Hi, I'm thinking of getting a noise isolating earphones. Looking for one with really good sound insulation. The main reason is to double up as earplugs block out the ambiance noise of my office (I have very noisy colleagues and wearing industrial earplugs will look silly). Of course music comes second, but its not really so much priority. Looking at more commercially available brands like Philips or Sony. Please share if you've ever used an earphone with really good passive noise reduction. Thanks

Thanks. a budget of about RM200 will do just fine!
