C5 earbud headphones in black

Natural sound

Whatever we make, the goal is the same: the most natural, realistic sound possible. With C5, you can take true sound with you wherever you go. C5 is a mixture of long-held acoustic principles and technological advances, key among which is the Micro Porous Filter. This acts as a diffuser, enabling C5 to deliver pristine, natural audio, while also providing a more spacious performance than previously possible from in-ear headphones. Together with C5’s noise-isolating design, this allows users to lose themselves in flawless audio.

Micro Porous Filter

If you want a spacious sound, you need room to breathe. Not a problem for a large speaker, but quite a challenge for a set of headphones small enough to fit in your ears. With C5 in-ear headphones, we got around the problem with our Micro Porous Filter. Hundreds of microscopic steel balls act as a sonic diffuser, opening up the sound and making music feel remarkably rich and expansive.
