I go to the gym with them, they hold up well. Very pleased with the size of the battery. The case is too big, of course it fits in a pocket, but not very comfortable. Its pros: They fit tightly, good BT connection, hold charge for a long time Different cons: Not comfortable elastic bands on the headphones (not those that are inserted into the ear, but additional ones), I took them off, it’s more convenient without them. For such a price, the transparency mode is not very good, there is too much extraneous noise
