The HSE-A2000 is the first model in the Hi-Unit series to support high-resolution audio sources, and is equipped with a graphene-coated diaphragm in the driver, which is harder than diamond. We worked on product development with the aim of seeing how far we could pursue "high resolution" at an "affordable price range." It suppresses vibrations, resulting in clear, distortion-free sound images and tight bass reproduction. Open up a new world with the expressive power to reproduce every sound! It reproduces clear vocals, mid-to-high frequencies, and tight bass frequencies, making it suitable for a variety of genres! ●If you want to listen to POPS and ROCK, this is it! ●Graphene-coated diaphragm for excellent sound response ●Aluminum housing with a luxurious sheen that suppresses unnecessary resonance ●High-strength filament cord that is resistant to breakage ●Bending-resistant cord bushings are used for the plug, which is the main cause of breakage【specification】 Driver unit: φ8mm high-power magnet Type: Closed dynamic type Frequency response: 5-40,000Hz Impedance: 16 ohms Plug: φ3.5mm stereo mini plug Output sound pressure level: 92dB Maximum input: 5mW Weight: about 10g Cord length: 120cm
