Key Features & Technical Highlights

• Driver Configuration:
  Massive 85mm planar magnetic driver per side, featuring precisely matched neodymium magnet arrays, an ultra-thin high-stability diaphragm with embedded conductive traces for even current distribution, rapid response, and natural, effortless detail retrieval.
• Sound Signature:
  Musical and engaging with a balanced-warm tilt—clean, punchy bass that's rumbly yet controlled (great sub-bass extension without muddiness), full-bodied and rich mids (vocals shine with sweetness and presence, especially female vocals in pop/K-pop), and airy, extended treble for sparkle and air without harshness or fatigue. Reviewers highlight its snappy transients, exceptional resolution, wide staging, and addictive fun factor—more "fiery and exciting" than purely analytical, making it versatile for rock, electronic, pop, and beyond.
• Specifications:
  • Sensitivity: 92dB/mW ± 3dB @ 1kHz
  • Impedance: 25Ω ± 15% @ 1kHz
  • Frequency Response: 10Hz – 40kHz
  • Total Harmonic Distortion: ≤3% @ 1kHz
  • Rated Input Power: 100mW / Max: 300mW
  • Easy to drive from most sources (phones, dongles, DAPs)—no powerful amp strictly required, though it scales beautifully with better sources.
• Premium Build & Comfort: Advanced 5-axis CNC-machined aluminum alloy housing for lightweight durability and resonance control. Ergonomic design with plush, durable leather earpads and headband for all-day comfort. Open-back architecture provides natural breathability and immersive openness.

Why Choose OX Demon King?
As TANGZU's inaugural headphone, the OX Demon King punches way above its weight with planar speed, low distortion, and a lively yet refined tuning that makes music feel alive and dynamic. It's praised for being intensely engaging, musically addictive, and a fresh take on planar sound—perfect for home listening, studio reference, or upgrading from IEMs to over-ears. The open-back design excels in spaciousness and imaging, though it's best in quiet environments due to sound leakage.

The Legend of the Bull Demon King – Fury and Might
The Bull Demon King (牛魔王, Niú Mó Wáng) is a formidable antagonist in the classic Chinese novel Journey to the West. A powerful demon lord and husband to Princess Iron Fan, he rules over the Flame Mountain with immense strength, shape-shifting abilities, and a fearsome iron staff. Known for his fiery temper, unbreakable spirit, and battles against Sun Wukong (the Monkey King), he embodies raw power, resilience, and untamed energy. TANGZU draws inspiration from this legendary figure to infuse the OX Demon King headphones with thunderous dynamics, bold presence, and unstoppable force—turning every track into an epic showdown of sound.
