I was looking for a set of Bluetooth headset since I bought my iPhone 7 at the beginning of the summer. I tried some, different brands. When I found this Alfawise HQB thing, I read all the tech specs, and I thought I give it a try.I just arrived yesterday, so I started to test it. Running test is still on the way in the near future (on Thursday to be specific), but I tested on public transport and in my room. It sounds good, it has nice bass, and treble as well, so I enjoy all my music comes from it, either I listen to youtube, or simply just my iPhone's music library.It fits the ears well, and from this small period of time, it's battery lasts 2 hours straight, then you just have to put it in the charger, and the fanciest thing: the charger signs the percentage of the charging. So all in all after a half-day of testing I love this product.
