Xiaomi Hybrid (QTER01JY)
Dynamic Driver + Balanced Armature

Xiaomi has surpassed most of my expectations with their new Hybrid earphones. They are excellent. Powerful and warm sound, with enough mid-bass and sub-bass to keep you interested, pretty good mids and highs (even if somewhat muddy when there are acoustic instruments involved) and amazing comfort, especially if you can get some quality foam tips.

Pros
Cons
  • The sound of these earphones is overall great.
  • The build quality and design of these is something to behold.
  • Are extremely comfortable to wear.
  • Vocals and acoustic instruments tend to be slightly muddy because of the bump in the mid-bass.
  • The included tips are quite generic.

Comfort & Fit

Personally I had a hard time keeping a good seal with these earphones, they seem to always come out eventually.

Lows / Bass

The bass on these earphones was significantly improved compared to Xiaomi Piston 3, especially the beefy sub-bass. However, the bass has a slight tendency to leak to the mids and overpower the vocals.

Mids / Vocals

Vocals are slightly blanketed by the bass response and don't sound entirely accurate. They are both darkish and a bit sharp and harsh at the same time.

Highs / Treble

The highs are somewhat in the background, and are relatively dark and unnatural. Occasionally, some piercing cymbals and hi-hats can be experienced, and while they aren't loud, they are still high-pitched and uncomfortable.
