Design & features
The build of the pair of earphones themselves are decent. They’re made out of very lightweight aluminium all around. They’re not made out of typical cheap plastic.
The eartips themselves are made out of silicon as usual, and having the usual S/M/L size is very usual. Then there’s a rather slim flat cable, which is quite typical in today’s standards of earphones.
The other additional feature that it has is the in-line microphone and button. However, what’s special about the Cooler Master MasterPulse Earphones is the colour-coded left and right channels on the earbuds themselves.
You can also determine which side is the left or right channel by determining where the in-line controls are. Usually these controls will be on the right channel, but Cooler Master did the opposite and put it on the left channel inside – the one with the blue earcup. There’s no right or wrong side to put the audio controls at – just a matter of personal preference.
Speaking of the in-line controls, Cooler Master mentioned on their website that the in-line button can be used to control music. I’d like to point out that your result may vary. There isn’t a clear standard on how Android smartphones handle in-line button inputs, and most of them are controlled via an app anyway.
Personally, I use Spotify – which works for 2/3 of the functions, and Poweramp which worked flawlessly after some app tweaks. Again, it’s software-dependent – so don’t get mad fi it doesn’t work for you.
