Introduction: 

Zalman has made quite a name for themselves in the cooling market, and they are arguably one of the top manufacturers. But Zalman has also ventured into other markets, and have released a few audio products, one of which is the Zalman ZM-DS4F headphones, which we are going to be taking a look at today.

These headphones are very competitively priced and are aimed at the MP3/CD/Music crowd, let's see how they perform. These headphones feature a 2-way 4 speaker system, and feature two independent speakers in each ear cup.

 

First Impressions:

I was pretty interested to give these headphones a try, as 90% of the time that I am using my computer I'm using headphones since my neighbors do not share my enjoyment of music at late hours.

Pulling them out of the box makes you immediately notice that they are really foldable, but once you get them on your head they are quite comfortable unlike some other folding headphones I've used in the past.

In the above pictures you can see that these headphones fold down and become nice and compact, which is a feature geared towards the portable media user. The ear cups pivot which helps make things more compact when folded, but also make the headphones pretty comfortable as they adjust nicely to your head.

Note that the picture below shows that these headphones feature 2 speakers in each side. Zalman has a great diagram how that all works as you can see below. The idea behind the dual speakers is to be able to produce greater sound than other single speaker systems can.
