I think the headphones have a problem with the battery or the packaging, but I don't know that for sure yet. The initial charge, however, was not maintained for very long. They won't last more than an hour if they have active noise cancellation. After using them for over a year, I can confidently tell that they are not worth the price. They perform so poorly because the battery is so weak, and since the difference in distortion between the left and right ear has grown over time (the right one discharges substantially faster than the left 20-30% difference). After a month of use, another snag manifested itself: the earpiece might not charge while stored in its carrying case. It's unclear what's linked, however I cleaned the contacts and made sure the battery was good. After stowing it away for the night, you can wake up to a meeting in Discord and 20% volume in your ears. They connect without any issues, but now they can abruptly drop off with a half charge from the laptop, which is a meter away from me, and this is a problem that has already been highlighted by many people here as something that can be "solved" with firmware updates. The icing on the cake is that I recently purchased a pair of Freebuds 3i and discovered that they suffer from the same issues, although with a longer-lasting battery. In sum, there is only average noise, and inter-device connection management functions passably, but, as I've already mentioned, there are several annoying snarls. I refuse to spend any more honor money on aural stimulation.
