I don't write a lot of reviews. It has to be really bad or really good for me to take the time. I have to say I am impressed with these cheap earbuds, but I only use them for one situation and environment; mowing. I use them in conjunction with earmuffs to seal out as much noise as possible. To caveat ALL of my ratings here, I am giving them with one overall consideration of these earbuds; THE PRICE. So, for the price they have been pretty amazing. I have used them for a year and a half now. The buds are simple to use and pair with my Android. The tips are pretty comfortable and seal well, but not enough to totally eliminate the sound of a mower engine. The sound quality is also very good when I compare them to my more expensive Bose and Klipsch earbuds that I don't want to risk destroying while working outdoors or mowing. What I have been most impressed with is there durability when it comes to how I treat them; especially the battery. They have gotten hung up on tree branches a few times and have taken that well, but most impressive is that the batter lasts forever on a charge and they keep working even after I just leave them sitting in my shop. My shop is not insulated, heated or cooled. I leave these earbuds out there when not in use. In the winter I don't even use them and they just lay on my mower until spring. When I went to use them this spring, They still had a full charge after I charged them in October when I put the mowing equipment away. At times, the temp is 0 degrees F or lower out there. In the summer, I mow typically once a week for 2 hours using the buds and I leave them in the shop, which is anywhere from 100-125 degrees F during the day. Last week the battery was at 60 percent! I cannot believe that they still work and sound good after the temperature deviations during storage OR that I have only charged them once (when they weren't even fully discharged). Mine may be the odd set, I don't know, but I am tempted to get another.
