THE CARBON

The aluminum carrying / storage case is large enough for both the IEM's and the airplane adapter.

Periodic Audio likes to cover the needs of every single consumer out there so once again they've placed 9 pairs of ear tips (dual and single flange medical grade silicone earbuds and foam earbuds all in small, medium and large).

Once again, we find the same 1.5 meter long silicone coated 4-core cable with butyl rubber strain reliefs used in both the Beryllium and Titanium models (although tangle-proof these are unfortunately non-detachable ones so strain concerns do exist).

The bullet design of the polycarbonate polymer bodies is nothing new since to date all of the IEMs produced by Periodic Audio have featured the same (these may not have the same fit as angled models but they are very efficient in terms of acoustics).

Moving at the rear we find the same grade 304 stainless steel caps used in previous models (however black for the Carbon model).

At the top of the polycarbonate polymer body there's a small vent hole.

As with all previous models these IEMs have no left and right markings, instead the grade 316 stainless steel grilles of the nozzles (6mm in diameter) are painted differently (red for right).

The 1.5 meter long silicone cable has a gold plated 3.5mm jack on its end.

For the majority of this review i used the FiiO M11 Music Player (best one right now in the lab) paired with ear tips by SpinFit (used over 100 lossless FLAC tracks for this review).
