I anyone interested, you can ask the engineer who made this themselves over here at HF.

Mine has arrived today with a resounding msg from the home minister , "You bought another headphone!"

Anyway the hype (both pros & cons) about these babies were true. Let's start with the bad,
1) non-friendly cable which I easily accustomed after a whole
2) fit

All what has been great about MH1cs already been told and they are true. This by far the best sounding sub RM 300 you can get on the market right now. Bass really goes deep but without the boomyness of bass signature. It's like FX101 bass with the sub bass tightened really tight. Good extension on the highs without becoming fatiguing. Just barely enough for my treble fix.Warmish mids.

If you read the reviews, there were few 2-3 non-recommendation as they sounded crap & to me it was. It was muddy and lack of detail, like Beats but without the the extensions at both ends.

Turns out, from my amatuerish hypothesis, the reason is MH1 has a focused narrow beam of soundwave. With this laser like beam, a wrong insertion would ends up the soundwave bouncing around the walls in the ear canal thus the sounds bleeds to the eardrum. This caused the horrible signature that most of the complaints about.

Fitting is the key as wrong insertion could provide a significant difference in sound quality. I speculate that when people said MH1Cs started to shine after burn in was due infact to the ears adapted to fit the IEM better.

With a proper insertion or rather for me a semi insertion, the wave was able to be focused straight to the ear drum which upon impact, be prepare for an audio nirvana any sub RM 300 headphone could provide.

I found for me to get that soundwave pointed straight to the ear drums is by wearing them somewhere between earbuds and IEM. Not too shallow & not too deep. Even though it is shallower than normal IEM, the isolation is better and the rubbery texture did hold well to prevent MH1C from falling. The stock tips given gave a good isolation, better than comply tips.

TL;DR IEM as hyped. Even for RM 250, it is definitely worth it but at current sub price of USD 30, it is a steal!

Wonder why MH1C is sooquiet around here?
