Emotive detail in-between layers of a song are often lost when you use headphones with either a dynamic or balanced armature driver. In attempt to create a more precise listening experience, we placed two drivers into one single set of headphones. This produces a sound clarity across a wider audio range. Bass and mid tones are kept mellow with a dynamic driver, perfect for bringing out the drums and bass. Yet high notes for the main melody retain rich detail with a balanced armature driver. It's time to rediscover the nuances in your favorite song, just plug in Mi In-Ear Headphones Pro.

The patented balanced armature driver produces greater fidelity even for faint, high notes in a song. It has been redesigned with a higher sensitivity, better transient reponse and lower distortion for high frequency sounds. Independently researched and developed, we used high precision assembly techniques to create a lighter, more compact balanced armature driver. The drive rod is solder-attached to the driver for a studier structure and steadier sound. We also added a capacitive divider to allow the driver to operate naturally, connecting high, mid and bass notes. The balanced armature driver enhances your music's expressive power so high notes are enchantingly clear and drum beats blend better into the music. Rediscover the little details in your favorite music, like the breathing techniques of singers as they take their next breath.

Voices and instruments have sounds that reside mostly in the mid and bass ranges. In order to deliver a superior sound in the mid and bass ranges, we sandwiched³ an aerospace-grade metal composite layer inbetween two PET layers. This preserves the outstanding treble responses of metal, while improving richness in the lower ranges thanks to the incredible flexibility of PET. This breakthrough design in Mi In-Ear Headphones Pro provides balanced output and superior definition across the entire frequency range.

A good set of headphones bridges composers and their listeners. To produce an exceptional acoustic tuning, we used various scientific tuning and calibration methods such as the Klippel high-speed scanning vibrometer system. The Klippel system simulates recordings with a dummy head to identify the most ideal acoustics. Improvements are then made to the headphones structure based on the data received.

Features metallic elements like in previous Mi In-Ear Headphones. Creating the metal sound chamber is a 20-step process that involves diamond cutting, CD engraving, drawing and anodising a piece on aluminum. It is resistant to wear and discoloration even with prolonged use. Its ergonomic curves have been carefully conceptualized for utmost comfort, while looking polished and trendy.
