Quad ERA -1

Magnetostatic headphones

Quad's effort to produce extremely natural sound is using the best and latest technology in the industry. This way we get as close as possible to the requirements that the artist has created for his music. This principle is also perfectly respected by the magnetostatic ERA-1 headphones.

The structure of the Quad ERA-1 headphones is based on an extremely thin membrane, which is thinner than a human hair and weighs less than the air mass it displaces, but has a very durable and flexible structure. The precisely designed magnet structure uniformly maximizes sensitivity and sound pressure. The end result is an authentically pleasant musical sound experience, which the listener will enjoy as an audiophile for years to come.
