when it would "wake up", it started going crazy trying to wake up. But I just took it off sleep mode, and problem solved. The other problem was much more serious. I ordered these same earbuds from another site as refurbished. Those turned out defective. I charged them, and I assume they were fully charged, but my S20+ could not connect to them. So I returned them to that site, and bought these refurbished here on Best Buy, and so far they've turned out to be great! I've not encountered any problem. As soon as I charged them, and opened the case, my phone started the connection process. I hope this helps you.
