listen h.ear and feel the price is alrite. but given the choice i will choose top up for 1r.

momentum big is good. not sure about the small

Try before buy 

There are still many good portable headphones in this price range

my personal experience, MDR-1A deliver well balanced music quality. punchy bass, clear treble

alternative, if your budget can set slightly higher, can consider MDR-1ABT. now selling price RM1099 

MDR-1ABT is hi-res bluetooth headphone. this is ideal for those who prefer listen hi-res music with wireless headphone 
if other brand i can't commend, but if price range around RM900, MDR-1A is very good headphone. i'm listen music with 1A, too 

Highly controversial.
As far as I know, for such short distances the physics and maths says it doesn't matter even if you use a super conductor. It does change, but you wouldn't be able to hear them anyway because the changes are in the hundred thousand Hertz range.

I have noticed a change from changing to a shorter cable (1.2m vs 2.0m), but since I don't have an original to compare it with, and I have had only a short time with it after spending over a year away from it, I'm not properly equipped to say definitely that it does change the sound. Besides, I have modded the drivers before changing the cables (Grado SR60i, easy to open up). The main reason I changed it was so that it could be more practical, and the stock ones have crumpled sleeves so they don't look good.

Some more intricately weaved cables with different metal conductors (silver cladded copper for example) can have different capacitance and inductance which acts like contours and filters to the headphone drivers, which would change the sound. But, the cost of an audiophile grade capacitor and inductor with comparable values do cost much less than an over-engineered headphone cable, and can easily be integrated. No one does that though.

What matters is the connector quality. A robust jack with a proper strain relief helps with reliability and longevity.

Audio Technica M50X

Beyerdynamics Custom One Pro Plus (RM690 @ Jaben, can confirm with them)

If no one has tried new sony MDR-100AAP h.ear on series they should go try it

What's the non-promotional price?
I was going to get the Audio Technica MSR7, but the price went up to beyond my budget.
