is NC really important or critical to you? cause for NC there is nothing below 200, they are for premium pricing material

i think.. i think.. near thousand ba~

I think with NC you won't get a very effective voice reduction in the first place. A very good passive noise reduction would do fine. But still at RM200, I can think of only IEMs that can provide a lot of noise reduction. But I have limited experience with headphones, and the only one I'm using is an open-back headphone. That provides like......absolutely no isolation whatsoever.    The best ones (IEM) I've used needs at least the minimum volume of music to completely eliminate out side noise. The only noise would be from the music.
