I purchased these to replace the Mpow Flame light that I had lost one of the earbuds too. I have gone through a couple of these.What I do like is the charging case. It is pretty slim, it is USB C, and it also has a display to show how much of a charge it has. This is super helpful. It also has volume and connect/disconnect buttons. This has not yet had any charging issues, but I have not owned it for very long.Now for what I don't like- They do not fit my ear that well. It may be the shape of hook, the length of the arm from which the speaker is mounted, or some other variable. The hook keeps it in place, but it never feels as if it's in my ear properly. I also think the sound is not so hot, and for 50 dollars I was expecting more. It is a little treble heavy on the heavier frequencies and just sounds like a cheap driver.My previous headphone was the MPow Flame Lite. The charging case is bulkier and bare and there is no digital display. With that said- these are now 1/3 of the price. What I do like is that they fit my ear like a glove, and the sound quality is phenominal. It sounds like a much bigger driver. I am not an audiophile, but it really sounds great. Maybe it is the mid that come in fuller giving it a rich sound.I have had some charging issues. Sometimes I find that only one of the headphones are dead and the other is fully charged. However, fit and sound are my most important details so these are my favorite. For the price I can purchase three and keep them in different places. If I lose one or have a charging issue I can replace it with the extra. This makes much more sense than keeping the aI do not more.Edit: I changed from 3 to 5 stars. I have owned these now for almost one year, and use them probably every day. There has been no decrease in performance or battery life. I was so accustomed to my previous ear buds that I did not like these much at first. However, the sound is balanced, the battery life is great, and I really like the charging case. I have never actually times the batter life, but it is probably about 7-8 hours on a full charge. There are sooo many choices now for bluetooth ear buds, but these are a safe bet and most people should be happy. I am however not an audiophile, and someone who truly is may want to spend more on a Bose, or whatever the best ear buds are nowadays. My previous ones were more bass heavy, but these are better balanced. They do stay in the ear, unless I go to lay down on my back; I then have to push them back into my ear.
