Periodic Audio C (Carbon) IEM and Ni (Nickel) Headphone Amp In The House!-First Impressions And Unboxing Pics

Just got a pair of Periodic Audio’s new Flagship in-ear headphones, the $399 C (Carbon) IEM in the house, and I can’t wait to give these a real good listen. Periodic Audio basically only makes IEMs, (they do have the Nickel amp, which I also have) and their mission is to make the best sounding one on the market.  They approach this in a novel way by utilizing pretty much the same housings, tips, and cables for all of their models, then installing a single wideband driver of increasingly stiffer materials as you move up the line.

In the case of the Carbon, they coat the driver with diamond, which is supposed to give you the most detailed sound with the least distortion. So far I can say they have a very punchy, forward, resolving sound, these are no shrinking violets.

I also got ahold of the $299 Ni (Nickel) Portable Headphone Amp, which is pretty powerful for its relatively small size. Stay tuned for my full review!
