Very good sizes of ear bud and they are so lightweight than I have had before, very comfortable and secure. I normally take a size 6 womens, but I ordered the 5. The awareness and conversation modes worked once. look forward to using it. It must weigh close to 30 lbs. The sound would flicker quickly in one or both ears, then come back normally. I do own more expensive earbuds like apple earbuds pro but sometimes it’s really good to have some cheap option available if you loose or break while traveling so if it’s lost you don’t get hurt much. It had a corset effect almost. on a 6’ bar so far and have had no issues whatsoever. Sad because a waited a while for it and my friend cannot even use it,
