Idea of Source Four Par Icon
It's a logo for Source Four Par that looks like a microphone on a business card. It's a cylinder protruding from a rectangle, the cylinder's surface has a squared net over it.
This is a Source Four Par icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
