【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.
[Warmth of the Sun: Open headphones that will be the brand's entry model] Apollo is the brand's entry model that was developed to allow more users to experience SENDY AUDIO's brand identity of excellent fitting, pure sound, and craftsmanship. Apollo is an open headphone that is lightweight and comfortable to wear, with a design and sound that evokes the warmth of the sun.
[Planar magnetic driver with ultra-thin, high-rigidity composite film and 68mm large-diameter diaphragm] Apollo is equipped with a planar magnetic (planar magnetic field) driver with low distortion over a wide frequency range. The diaphragm uses a 68mm large-diameter diaphragm made of an ultra-thin and highly rigid composite membrane. This results in natural vocals, deep and solid bass, bright highs with clear detail, and a transparent and clean soundstage. The driver structure is designed with an optimal magnetic circuit and magnetic distance to balance resonance. The high internal damping of the composite membrane diaphragm provides natural, soft vocals and solid bass. In addition, the ultra-thin and highly rigid base material that is responsible for the high frequency range can extend the reproduction frequency up to 40KHz, brightening the high frequency range and clarifying details, providing relaxed and comfortable listening.
[Unique QUAD-FORMER Technology] Apollo uses a unique QUAD-FORMER technology that consists of a total of 4 coils, two on each side of the diaphragm. Planar magnetic drivers consist of double magnets, double side coils on the diaphragm, and double coils on both sides of the diaphragm. The coils are well-balanced on the diaphragm. With two coils on each side of the diaphragm, there are a total of four coils on the diaphragm, and the diaphragm vibrates the same at the same frequency. Double-sided magnets exert the same magnetic force in the field. QUAD-FORMER technology enables highly efficient electroacoustic energy conversion, resulting in ultra-low distortion, extremely high driver response, and excellent consistency.
[Headphone housing is made of solid natural rosewood] The headphone housing uses the brand's signature wood processing technology and uses rosewood, a solid natural material with a beautiful luster. The surface is painted with a glossy finish, creating a smooth and elegant look. The ergonomic headband is made of soft goat leather, making it comfortable to wear and less tiring even when worn for long periods of time. The ear pads are made of high protein leather and memory foam, and have a bowl-like design that reduces pressure on your ears while providing a soft and comfortable fit. In addition, L and R markings are placed on the inside, making it easy to identify left and right. The ear pads are removable and can be easily and conveniently replaced. The cable uses approximately 2m of 6N OCC 4-core Litz wire and uses a 4.4mm balanced plug. Comes with a 4.4mm to 3.5mm conversion plug, an accessory bag made of linen cloth, and a sturdy original carrying case.
