The headphones have a too-large size, but the fit is acceptable; nonetheless, the equivalent AirPods Pro have a far more comfortable fit.
The reduction of noise is beneficial, but only if there is no wind present. As a cost-cutting measure, the manufacturer did not install meshes on the external speakers. As a direct consequence of this decision, the listener will hear every gust of wind (in the same airpods pro, this effect is also there, but almost not noticeable)
Due to the model's substandard microphone, wearing it as a headphone is nearly difficult (the only option is to remove one earphone and speak into it).
Horrible case. The quality is also not extremely credible, and it is large, which makes it very easy to soil, and it quickly loses its presentable aspect (the lid is noticeably loose, the magnet is rather weak).
There is occasional disconnection between the headphones and the phone (ears are paired with iphone xs max). They hang up approximately once every seven days (they simply do not connect to the phone, only throwing them into a case with subsequent extraction helps). It also happened more than a few times that the headphones did not charge at all while they were in the case, despite the fact that the case itself was fully charged.
I noticed that the headphones used their batteries in an inconsistent manner; the left one ran out of juice thirty minutes quicker than the other one.
Even when using a proprietary program, neither the case nor the headphones have a standard charge display of any kind. (the progression of percentages from 100 to 70 to 50 to 20, and then to death, is not at all helpful because 70% can easily and rapidly become 20%, and after that, a shutdown occurs).
