The HE-R9 from Hifiman is a closed dynamic headphone that impresses with its clarity, excellent spatial imaging and balanced sound. With its warm sound character and striking appearance, the HE-R9 is a top headphone for enthusiastic music lovers. The closed design ensures that ambient noise does not penetrate and the music can be heard without interference from outside. In the low frequency range, the bass is handled cleanly and bass-heavy music is also reproduced very precisely down to the lowest frequencies. The transient response is lightning-fast, ensuring a gripping, atmospheric sound. Hifiman uses its proprietary Topology cone with a special nanoparticle coating. This cone achieves a higher sensitivity and delivers a wonderfully detailed, natural sound across all frequencies. With an impedance of 32 ohms and a sensitivity of 100 dB, the HE-R9 can be used just as well with a home system as with a portable playback device such as a Hi-Res music player or a smartphone. The HE-R9's housing in a shiny red-brown metallic finish epitomises elegance and robustness. The size-adjustable headband is made of solid stainless steel on the inside and covered with high-quality leather on the outside, which ensures comfortable, fatigue-free listening for hours on end. The HE-R9 from Hifiman offers a high level of detail, a wide sound stage and plenty of musicality and can be used both on the move and at home thanks to its comfortable closed design.
