Ok serious question, How similar is the sound signature of the M300 to the Isine 10 & 20 with the stock cable. I have fallen in love with the Isine 10 using my HTC 10 and Elemental Watson. If the M300 are anything similar I will pull the trigger!!! I neeed to knowww now, and I wasn't a big fan of the cipher cable. Tried it with my friend IPh8, it sounded good but not as good when hooked up to a good desktop amp, treble sounded a tad sibalint.
