Koss KSC-55 Specifications, Tests and Review

The Koss KSC-55 are wired headphones. In the case of studio and professional DJ headphones, a wired connection is a standard and a necessity. In this case, connecting via cable reduces audio transmission delays and prevents unwanted battery drain as it would be in case of wireless headphones. The same is de facto true for gaming headsets. In case of headphones for normal music listening, the cable is rather a relic, although it still has its fans. However, the wireless option is much more popular for everyday use in today’s world.

The sound quality can be affected by many factors. The Koss KSC-55 reaches the sensitivity values of 101 dB/mW. The sensitivity of the headphones expresses the ability of the headphones to pick up the signal from the source and reproduce it with sufficient volume. The higher the sensitivity, the more easily the signal is converted to sound and the louder the headphones are able to play at a lower power consumption. It is important to remember that high listening volume can consume more energy from connected devices. So if you want to listen to music from your cell phone, it's better to choose headphones with low sensitivity to avoid draining your phone's battery too much. Headphones with a lower sensitivity value (around 85 dB) are better suited for listening in quiet environments, while medium values (around 90 dB) allow for quality listening in noisy environments such as public transport or cafes. Headphones with a high sensitivity value (100 dB or more) are designed for use in really noisy environments such as concerts
