Review on Experience Ultimate Sound Quality with Edifier NB2 Pro True Wireless Earbuds - 6 Mics - Hybrid Active Noise Cancelling - Bluetooth 5.0 - 32H Play Time - USB-C - App Control - Black". by Kio Proviax ᠌

When listening to music, one gets the feeling that the headphones saturate and overload the sound at the output. 8-10 kHz cut the ear and do not allow you to enjoy listening. Snare and Hi-hat will spoil all the raspberries with their crunch, which is extremely sad, because the low and medium frequency ranges sound great (let's attribute 8-10 kHz to high frequencies in this case). I corrected it with an equalizer (Yes, I forgot to specify, Edifier does not provide an equalizer in the application. Suffer with third-party programs). I got a more or less favorable picture, but the main problem cannot be solved. Headphones at the base maximum volume display artifacts (crunch) at saturated low ones. You lower the volume bar by 1 slider: the sound is clear, but the volume is not enough. In general, sadness
