Overview

The Timeless uses a 14.2mm planar magnetic driver with a double-sided N52 magnet array and an ultra-thin diaphragm, housed in a CNC-machined aviation-grade aluminum shell with hard oxidation treatment. The detachable MMCX cable has a single-crystal copper inner core, and terminations are available in 3.5mm, 4.4mm, or 2.5mm.

Pros

14.2mm planar magnetic driver with an ultra-thin diaphragm for fast, detailed transient response
CNC-machined aviation-grade aluminum shell
Detachable MMCX cable with a single-crystal copper inner core
Wide 5Hz-40kHz frequency response typical of planar drivers

Cons

Planar drivers are generally harder to drive than dynamic/BA designs, despite the 14.8Ω rated impedance
MMCX connectors are less durable over repeated cable swaps than 2-pin designs

FAQs

What makes a planar driver different from a dynamic driver?

Planar magnetic drivers use an ultra-thin diaphragm driven across its whole surface, which Linsoul markets as delivering faster transient response than a typical dynamic driver of similar size.
