Mi In-Ear Headphones Pro HD specifications, design, and features
The Xiaomi Mi In-Ear Headphones Pro HD is, as its name suggests, a pair of in-ear wired headphones. The frequency response range of 20Hz - 40,000Hz is quite good and should be able to translate into good audio performance. You get hybrid dual-dynamic and balanced armature drivers, with the dual-dynamic ones responsible for the bass and mids, while balanced armature ones deliver the high frequencies. Xiaomi has used graphene diaphragms which, it claims, deliver richer and fuller sound.
Mi In-Ear Headphones Pro HD performance
For testing the Xiaomi Mi In-Ear Headphones Pro HD, we used a OnePlus 5 and an Asus Xonar U7 external DAC. We chose a wide variety of mediums including Google Play Music streams and MP3s and FLAC files. We used Carry Me by Kygo, Locked out of Heaven by Bruno Mars, and Back in Black by AC/DC as our focus tracks.
We found that the Mi In-Ear Headphones Pro HD needed a bit of a burn-in before they started sounding good. We found four pairs of ear tips in the box but found them all to be flimsy, and had a hard time getting a proper seal even with the largest size. A direct result of this was a drop in the quality of the bass. When listening to Carry Me by Kygo, the bass pattern was hard to discern. Even at the highest volume, we found it to be too low for our liking. We plugged the headphones into the Xonar U7 expecting that the DAC would help with bass delivery, but that wasn’t the case. It might be that these headphones are tuned to deliver mids and highs while holding back on the bass
Priced at Rs 1,999, the Xiaomi Mi In-Ear Headphones Pro HD is positioned as a pair of premium headphones for a superior audio experience. However, we found that the sound lacked bass even though mids and highs were delivered well. Using Comply eartips did improve the experience, but these will bump your budget up by a few hundred rupees, and it shouldn't be necessary to buy something else to make this product work. Instead we would recommend the OnePlus Bullets V2, which offer better bass and a fuller sound while saving you money.
