Koss Spark Plug (159724)

The American company Koss has been proving for many years that it knows a lot about not only good sound, but also how to sell it. One of the proofs of this is the legendary model of Spark Plug headphones.

Originality

The design seems funny at first glance. Headphones resemble floats and look somewhat bulky. But upon closer examination, it becomes clear that everything is in its place and thought out to the smallest detail. Seemingly uncomfortable and rough, the ear cushions are made of soft polyurethane memory foam, so they sit perfectly in the ear and do not tyre. But in extreme cold, they harden and lose their elasticity.

Power

Soundproofing is almost complete. In addition, the sensitivity of 112 dB provides the radiators with a large output power. Therefore, the manufacturer thought out holes on the outer part of the case to remove excess sound pressure at a high volume level. The level itself is conveniently changed using the volume control on the cable.

The driver provides a powerful, accented sound at all frequencies, but the bass component is brought to the fore and is clearly audible under any conditions.

Reliability

Despite the impressive appearance, the model weighs just over 10 g, and has cable protection against bending at the junction with the plug and emitters. However it helps a little. The cable looks too thin, so it still doesn't hurt to protect it from breakage and fractures.

Spark Plug is offered by the manufacturer for only 20 USD. For the money, the best wired in-ear headphones simply cannot be found.
