The headphones are excellent. I will compare with the Eli 10i Fit, also from Baseus: significantly lighter, more comfortable, and organic. They fit better on the ear and do not cause discomfort during long-term wear.
The earphone's form factor is anatomically tailored to fit the curve of the ear canal and fits perfectly, blending seamlessly with the frame of sports sunglasses without any unnecessary pressure.
The volume range has increased. The sound quality is comparable, there are more settings, but there are some nuances. The LDAC codec cannot be combined with other settings like bass enhancement; without it, the sound becomes somewhat dull.
The case has a three-color battery charge indicator, but the headphones do not have indicators. That's why there is a physical, not a touch-sensitive, control button on the teardrop-shaped pendant. This is a huge advantage because you can sleep with headphones or listen to audio while lying on your pillow without any interruptions from accidental touches.
The headphones cost 3385 rubles, which is quite adequate for this product.
