BZ-PRO9 is a satisfactory product.
Select:BZ-PRO9
It's not for a long time, but I used it for the first time today and it's comfortable to wear compared to earphones. I mainly use it for calls and watching YouTube, so I'm satisfied. I haven't worn it for a long time, but I think I'll use it while riding a bicycle without any discomfort. And personally, I didn't feel the weight well, so I'll try it tomorrow. I'll have to wear it all day. For now, I'm satisfied with the product.
