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.
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.
C5’s snug fit and stunningly realistic sound means you can forget the rest of the world and lose yourself in music. At the same time, these in-ear headphones let in just enough ambient noise to allow you to retain your sense of place. Perfect for listening to music when you’re out and about.
