Bass & Sub Bass
The KZ BTE bass is powerful and punchy with an energetic tuning style. Mid bass might fall into a bouncy style and sub-bass, despite being deep, might not get as profound as on other KZ models.
Nonetheless, their lower frequencies are tuned for a fun and rich bass listening experience where most intense bass track’s requirements will be fulfilled by the KZ BTE.
Applying an EQ, there is a intense enhancement of both mid-bass punch and sub-bass depth.
The difference between the “Normal” mode and the “Shocking Bass” mode is not drastic, it is mainly a very strong increment of volume output and some boosting of it’s bass.

Mids & Vocals
The KZ BTE mids have very crisp higher mids that can become almost forward. Lower mids and male vocals are somewhat distant and laid back, despite a mid-bass bleed intensity not too invasive.
The upper end of their midrange can get frequently harsh with strong peaks.
With an EQ, their lower vocals can be cleared up and higher mids slightly smoothed. Still, both will conserve their original tuning style.
Highs & Treble
The KZ BTE highs resolve an, unexpectedly, good quantity of detail and offer a fair amount of brightness but there is a slight darkish tint that can be felt over them.
Some piercing peaks and sibilance can arise, tending to become too intense from time to time.
An EQ makes their highs better balanced between brightness and detail but also much more fatiguing.
The sound leaking out of the KZ BTE is mildly less hearable than on many other average earphones. Still, their sound will, certainly, be heard by nearby people once the volume get’s above moderate.

The sound isolation provided by the KZ BTE is noticeably above average with an immediate partial isolation, even with no music and a near-absolute level by just dialing up the volume a bit.

This less-standard shape is usually marvelously comfortable to some people and not so much to others – it mainly depends on each user. In general, all of our editors did not find much to complain about the fit and comfort of the KZ BTE.
A clear advantage of the housing’s shape of the KZ BTE is the firm fit that can withhold even the most intense activities without needing any “wings” accessories.

Response to Equalization
The response to EQ was very noticeable over lower frequencies but not as efficient on mids and highs.
