Linsoul Kiwi Ears Quartet 2DD+2BA Hybrid In-Ear Monitor, HiFi Earphones with Hand-crafted Resin Shell, Detachable OFC Silver-plated IEM Cable for Audiophile Musician DJ Studio Gaming (Purple, Quartet)

At Kiwi Ears, we strive to achieve exceptional audio reproduction by combining technological innovations with refined tuning strategies, creating the perfect blend of science and artistry. The name Quartet is inspired by the four high-performance drivers that work together in perfect harmony to deliver an exceptional listening experience. This unique configuration allows for unparalleled clarity and detail across the entire frequency range, while still providing the powerful and impactful bass that the Quartet is known for.
The Kiwi Ears Quartet was designed around our new isobaric double dynamic driver subwoofer. The innovative driver design utilizes double 10mm titanium diaphragms drivers, each independently driven by dual magnetic circuits. The pair of drivers were passively aligned to be phase synced and prevent soundwave cancellation. This new subwoofer design emits extremely well extended sub-bass kicks that are tighter, faster, and deeper than any other previous woofer designs. The Quartet is Kiwi Ears answer for all those who want a fun in-ear monitor that will provide all the quality bass one could need.
Although the Quartet is a bass-centric IEM, we still aimed to provide a natural tonal balance. This goal was centered around the need to provide a textured and powerful bass, but without any muddying or dulling in the mids or treble. The dynamic drivers were crossed over using a passive low-pass network at 350Hz to allow plenty of rich and thick bass, while the mids from 350-1kHz were tuned to be completely flat. This allows an accurate tonality in the mids like that of neutral studio monitors, while giving a hint of warmth in the lower mids.
The Quartet features a custom mid-high frequency balanced armature and a custom ultra-high tweeter balanced armature drivers. These drivers were modified to fit the balance of the new dynamic drivers by a tuned venting system to provide more airflow. Following Kiwi Ears tradition, the balanced armatures are passively tuned to fit our in-house target curvature for the mids and trebles. This means the mid-treble provides crisp and clean tone to vocals and instruments, without sounding either dull or nasally.
