Sound of the KZ ZS4
The KZ ZS4 are the successors to the ZS3. Although they are very similar, the ZS4 has a new multi-driver configuration instead of a dynamic driver (ZS3). In addition, the ZS4 is one of the only earbuds with a rubber cable.
Our KZ earbuds come standard with the supplied cable without a microphone. Of course, it is very convenient to have a microphone and remote control, which is why these can be ordered as an option.
Are you looking for a spare cable or do you want to upgrade the supplied cable? Then take a look here.
Also, these earbuds can be used wirelessly through an optional Bluetooth cable. These can be found here.
KZ's specialty is producing earbuds with great sound, at a reasonable price. Even many Audiophiles are enamored with KZ, something previously unthinkable for a Chinese brand. This is because KZ Audio does not put unnecessary money into producing fancy packaging or fancy advertisements. This is reflected in the use of the durable materials and therefore in the sound quality. Chinese HiFi (ChiFi) is on the rise, and as far as we are concerned KZ Audio is largely responsible for this. Experience the sound quality of the KZ earphones for yourself!
Another big advantage of KZ Audio is that the earbuds come with a detachable cable with an A, B or C plug.
Often earbuds break down because the wire wears out too quickly. Therefore, KZ Audio not only makes the earbuds much more durable here, but also shows what it is all about: good earbuds at a reasonable price. And not to produce earplugs that will break anyway!
In addition, the cables supplied are nicely braided and therefore very strong. It gives little noise when it moves and is difficult to get tangled.
Also, the wire is extra sturdy around the end. You can easily rest it behind your ear, making it more fine and firm. This keeps the earbuds from falling out of your ears as quickly and provides extra comfort.
