Hybrid 2DD + 2BA Driver Configuration

KEFINE Quatio combines two dynamic drivers with two balanced armature drivers in each earpiece, delivering a warm, lush, and musical presentation. The exclusive 10 mm DLC diaphragm driver handles the full frequency range with high-resolution clarity, while the 8 mm PU + LCP diaphragm driver strengthens bass impact for a fuller low end. The dual balanced armatures kick in above 5 kHz to extend treble smoothly and reveal fine detail and spacious imaging.

Accurate Sound Control

By directing bass, mids, and highs through separate acoustic tubes—10 mm dynamic, 8 mm dynamic, and BA units—Quatio achieves precise frequency division. This hybrid approach, paired with electronic crossover tuning, ensures punchy lows, warm and lush mids, and smooth, non-harsh highs for a balanced overall signature.

Custom Stainless-Steel Tuning Nozzles

Quatio ships with three pairs of threaded stainless-steel nozzles to suit different tastes:
Silver: neutral balance
Gold: transparent clarity
Black: warm emphasis
Easy to swap, these nozzles let you tailor the tonal balance, prevent tube blockages, and extend the product’s lifespan.

Precision CNC-Machined Housing

Each Quatio shell is crafted from aviation-grade aluminum via five-axis CNC machining (30+ minutes per pair, ±0.01 mm tolerance). The polished, anodized metal casing is slim (0.06 mm wall thickness) for a lightweight, comfortable fit, while offering excellent durability and a premium texture.

Modular Plug System

Two interchangeable plugs—3.5 mm single-ended and 4.4 mm balanced—ensure broad compatibility, from professional audio players to smartphones and laptops, without adapters.

High-Purity Silver-Plated Braided Cable

The included 4-strand, silver-plated oxygen-free copper cable (98 strands per core, 392 total) provides lossless signal transfer. Copper warmth merges with silver’s extended highs, yielding a full, detailed sound.

Detachable 0.78 mm 2-Pin Cable

Quatio’s standard 0.78 mm two-pin connection supports aftermarket cables, letting you upgrade or replace cables to unlock new performance or prolong lifespan.
