Many advertise eight hour battery usage but I have not found them able to last more than four or five hours of media playback. Well made, good fit. They give good support in the arch and are very comfortable. Tray sets about two inches from the bottom. I was happy to find that these three products could be bought as a set as they worked wonders with my normal to oily skin. Overall I love these earbuds. Other reviews found this annoying, I did not notice it. Its now three times faster on download speed tests and 20% faster on upload. Another fail. In use, this adapter is equally as happy on my Windows 10 laptop as it is on my Samsung Galaxy S20 mobile phone.
