I bought the headphones thinking that they would accurately reproduce the sound of footsteps and shooting in FPS games (for example, PUBG), they do. But I decided to go back, I couldn' t put up with the crappy sound delivery on anything else. They grunt during music, they can' t handle the bass and when the volume is more than 50% they grunt practically all the time. In the application, it is possible to set,, THX audio,, - this results in deeper and more intense sound, but also more grunting. The previous Creative Sound Blaster headphones, maybe more than 10 years old, are much better at delivering music and the sound from them is cleaner. I understand that these are gaming headphones and not music headphones, but even then they shouldn' t make noise during normal youtube songs/watching movies. In game the sound is perfect until there are explosions, engine sounds, other coarser and denser sounds, then it grunts even there. The microphone is lousy, downright lousy, even after trying to set everything possible. I expected the range of the headphones to be somewhat greater. I chose wireless because of the freedom of movement around the apartment in the block of flats, when running away from the game, listening to music, etc. that is not possible here. In a panel house, they are not able to reach further than 4-5m and there must not be a wall in the way. Stupid plugs from aliexpress for 300 CZK play in the whole apartment. Next, I made a mistake in my choice, I assumed that the absence of a rotary adjustment of each earpiece would not be a problem at all - wrong, the earpieces press in the back and bottom of the ears. They are not suitable for larger heads. Maybe I had a defective piece, but since it didn' t even fit on the ears, I wasn' t going to try a claim. It' s the first product I' ve returned. I spent the whole day trying to adjust my headphones so that she wouldn' t snort. He researched videos on youtube etc.,, how to do it,, and still in vain. I recommend looking for another manufacturer, I have no ear for music, but this really didn' t work.
