Given the length of the project, it is difficult to say for certain. Every other day, I give it a charge. As these are my very first wireless headphones, I can only speak in generalities at this point. It would appear that there is no sound, yet there are bugs that ruin everything. I'm going to experiment with more pricey options. The benefits of it include: They are comfortable to wear and do not put any pressure on my ears, even though I wear them for two to three hours of listening per day. When it works properly, the sound quality is about average for the price. On the stock, I made a purchase for 2022. fold up into a convenient size. Got cons: I guess I'm so "fortunate," but very often buggy (it loses the phone even a meter away from it and the sound with bad distortion.) Got pros: I guess I'm so "lucky" that I got it for free. I tried it out on a few different phones in addition to the player, and it worked the same way +/- did. It is recommended that you carry the source in your left pocket so that you do not obstruct the use of your hand.
