I have encountered some situations in TF mode where the sound seemed yo break for a little time.
Also, from a previous discussion, I understood that there might be software updates in the future for my headphone, but I can't find any information about such things.
I bought it for my partner as a Christmas gift. He has more earphones like this but since he got it, this is the only one what he wears during his workouts :D perfect fit, incredible sound, and does not rub the skin behind the ears when sweating. He loves it
Basic sound, not good fit in head for bone conduction, Basic player, storage folders but plays alphabetical. order don't care what folder the song placed, no controls or functional button not working as expected - totally one month to get the product and one week of usage reveals this a fake product from delivered from Chaina
