## Customer Reviews

### ⭐⭐⭐⭐⭐ Good Clear Ear Buds
*by J***E on January 27, 2025*

Nice Comfortable Ear Buds with clear sound quality and doesn't fall of your ears. As Open Earbuds, they work well if the surrounding environment isn't loud (70+ db minimum for you to turn it to near max volume to hear better) and you can hear both audio and external sounds without either interferring. I haven't played around with the touch settings too much but adjusting volume might be tricky (left to lower and right for higher). Microphone quality is decent as long as there is no winds in the background. Rotating case feels like a fidget toy and weighs a good bit. Satisfied with it so far.

### ⭐⭐⭐⭐⭐ Good quality
*by J***N on June 11, 2025*

Great.

### ⭐ They won’t last past a few months!
*by A***R on April 4, 2025*

Bought them in December, 100% only used them inside the office with the volume pretty low. By early April the speakers speakers stopped working. You can tell they were on and connected but their volume wouldn’t match. One was loud the other very low. Don’t expect to use these for longer than a few months if you buy them! Very low quality and the case is terrible, it offers no protection forcing me to buy a case for the case. Madness lol.
