Thank you so much everyone and apologies for the late reply. I had a demo of these and I must say, they sound very good. However, cutting out the drone of the engines would be an order too tall for them. I was recommended and have been doing some reading on the Shure SE535. Too bad I can't demo them here. Weighing these days whether to take the US$500 plunge or not.
Once again, thank you very much and my compliments on running this place which is a treasure trove of knowledge for newbies like I.
