KZ ZS5
Ø10mm + Ø6.4mm Dynamic Drivers + 2 x B.A.

KZ has become a serious brand, and their latest ZS5's sound quality absolutely blows away most of the earphones on AudioBudget, if not all of them. They have deep bass, yet aren't boomy. The mids and highs are not ressesed at all and are highly detailed.

My only complains would be the design (especially from a comfort standpoint), the materials used for the housing, and the included cable, which is very basic but better than the common gut-looking cable KZ have been using. However, for a small extra fee, you can get yourself a much better cable.

Putting it short, these are one of those earphones you just must have!

Comfort & Fit

I would admit that these aren't the most comfortable ones, as their shape has nothing ergonomic about it, it's blocky and has sharp edges. Putting them inside the ears isn't straightforward and takes some getting used to.

Lows / Bass

I was expecting these earphones to be "Hi-Fi-oriented", in essence missing any bass. I was pleasantly suprised to be completely wrong. The bass is powerful and very deep, will satisfy even the most extreme bass-maniacs. The bass doesn't leak into the mids at all, almost as if the bass is completely separate from anything above low frequencies. These earphones' configuration was indeed well designed.

Mids / Vocals

The mids are highly impressive, considering the fact that neither the lows nor the highs were sacrificed in the process of designing these earphones. The vocals are clear and upfront, emphasized but not exaggerated. Instruments are properly separated, even though the soundstage doesn't seem to be exceptionally large. Because of the emphasis in the upper-mids/lower-highs, there seem to be some instances of sibilance, so keep the volume level adequate to avoid any unwanted piercing notes. These earphones will excel at any genre you'll throw at them!

Highs / Treble

Might seem just a bit too bright in the beginning, but after a few minutes of hearing adjustment, the highs become bright and delicate, with high emphasis on brilliance and detail. Some well-tuned peaks in the upper-highs are responsible for those pleasant high-pitched notes you can hear in the background. I was listening to all kinds of music with these earphones for hours and I felt no hearing fatigue.
