[Excellent Bass Expression] Kiwi Ears Quartet's bass driver uses a new coaxial dual dynamic diaphragm design. The innovative driver design features dual 10mm titanium diaphragm dynamic drivers, all driven by independent dual magnetic flux. This is because this dual dynamic diaphragm is passive and supports phase synchronization to avoid sound waves canceling each other out. This new subwoofer design delivers a tighter, faster and deeper sub-bass kick than any previous woofer design. The Quartet is Kiwi Ear's answer for anyone looking for a fun in-ear monitor, offering all the quality bass you need.
[Natural Sound] Kiwi Ears Quartet inherits the natural and balanced tuning characteristics of Kiwi Ears. To meet the demands of professional musicians and audio engineers, the Kiwi Ears Quartet's sound quality is now similar to recording room ear monitors. Kiwi Ears Quartet adopts a 3-way structure to achieve complex separation, effectively reducing THD+N. Kiwi Ears Quartet's bass is now limited to the sub-bass frequency range. The peak value from 20Hz to 200Hz is 8dB. From 200Hz to 800Hz, there is only 1dB of distortion. The treble already matches the contour of the human ear, with a peak value of 7dB at 2.5KHz, and slowly decays from 10KHz. This precise process allows us to recreate every detail. The sound tube of this earphone is manufactured to international standards and is compatible with most earpieces.
[Customized Balanced Armature Driver] Quartet is equipped with a custom mid-high frequency balanced armature driver and a custom ultra-high frequency tweeter balanced armature driver. These drivers have been modified to match the new dynamic driver balance with a vent system tuned to provide more airflow. In keeping with Kiwi Ears tradition, the balanced armature is passively tuned to match our target curvature in the midrange and treble. Because of this, the midrange provides a crisp, clean tone without making vocals or instruments sound dull or nasal. The high frequency range is detailed and brilliant enough to withstand professional performance, yet it has a natural sound without any sense of harshness or fatigue.
Below is a brief explanation of some issues with Kiwi Ears Quartet headphones. If the pins on your headset are loose, use tweezers to adjust them slightly toward the center so that they are more firmly set and less likely to fall out. If there are bubbles or other problems on the headset panel or other places, please contact us first. Additionally, if the accessories are damaged, we will immediately arrange for the original headset accessories to be sent to you. Additionally, if the paddles of your headphones are damaged or there is a deviation in the sound, we will arrange for a replacement with a new product. At Kiwi Ears Quartet Headphones, we strive every day to provide our customers with a comfortable musical journey!
