When I put it on for the first time, after 5 minutes my auricle became very sick. I thought that I was unlucky and did not suit me, I hung it on the other ear and completely forgot. not felt in the ear. it turned out that the headset should be corrected so that discomfort disappears and it can be worn all day without noticing. understands my English very badly (probably a strong accent). before that there were 2 gills, in terms of sound quality no worse than plantronix. only 3 times cheaper. forced to write a review. after 4 months the headset died. The battery is still holding capacity. but the headset refuses to work
