Review: I LOVE THEM! - I have tried so many headphones and earbuds. With and without the wires. I actually prefer the earbuds with wires. These are hands down my favorite I've had so far and I plan on purchasing more. I love the way they wrap around the back of my ear to keep the wires out of the way. And they are super comfortable and the perfect size. The sound is nice and you don't hear any outside noises while in use and they are really good quality made for the price. If you are deciding on whether or not to purchase these you should I promise they will not disappoint.
Review: quality-price - I loved them, they have a very nice design, the sound quality is very good although the bass presence is a little low but if you have Spotify and configure the sound the bass improves a lot, for the price they seem very good to me, I will definitely keep them!!

### ⭐⭐⭐⭐ Used product
*by M***L on August 22, 2024*

These things work fine. Sounds good and the fit is nice. My issues is I paid for a new product but received a used product. All the items inside opened with the baggies torn. Not the end of the world, they look and work fine but you should get what you pay for. *Update* Seller reached out about me receiving open used headphones and made it right. So based just on the headphone performance I have updated my star rating.
