Arctic Cooling E352 Earphones - Technical Overview

Technical Overview


Speaking technically, let's start by looking at some specifications.


Output power: 15mW (micro watts)


Speaker dimension: N/A


Impedance: 32 ohm


Sensitivity: 104 db/mW


Cable length: 1.3m with 3.5mm stereo plug


Jack: stereo mini: Yes


Microphone: No


Frequency response: 18hz-22khz


Impedance: N/A


Pick-up pattern: N/A


Sensitivity: N/A


Since the last pair I looked at things have not changed a whole lot. Output power stays the same, as does impendence, cable length and connection type. However, we do see a change to the frequency's response with a lower, or as I like to call it, more accurate rating of 18Hz - 22KHz.


Gold plating is used on the plugs for the highest signal quality between devices connecting to one another. Also featured is compatibility with several of the large mobile phone brands out there. And finally, a two-year warranty, which is a nice touch, I feel.




The most notable change here is of course the wooden chassis used instead of the aluminum one. However, I cannot see any specific information regarding the choice to use wood other than 'warm sound definition by exquisite wooden chassis'. So, clearly Arctic Sound thought they were onto a winner, but equally did not want to give too much away.


Generally in the construction of a wide range of loud speakers, wood or more especially medium density fiberboard (MDF) is thought to be best. This is then covered by a thin veneer of the wood that serves an aesthetic purpose for the final outer layer.




Frequency reproduction whilst certainly toned down from the last model I tested, is still quite an optimistic figure to behold coming in at 22KHz, at the high end.


Like the previous model, the E352's are quite light to hold and should not require a football players neck structure to be enjoyed. Even when considering that wood has been used in their construction, the weight does not increase from the feather-like 5 grams.
