【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
・Magnesium dome diaphragm A thin film of magnesium is used in the dome section, which requires light weight and high rigidity.By efficiently transmitting the vibrations generated by the voice coil to the dome section, reproduction of ultra-high frequencies up to 120kHz is achieved.
・Fibonacci pattern grille The grille of the driver unit uses a curved pattern based on the Fibonacci sequence to equalize the openings. In addition, by using high-rigidity materials and making the crosspiece as thin as possible, it does not impede air propagation and achieves smooth ultra-high frequency reproduction.
・High-magnetic neodymium magnet The highest-grade neodymium magnet with a maximum energy product of 400 kJ/m3 is used in the largest volume for Sony headphones, and is also equipped with a newly developed high-efficiency magnetic circuit that minimizes magnetic flux loss to maximize total magnetic flux.
・Large-diameter diaphragm The large-diameter 70 mm diaphragm, which is larger than the average human ear, reproduces a nearly flat wavefront. The sound wavefront is wide and flat, creating a natural sound that feels like listening to a live performance.
・Achieving micro-sound reproduction with newly developed resonance-free housing Spatial resonance is eliminated by using an acoustic register on the entire surface of the housing and optimally controlling ventilation. Improving the audible S/N ratio by eliminating the resonance peculiar to closed-back headphones.
