We were lucky enough to be sent three out of the four headphones Periodic Audio has to offer: the Magnesium, Titanium, Beryllium as well as the Nickel. This young company wants to create the best audio experience by stripping away all the bulk and unnecessary frills and focusing on a high quality sound in a super portable way. Periodic Audio is a company formed to act as the self-funded, small team of audio product specialists, who want to produce “performance heavy, and buzzword-y feature impaired”, devices.
