Ultimately, I wouldn’t stress out too much over it. In the end, I think they’re both going to suit your use cases just fine. Unfortunately, Anker has a quite confusing and very populated lineup of earbuds and with the lack of a helpful comparison chart tool on their website, it’s difficult to track down all of the miniscule differentiators of each model. Sorry we can’t help more.
Perhaps @AnkerOfficial can provide some further insight into the nitty gritty details.
