Where do I begin. I don't think there's anything I dislike about these headphones. The packaging is nice and modern, Looks premium so is a nice looking gift for someone. The case that comes with headphones are awesome. I do like the rotate feature that closes the cases for headphones. The case charges the earbuds a few times over as well which is awesome. The ear buds are a matt finish which makes the product look more premium. I find some of the gloss finish ear buds give it a cheap look. The bluetooth connects well and is easy to pair. Both the case and earbuds have a very premium feel, the ear buds fit nice and snug in the case and the twist and close feature works really well. The battery life is really good. I've used the buds for around 3 hours during first use and it still had more battery. The earbuds itself have a small rubber part that hooks inside the ear, this allows the ear phones to fit nice and snug and don't fall out. I've used the earphones to train at the gym a few times and they've not fallen out so far. Finally the most impressive things about the earphones so far have been the sound quality. It has some crazy bass. Very deep and precise. The high frequency is crisp and the overall sound is very well balance. The functionality is great. Works very well with my iPhone 6s. skip, previous song, play, pause, volume up, volume down. Also works as a single ear bud. Very happy with these earphones and will definitely recommend it to anyone who is looking for a decent pair of wireless earbuds.
