Pros: \n - Very good music quality\n - Almost undetectable (nano-seconds) delay with videos\n - Good phone quality - almost as good as Samsung Buds Pro. \n - Light-press buttons, almost touch-sensitive\n\nCons:\n - Lightning charging port, not USB-C\n - Ear loop is a bit big, not adjustable\n\nI had purchased the JBL The Rock Project earbuds before these. Those were great and fit very comfortably but the phone call quality was horrible. I returned them and got these and boy are they an improvement! The phone call quality rivals that of Samsung Buds and the music is very good with better bass than JBL and Buds. \n\nMy only complaint is that the ear loop is a bit large. They sit fine on my ear and even during strenuous workout sessions, they don't fall out or anything, but you can clearly see the loop sitting with a gap at the top of my ear. My ear does start feeling a bit sore after a few hours of wearing them but I have very small ear canals so no points deducted there. \n\nAlso, compared to the JBL earbuds, the button on these is very light. I felt like I was pushing the buds in too deep when pressing the JBL button but on these it's so light that the earbud doesn't move or feel pushed in. \n\nOne more thing: I wear glasses and I've seen both good and bad reviews about using these with glasses. I've used them for the past two weeks and so far I have absolutely no issues. I run with them and it doesn't bother me at all. I guess it depends on what glasses you wear and how the ear loop sits on your ear. For reference, I wear Costa Forest Reef 300 prescription glasses. They sit flush at the crevice of my ear and head and the powerbeats sit on the outside of the glasses.
