Overview

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.

Pros

Isobaric dual 10mm dynamic driver design for extended sub-bass without cancellation
Four tuning-switch configurations for an adjustable sound signature
Detachable silver-plated cable
Budget-friendly for a 2DD+2BA hybrid design

Cons

Bass-forward isobaric tuning may not suit listeners wanting a flatter, neutral signature
Price varies up to $309 depending on the configuration option chosen at checkout

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.
