In terms of extra features, there is the world's smallest mic which I feel should be adequate for capturing the buyer's screams of 'mercy' as 'frag-a-lot' knocks you down for the one billionth time in COD.
The other nice feature is the inserts for your ears, which also allowed me to determine that by Swiss units of measurement, I have large ears.
The E361-WM is great little audio solution that packs a plethora of surprises into its diminutive stature.
I'm not too sure how much the Arctic Sound E361-WM will sell for; in fact, I cannot even find any articles on them currently, so I must have a pre-pre release sample. Either way, though, I can see them being good value even up to a hypothetical AUS $80-90, which is a LOT for earphones.
The audio quality, as I have mentioned earlier, is really impressive the moment you put them in to your ears. There really is not a whole lot to fault about their performance during testing. At no point did I feel a trickle of blood running down my ear lobe to indicate a tortured ear as has been the case before.
Rather, I could only feel the hairs on my neck bristle with delight at being awakened by the dulcet tones I was hearing.
My advice is when these get shipped to the public, grab a set and when you need a secondary option to your loud speakers; slip them in and enjoy.
