Aerospace-grade metal diaphragm with a patented "sandwich" design

Excellent sound quality begins with the diaphragm, which is embedded at the heart of any headphone. In order to deliver a superior sound in the mid and bass ranges, we sandwiched 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 has revolutionized Mi In-ear Headphones, providing balanced output and superior definition across the entire frequency range.

Optimized front cavity for improved treble performance

The 3rd gen balanced damping improves airflow to delivers proportioned outflows for the front and back chambers. Combined with built-in damping material, Mi In-ear Headphones produces vivid stereo effects and a transparent, wall-balanced sound. The metal composite diaphragm speakers are allowed to operate naturally to deliver a high-fidelity experience. In addition, a separate output channel and output hole in the front cavity provide better balance and treble performance.

Patented technology to fully optimize mid-range and bass output

To optimize mid-range and bass performance, we modified the classic transmission line enclosure design with a patented sound chamber that incorporates spiral air-flow channels and extended bass output sound holes. The benefits of these longer sound output channels can be heard in improved sound quality and stereo effects in the mid and bass ranges.

Meticulous calculations for an extremely precise sound

We use a variety of methods to deliver the best possible sound within the limits of a confined space. First, we calculate the ideal dimensions for the diaphragm and cavity using specialist software. Then we monitor the state of the diaphragm using a Scanning Vibrometer System to find the perfect sound. Audio output from the headphones is analyzed using SoundCheck software, including parameters such as frequency response and total harmonic distortion. Listening tests are also conducted by audio experts and musical specialists, combining objective measurements with a sophisticated ear to achieve the highest possible quality.

Lower distortion, more detail

Mi In-ear Headphones outperform the Sennheiser CX985 and Urbeats on the distortion curve. This means that you can hear much more detail and experience less distortion.

Excellent audio quality, low interference and distortion

The built-in Knowles MEMS microphone provides excellent stability despite its tiny size. The wire control provides a direct, solder-free connection to ensure maximum clarity with minimum interference. It is fully compatible with Mi phones and partially compatible with iOS devices (volume up/down functions not supported).

Strong, break-resistant kevlar fibers protect wiring and extend its lifespan, while braided sleeving prevents tangling. The end sections are sheathed in TPE to reduce friction with clothing, preventing an annoying “stethoscope effect” or noise interference.

Tested by hundreds of users

Usability is a top priority in our design process. In order to create an ergonomic design for maximum comfort, we drew on a vast set of data and test designs with hundreds of actual users to find the most ideal dimensions.

Corrosion resistance and long-lasting wear

Brushed aluminum at the back of the headphones create a sleek profile. The metal surface is anodized to protect against corrosion and wear, and is subject to stringent testing to ensure minimal peeling even after extended use.

Includes cable winder and 3 earbud sizes

Mi in-ear Headphones come in a stylish, eco-friendly package. The silicone earbuds come in 3 different sizes (XS/S/L) to fit your unique needs. Comes with a cable winder for convenient storage.
