Zalman ZM-DS4F Headphone Review
Reviewed by Falcon
Special thanks to the folks at Zalman for providing the evaluation unit.
Zalman is a company that is well
known to gamers for their aftermarket PC and chipset cooling devices. Recently
they have made the foray into headphone sets, and today I will be taking a look at
one of their latest innovations - the ZM-DS4F.
The ZM-DS4F is an ultra-portable headphone designed for use
with portable music players. It packs an impressive set of specifications
including a 4 micro-speaker system (a 28mm tweeter and a 40mm PEI woofer for each channel) into cups that
are the size of your ears!

First looks:
As you can see from the pictures, the headphones come
packaged in a compact, folded shape that is designed to save space for easy
transportation. The box is loaded with an array of features and specifications
of what to expect inside the package, and the diagram of the speaker system
shows the 28mm tweeter positioned directly in front of the 40mm woofer inside
the cup. Having dedicated low and high range outputs should allow for better
sound reproduction and clarity on the high and low sound ranges.
The design is not too flashy, but still looks pretty cool. The
parts are predominantly made of plastic, with some covered foam padding on the
inside of the cups and below the top of the headband. Due to the fact that they
were designed to be foldable and lightweight, these headphones do not boast a
very solid feel. However the parts appear to be durable enough to withstand the
rigors of daily use and transportation.
The length of the headpiece is adjustable, and the cups come
in a toe-in design that pivots to comfortably sit over the ears. The cups are
around 5cm (2”) in diameter, meaning that they will rest on the ears rather
than over them. The lightweight nature of the headphones, and the ability of
the cups to pivot makes this possible without causing any discomfort. I found
the feeling a bit strange initially, but quickly got used to the positioning.
Onto the testing and conclusion:
