Enough for 5 days for 2-3 hours a day without charging. If about the sound: the sound is not bad, the middle is good, the top is normal, the bass muffles the sound strongly and does not bass, but only reduces the volume as if, but it is, incomprehensible but there. Vacuum headphones are better if you like music and you need headphones for music. Haven't bought a Pro yet, but people are praising me and I'll say that I have Sennheiser wired vacuums and I'm enjoying. brr. high. Do I recommend them? For this money, never, such a sound is given out by normal ears for 1000-2022 easily or even better, you pay for the brand, the wireless function and that's it. If the jack had not been removed, then I would have stayed on the wired ones, sometimes I listen through the adapter, but it's inconvenient, I'm afraid to tear everything off. So normal ears and the sound is just not bad, but good, but not great.
