A 2DD+2BA hybrid IEM with an isobaric dual dynamic driver design for extended sub-bass and four tuning-switch configurations.
Official product pageOverview
The Quartet uses two independently-driven 10mm titanium diaphragm dynamic drivers in an isobaric configuration with passive phase-syncing to avoid soundwave cancellation, crossed over to custom balanced armatures at 350Hz for crisp mids and treble. The medical-grade resin shell pairs with a detachable oxygen-free silver-plated copper cable, and four tuning switch configurations let listeners adjust the sound signature.

FAQs
What does isobaric mean in this context?
Two dynamic drivers are independently driven and phase-synced so their soundwaves reinforce rather than cancel each other, which Linsoul markets as boosting sub-bass output.
Can I adjust the sound signature?
Yes — the Quartet includes four tuning switch configurations.
How long does a pre-order take?
Linsoul lists 15-20 working days for CIEM (custom) orders and 10-12 working days for UIEM (universal) orders.
