    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!

    Technical Specifications:Zalman - Box

    Unit Type

    4x Electro Dynamic round type micro speakers

    Frequency Response

    Sound Pressure Level

    103dB +/- 3dB

    124g (without cord)




    1 standard 3.5mm stereo headphone jack


    $29.95 USD

    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.

    Box Side

    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.
