Crafted With an Ultra-Thin Diaphragm, High-powered Magnetic System, and a Precision Acoustic Design, the i5 Delivers a Truly Likelife Listening Experience

  • Open-back planar magnetic headphones
  • 97mm large driver with ultra-thin 2-micron diaphragm
  • 44 High-strength N50 neodymium magnets for driver efficiency
  • Suede leather headband, walnut wood frame with unique natural grain, and CNC-machined aluminum frame

97mm Large-Diaphragm Driver

The i5 is equipped with a massive 97mm driver and an ultra-thin 2-micron diaphragm, delivering exceptionally low distortion. The expansive surface area enhances resolution, dynamic impact, and transient speed, producing a remarkably natural and immersive listening experience.

Target Sputtering Technology

Utilizing advanced targeted sputtering technology, a highly conductive silver metal voice coil as thin as 1.3μm is precisely coated onto the diaphragm. This process significantly enhances sound refinement while ensuring durability, keeping excellent audio performance consistently stable over time.

Acoustic Mesh

The high-transparency rigid rear mesh structure provides stable air pressure damping and linear feedback. It smooths out frequency spikes and reduces nonlinearity, achieving an open, airy soundstage with ultra-low acoustic resistance. 

High-Strength N50 Neodymium Magnets

Each driver unit features 22 pieces of N50-grade neodymium magnets arranged symmetrically, ensuring precise and stable diaphragm vibration. This design enables accurate and swift dynamic response, effectively reducing nonlinear distortion to produce purer, more natural sound, faithfully reproducing the essence of music. 

Ergonomic Comfort

Breathable, Skin-Friendly Earpads: Soft, ventilated materials reduce pressure and heat buildup, promising long-term comfort.

Dual-Axis Earcup Arms: Allows seamless vertical and horizontal rotation for a custom fit to different head shapes, enhancing both comfort and stability.

Memory Metal Headband: Flexible yet durable, it maintains its shape while adapting to different head sizes for a secure fit.

Stepless Silicone Adjustment: Enables smooth, precise adjustments for a personalized and comfortable wearing experience.
