The ear buds came packaged very well from the factory. They have numerous options for fitment and I was able to find a size that fit comfortably. They sound like $100+ head phones for a fraction of the price. They stayed in the ear comfortably while working out and I had no issues after 2 weeks not charging them. It was extremely easy to pair them to my phone (pixel 2 xl) and they have not lost connection or had any issues while I used them for my work outs. After weeks of testing I can confidently say that I've put this product through many physical challenges and it has passed with flying colors.
I highly recommend them especially for the price but even if they were a bit more expensive I'd still get them. Please let me know if you have any questions.
