PUMP Audio was inspired by a shared love of Dance Music. Most of the world’s leading headphone manufacturers make headphones with a “flat frequency response”, meaning that they reproduce slavishly the sound that’s fed in to them, giving every frequency exactly the same priority. That can be great for certain genres of music, such as Classical and even Rock. But for other genres such as Dance Music, the music sounds much better when listened to with a ‘richer’ or ‘warmer’ sound signature. Headphones that have a flat frequency response can sound just that: flat. The PUMP Zeus is specifically tuned to have the “club sound” sound signature that Dance Music lovers love.
