The adjustable headband is made of solid stainless steel on the inside and wrapped in high-quality leather on the outside, ensuring comfortable, fatigue-free listening for hours. The HE-R9 from Hifiman delights with high detail fidelity, a wide soundstage, and plenty of musicality, making it suitable for both on-the-go and home use thanks to its comfortable closed design.
