Linsoul 7HZ AERO 1DD Earphones Equipped with Upgraded Dynamic Driver Equipped with Plug Deep Bass Ergonomically Designed Adopts Exclusive Tuning

【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.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. Super linear dynamic driver meets all sound quality expectations. The superlinear internal magnetic dynamic driver used in AERO has internal soldering structure and internal magnetic arrangement. This design significantly increases the magnet height and improves low frequency performance. This driver unit has been upgraded with a new internal cavity for more precise control of the position of the resonance peak. Additionally, a new damping solution has also been implemented to improve production consistency. Strip away the decorations and return to purity. Remove external decorations and packaging and return to the true essence of the product. AERO features a new generation internal magnetic dynamic driver to reduce distortion and optimize tri-frequency performance. This provides more detailed mid-high frequency performance and reproduces more elaborate sonic details. Relying on strength and performance to crush impurities in industry. Thanks to the strenuous efforts of 7HZ's acoustics team, AERO boasts acoustic metrics on par with other so-called flagship dynamic driver earphones, with excellent frequency response and minimal distortion across the entire range. This ensures faithful sound reproduction with natural and smooth tonality. AERO's sonic style is more neutral and less colored, emphasizing natural sounds and authenticity of instruments. AERO's overall resolution and clarity has been improved. Timeless ergonomic design. Leveraging 7HZ's years of experience manufacturing custom-grade in-ear monitors, the AERO seamlessly combines superior acoustic performance with a sophisticated aesthetic, offering a more comfortable and ergonomic fit. Adopting a new type of oxygen-free copper dual-core cable, this cable minimizes signal loss and reduces audio attenuation, resulting in superior audio signal resolution and conductivity, achieving high-quality audio transmission.
