KZ S1 and KZ S1D Have The Same Design
KZ S1 and KZ S1D have in-ear design like most other wireless earbuds. However, as we already said, they have a unique and unusual design.
By the way, both models of wireless earbuds have the same design. The only difference in design is color: KZ S1 comes in gray and dark green, while KZ S1D is available in white and black.
Replaceable ear tips are transparent, regardless of the color of earbuds.
The earphones and charging case is made of ABS plastic.
KZ S1 and KZ S1D are truly compact earbuds. The weight of the charging case is only 50 grams, while one earbud weighs about 4 grams. They are very light and almost not felt out of the ears.
The entire front side of earbud is a touch control panel. As we said earlier, the recognizable KZ logo is located on touch button.
On the inside of the earbud are magnetic contacts for charging, a built-in microphone and an LED indicator.
The charging case is also compact. It is very convenient to carry the case in a hand, or in jeans pocket. It has an oval shape.
On the back of the charging case is a USB port for charging.
Earbuds are securely attached inside the charging case. We can also see a small LED indicator and round button inside the charging case.
The button is used to check the battery level. Depending on the battery level, the indicator light is highlighted in red, yellow or green.
What’s The Difference Between KZ S1 vs KZ S1D?
Now let’s move on to the technical specifications of the new earbuds. First, we want to tell you about differences between the two models of wireless earbuds, and then let’s talk about the general specs.
KZ S1 and KZ S1D have only one difference in technical part. KZ S1 are more powerful because of the built-in high-frequency balanced unit and lightweight REK membrane. The high-frequency unit makes the sound richer, while musical instruments sound more natural and clear.
The small, thin REK membrane releases full mid and low frequencies.
KZ S1D are equipped with only a thin membrane REK without built-in high-frequency balanced unit.
As you understand, KZ S1 earbud offer a more powerful, rich and clear sound than KZ S1D. However, we are not sure if the average user will notice a significant difference.
Otherwise, KZ S1 and KZ S1D wireless earbuds have exactly the same specifications.
KZ S1 and KZ S1D Have Almost The Same Features
