I took a bit of a break before I decided to write this part of the review, as I was torn as what to say. In the end, I think there just isn't enough going on to warrant anyone to really ponder purchasing this product over any other offering out there. Scratch that, there is one reason, louder sound from the M6 than from my laptop, but it was nothing nice to hear - let me take this a bit deeper for you. The cooling portion of this M6 did allow for my laptop to run two degrees cooler than without it, but so does lifting the back of my Lenovo with a brick. It really is too bad too, because I really liked the looks and feature set when I looked at this online, then in my hands as I took images and looked at what was being offered.
That was until I plugged in the 3.5mm audio cable and found that the speakers sounded worse than anything I have ever owned in the last decade that could produce sounds. What started out sounding like I turned Pandora on my phone and set the phone in a cardboard box with a tiny hole to listen through (it really is that bad), even after days of playing music to break them in, the speakers never got any better. The only two things I can say that were good here is that the fan is silent and does not overstep the audio at any level, and the second it you do get a 10dB increase of sound levels without the need for a driver just by plugging in the cable.
At a price near $40, I really think most buyers would be better off with a cheap pair of headphones with something like 30mm drivers. Even with cheap cans, you are going to get cleaner sound, better bass response, and a more full sound stage in general than you do with the M6. Not including the power cable is just silly to me as well. So, if I were to go portable, now I have audio and a fan drawing from my already short battery life of the laptop.
The 4-port USB hub is nice, the styling is nice, but if you are in the market for a laptop cooler with an audio solution built into it, if you like your ears at all, I think you should wait to see what else shows up in the future, or just grab a brick and some headphones and be happy for now. DEEPCOOL needs to go back to the drawing board with its next product in this category.
