The CK7s are Audio-Technica's high quality inner ear earphones. Weighing only 10g, they are designed with a simple and classic look and are great headphones for outdoors, as their natural snug fit means they are passive noise-cancelling, helping reduce unwanted background noise.
The silver earphones feature an 11mm diameter driver that delivers deeper bass, extended treble and higher fidelity yet small enough to fit into your ear. The neodymium magnets in these earphones deliver maximum energy in minimum size, they are far more powerful than conventional Samarium Cobalt or aluminum magnets.
