I’ve been using one of these for about 6 months. The audio quality is decent. I use it mostly for listening to podcasts and audio books around my house. The speaker function is great if you don’t like the discomfort of earbuds/headphones and want to reduce the risk of hearing damage. It’s still nice to have the earbud option when going out in public though. Battery life is great, they’ll last 8 hrs on speaker with no trouble and longer on earbuds. They’ve also preformed well in the rain. The biggest problem is that I can’t really use them for phone calls, when ever I’ve tried I get constant complaints about my voice quality. That said I do use them a lot on long conference calls where I don’t have to speak much so I can keep working or running errands while I listen.
