Design
The HD 600 circumaural is made of plastic and has the nineties feel with its steel blue marble exterior.

This allows for a clear and transparent sound. The external grilles are easy to replace, even though they can be bent under pressure.
A neodymium-ferrous magnet is used by the driver to enhance sound sensitivity and provide a dynamic bass response.
The HD 600 employs a duopoly 2-layer diaphragm that minimizes sound distortion.
This technology reduces standing waves and lowers surface-born resonance.
The lead cable connects to the headphone and has detachable, rigid plugs at each earpiece.
Three meters long is the detachable oxygen-free copper wire.
These cables are better than coiled cables because there is less chance they will get tangled.
Sound quality
Sennheiser says HD 600 produces “exceptionally natural sound, which is both spatial and precise.”
These headphones are far more powerful than ordinary headphones with a 50-ohm impedance.
Your headphones will be able to handle greater levels of amplification.

You should remember that the sub-bass does not exist. If you require more bass, you may need to purchase a subwoofer.

High-quality amplifiers are required to achieve the best result. The performance of your headphone might not be exceptional if it is plugged into your phone.
