Frequency Response

Frequency response is the range of frequency headphones can produce, where the lower limit is the bass sound and the upper limit is treble. The human ear can only hear frequencies ranging from 20-20,000Hz, so most headphones try to stick to this range. However, some headphones extend the range at both ends to provide deeper responses. If you like more bass, then opt for something that can support wider than the usual frequency response range.

Impedance

The impedance of a headphone represents the amount of power needed to drive a pair of headphones. Low-impedance headphones require less power to drive, and can therefore easily be used with source devices with weaker amplification, such as smartphones, media players, and other portable devices. On the contrary, high-impedance headphones require dedicated amplifiers or increased amplification to drive and deliver a more powerful, driven performance as a result. When choosing headphones, it’s important to note the impedance and buy according to the source device you intend to use. Look out for the impedance figure on the box, and choose as per your source devices. The impedance of 15 Ω (Ohm) and under is low and easy to drive.

Soundstaging and Imaging

It represents the ability of headphones to create an accurate sonic stage and image within your mind. Good sound staging and imaging will create the impression of a live performance, where individual elements of the sound are distinct and feel like they are originating from specific locations on the virtual stage. Separation of sonic elements is also a function of imaging, where better separation represents a more realistic, true-to-life sound. This is best judged by listening and keeping your ears open for separation and clarity, so you won’t find it on the specifications of the headphones, but you’ll often see it mentioned in reviews.
