Dual dynamic + balanced armature drivers

The all-new mi in-ear headphones pro HD comes with hybrid dual-dynamic and balanced armature drivers. The dual-dynamic driver keeps the bass and mid tones mellow, and is made with graphene material that pumps out sounds with fuller and richer details. The balanced armature driver retains the rich details of the high notes for the main melody, so you get to experience the tri-band equalization effect. Now it feels almost like you're close to nature, with the all-new mi in-ear headphones pro HD.

Tri-band equalization, sounds so beautiful and natural

To achieve a balance in the bass, mid, and high audio ranges, we included dual dynamic and balanced drivers in our all-new mi in-ear headphones pro HD. The larger dynamic driver is responsible for the lower audio ranges, whereas the smaller dynamic driver takes care of the higher audio ranges. When the dual dynamic drivers combine with the armature driver, the sounds produced are resoundingly richer and fuller.

Graphene diaphragm, dual dynamic drivers

Voices and instruments have sounds that reside mostly in the mid and bass ranges. To deliver a superior sound in the mid and bass ranges, we have used a graphene dual-diaphragm to retain the rich details and to keep the low notes mellow.
Graphene is known to be the thinnest, strongest, and most eco-friendly material able to transmit sound fast. We used it to create the diaphragm so it is more ductile under high frequencies, producing sounds that are rich, sharp, and crystal clear. It is 100 times stronger than steel, conducts 100% of the electrical signals passed through them, and accurately delivers sounds the way it was meant to be heard.

The all-new design comes with dynamic drivers and produces superior sound quality and rich details with little distortion

The mi in-ear headphone pro HD uses patented, hybrid dual dynamic and balanced armature drivers that deliver music of greater and finer details. With the help of a capacitive divider, there is higher convergence with the bass, resulting in lesser distortion to the music. So now tuning into music feels like listening to a good story that touches the soul.

Scientific acoustic tuning delivers natural and clean sound that warms the heart

Every piece of music tells a story. To deliver the true representation of the music, we enlisted the help of a 4-time grammy award-winning tuner, Luca binary, to conduct scientific acoustic tuning for our mi in-ear headphones pro HD. Now audiophiles can truly immerse themselves in every single musical creation.

All-new design. Sounds good, looks good

A pair of well-designed headphones shouldn't just sound good, but should also act like an ear accessory.
The mi in-ear headphones pro HD has adopted a rounded and 45° angled in-ear design to fit perfectly and deliver true music to your ears. It has precise cavity structure calibrations that let music sing better.
It also comes with highly stretchable TPE wiring that is hardy and durable.

45° angled in-ear design, ergonomically designed for comfort

The mi in-ear headphones Pro HD are ergonomically designed to conform to the shape of your ear canal. The 45° angled in-ear design fits snugly and closes off to environmental noise, so you can enjoy pure music without much external interference.

Full metal wired control feels great on your fingertips

The mi in-ear headphones Pro HD wired control is inspired by the overall design of the headphones. It is dressed in full metal and lined with highly stretchable matte wiring, making it sleek, and compact, and feels great on your fingertips.

Stretchable matte wiring wires you up on long music journeys

We've specially selected TPE, with elasticity similar to that of rubber, as the raw material. It is environmental-friendly, non-toxic, and heat-resistant. Now you have quality headphones that are durable, dirt-resistant, and have tangle-resistant wires to accompany you on longer music journeys.

Soft and comfortable earbuds sit perfectly on the contours of your ear

To reduce the risks of developing ear skin irritation, we've specially picked a medical-grade silicone that is delicate, soft, and gentle on your skin. We have also provided 4 different pairs of earbud sizes for you to find the perfect fit. Now with the mi in-ear headphones Pro HD, you have that perfect acoustic companion to accompany you all day long.

Every step ensures great music gets delivered

Creating the metal sound chamber is a 25-step process that involves integrated diamond cutting, cd engraving, zircon sand blasting, and anodizing. Every step is meticulous and of the highest precision, presenting you with a final piece of artwork that excels in both design and sound quality.

CNC diamond cut technology for a delicate feel

The aluminum alloy iron sound chamber is crafted with a CNC diamond cut finish with up to 0.01mm precision. Such a crafting process requires prior analysis of the aluminum material before it is sent for processing, resulting in a pair of mi in-ear headphones pro HD that is comfortable and delicate on the ears.

Detailed cd pattern, additional brilliant texture to the metallic body

Mi in-ear headphones pro HD include a fine, detailed 0.14mm grain that adds a textured metallic luster similar to cd discs on the headphone metal body.

Zircon sand blasting and anodizing layer to protect against wear and tear

We've specially picked the zircon sand as the raw material to give our mi in-ear headphones Pro HD a fine, uniform finish. This also ensures the surface is hardy and resistant to scratches. Before it gets shipped, we've also dressed the headphones with an anodized layer of 6μ hardness to enhance their appearance, on top of protecting against wear and tear.
