SE-CH3T Hi-Res In-Ear Headphone


Immersive Hi-Res Audio with a Difference

How can earphones so sleek and slender serve such pure, powerful sound? The answer lies in graphene-coated micro-drivers, rare-earth magnets, and precision-cut aluminum body. The original audio image is aired clearly without vibration. With decades of Japanese audio engineering know-how and the best materials behind the design, bass is deep, fast, and punchy, while detail sparkles into the high frequencies. Enjoy lossless music to the full from your smartphone or digital audio player. Stay connected to receive and end calls using the inline control box. So light you can wear them for hours, the CH3s are the minimalist’s choice for maximum sound.

Graphene-Coated Diaphragm for Hi-Res Audio

Graphene-coated φ 5.5 mm (7/32˝) micro-driver diaphragm suppresses divisional vibration to preserve detail while reproducing expanded Hi-Res Audio bandwidth. Graphene is a diamond-hard, atom-thin planar material enabling wide dynamics and musical expression.

Aluminum Housing and Base

Housing and base are of precision machine-cut aluminum. With better rigidity than resin, there’s less vibration to smear the audio image. Details are crisp with no hint of hardness, and bass is fast, deep, and controlled.

Micro Size for Premium Sound Freedom

Nothing says headphone comfort more than light weight. Small and light in the ear with no pressure, and secure with the right ear-tip size, you can immerse in music for hours with no fatigue, whether you wear conventionally or prefer over-the-ear cable positioning.

Take and End Calls Easily

Accept and end calls from most smartphones using the inline cable remote. It has a single button that activates functions according to number of pushes.

Luxurious Finish and Colour Schemes

The style and feel of the CH3 is unique. Alumite processing gives a brilliant hightexture finish while minimalist styling is all understated class. Subtly coordinated colour-schemes blend with your outfit: the focus is on great sound.

Rare-Earth Magnets for Dynamic Sound

Rare-earth magnets possess strength and power at fractional weight of conventional magnets. This delivers energy for fast dynamic response throughout the frequency range, while adding extra punch to bass notes.
