Overall, it was Great! They didn’t carry my size so I figured I would go home and just order them online. Se pueden ajustar firmemente. So the loud explosions , footsteps, etc are hard to hear. Like others reviews on here I even forget I still have these on due to there light weight and even walked into the shower with them on, thankfully they are IP67 so after a oh crap moment I then relaxed remembering IP67 😃. The product arrived on time. I think its going to help so that I dont need surgery on my feet. The back heel on mine wore out in about 3 weeks of use . i want to preface this by saying i really wish i could give these earbuds a higher rating; i think the sound quality is great for the price and i enjoy the fact that its very balanced (not too much bass, treble or mids, it all sounds great imo). However, Firefox (without installing the beta M1 supported version) would consistently freeze and crash and it seemed to be ruled out by plugins, but even without that, certain websites wouldnt work and loading pages after each click took way too long.
