HiFi Boy OS V3 IEM

One of the first IEMs from a manufacturer that’s still new on the scene, the HiFi Boy OS V3 is getting a lot of love from the audiophile community. It uses a triple-driver configuration with one ultra-high-frequency balanced armature, one high-frequency balanced armature, and one 7-millimeter dynamic driver with a magnetic composite diaphragm. Designed to fit comfortably in most ear shapes, the OS V3 promises superior comfort. And thanks to its 19-ohm impedance, it can be easily driven by portable sources.

In a five-star review, Head-Fi user twister6 says, “This new ‘budget’ IEM from HiFi Boy definitely caught me by surprise with its natural, detailed tonality and impressive low-end extension. I was also very pleased how well it paired up with all of my sources, from lo-fi to summit-fi level, and how well it worked with any genre of music I threw at it. And to top it all off, these also have excellent design ergonomics with a comfortable fit and a great sound isolation.”
