The Coffee Bean utilizes a single 10mm dynamic driver operating on a dual magnetic circuit. This provides a unique advantage over other dynamic drivers as it makes it more energy efficient. This leading energy efficiency can be seen in the high sensitivity and low impedance that they carry. This lets you perceive your audio exactly as it was produced.
The diaphragm is made with the utmost care, composed of a mixture of polyurethane and polyether ether ketone. These two materials come together to make a diaphragm that has the flexibility to precisely reproduce sounds to the highest resolution. You’re guaranteed rich, detailed audio.
