BlitzWolf did it again and brought us the BlitzWolf BW-ANC2 bluetooth headset, which gives 30 hours of use on a single charge and the manufacturer also equipped it with active noise reduction to be in blessed silence even in noisy environments. It can be said that it is quite cheap, as it is currently available for 38.99 USD.
It is a bluetooth headset with a neck strap and so the rough operating time is already understandable, as the manufacturer has placed a large battery on it. The manufacturer promises crystal clear, powerful sound thanks to the large 13mm speaker.
During active noise filtering, ambient noise entering the ears is strongly suppressed by emitting sound waves of the same amplitude but in reverse phase (anphase) to the original sound. That is, unlike passive noise reduction (e.g., earplugs), it analyzes the noise and extinguishes it.
It can be turned on and off at any time, making the sounds of the environment more audible. The 200mAh battery of BW-ANC2 can be used for 30 hours on a single charge and for 20 hours when active noise reduction is on.
