Here is some info on the MX2, see the mini review of 6 portable cans in my signature below.
Anyone want to buy a mint pair of MX2s?
Pretty solid review. I agree, they are missing the extra clarity and detail of much more expensive cans, but there are much worse out there for $100 and under.
With all the discussion of modding these CT-H02s, I'm surprised no one mentioned this:
The rear caps are easy to remove by prying them off, exposing the back of the driver and the wires. So you want to be careful not to disturb these. But try listening to them with the end cap off. This turns them into semi-open cans, and the presentation changes accordingly, a bit more spacious. Without any appreciable decrease in bass. I prefer this presentation, but obviously don't want the "guts" to stay exposed to damage this way.
Turns out you can get the benefit by only snapping 2 of the 3 tabs of the rear caps back into place. This creates a small gap between the cap and ear housing which is enough to create the extra spaciousness I prefer. And it's reversable - just snap the third tab into place to get the stock configuration back.
These are now $18.62 (black) and $16.23 (white)!
Amazing headphones for the price. Simply lift the response around 4 kHz and hear the near-reference sound. I use the following EQ setting:
Center Frequency: 3,800 Hz
Gain: 5.0 dB
Center Frequency: 8,500 Hz
Gain: -2.0 dB
