The Hercules Light Show Headphones are that mix and blink on the beat. They have drivers for advanced listening. They are great for DJ monitoring, studio and production. They have enough decibels to preview even close to PA speakers. There is a strong playback level from any audio source. Wide frequency bandwidth, to monitor all audible frequencies, and large 50 mm drivers. There is a deep bass response and crystal clear sound. The Light show headphones blink on the beat highlighting the white logo in in both ear cups. The headphones are part of your performance, as they blink in sync with inside/outside sound. Easy 1-ear monitoring, easy folding for mobility, and extending arms for large and small heads. The soft, large ear pads: isolate the DJ's ears from ambient noise, and the closed-back ear-cups prevent sound from bleeding out. These headphones don't press on the user's head, thanks to the ear pads' width and softness, forming a barrier around the ears.
