Finally I convinced myself and bought them. I state that I come from experiences with Bose Earbuds QuietComfort II, ASTELL & KERN UW100 and now Pixel Buds Pro. As soon as I inserted them, the first impact was unsettling. Ok great presence and clarity in the highs and mids but the lows...oh my God. I'll try to get used to their timbre. The thing I liked the most was how easy it was to put them on. I had bought the xm4s and returned immediately. It was impossible for me to wear them. Fortunately, these are something else entirely. I did my usual jog this morning and they didn't budge a millimeter. I had a connection problem setting the priority on sound quality. My Honor magic 5 pro automatically sets the connection at 990 kbps and it's probably too much for bluetooth. I fixed it by setting the adaptive quality in developer options. I don't understand the various reviews and opinions praising the ANC. For me it is non-existent. Especially when compared to Bose or even Pixel Buds. In fact I took it off and the music sounds even better to me. I'm going to try them again trying to get used to the poor bass sound of Sony. We will see.
