## Customer Reviews

### ⭐⭐⭐⭐⭐ Great headphones
*by R***S on July 8, 2025*

These are great headphones! They are very easy to use. The directions were easy to understand and follow. Connected easily to my phone. Held charge for quite some time. Not much background noise. The quality of the music is superb. Great quality for a cheaper price point. Highly recommend.

### ⭐⭐⭐⭐⭐ Long lasting, great quality, and comfortable
*by S***N on April 7, 2025*

Love these! I have small ears and struggle with finding in-ear ear buds that fit. I have hours of conference calls a day and over the ear headphones just make my ears sweat. However, these are the perfect! They fit nicely on my ears and are really comfortable. The sound quality and audio is great. And the battery lasts a long time. Great value for the money as well.

### ⭐⭐⭐⭐ Great set
*by G***R on May 3, 2025*

This was my 1st pair of bone buds. The battery lasted a few days. The sound was decent. They had trouble staying on my right ear idky. They're lightweight. Anyway, I work in a lab...if they'd fall off they'd get kicked. Eventually that right bud came apart and had a mind of its own. Good set for a 1st pair to see if they suit you.
