Review: Awesome open ear pods, super comfortable to wear - This is an open ear pod from Trufree branded which I can wear without any pain or discomfort from sweat or long use for hours. My first impression was how nice the packaging was, the sturdiness of the earbud case. The design is excellent. The earbuds had a full charge and were easily paired with my Android phone. I listen to a lot of podcasts and found the audio was clear for the spoken word. Then I wanted to see how they handle the music on my Playlist and was pleased to discover that the preformed quite well. This with added awareness of sounds nearby. In ear pods are a pain or discomfort, they may fall off, but this design is just awesome. I recommend this open ear pods. They are worth their price. Five star rating for these pods👍

### ⭐⭐⭐⭐ Meets expectations
*by M***L on 8 February 2025*

Before trufree earbuds I bought 2 different open war earbuds, I returned both of them as they were not meet my expectations related to sound quality & other functions, but when after I bought trufree I can say this is the open ear earbuds I’m looking for specifically quality of sound, dual connection when using laptop & cellphone at the same time, only the issue is with little bit big case which I hope company to work on it & making it smaller for easy carry on in pocket or bag
