The device itself is functional and I enjoy using it, although it hurts my ears a little because of the thickness of the right earpiece.
When I plugged it into my computer to upload mp3 files, I noticed 3 songs were already on there with a data stamp of 2021. One was a song I recognized and two were in Spanish (I think). I am disappointed that I paid full price thinking that I would receive an unused product.
Great design, sound quality is great. On the other hand the built in memory is slow.
I'm really happy with the headphones I bought. I’d love to check out your other products or recommend them to others
