I do not live in India at the moment. Therefore demo options are available in the part of Europe I live now. Also, last year I took my AK70 dap with my Beoplay H6 headphones to listen to other DAPs and headphones at the Munich hi end show. I bought the AQ nightowl, because primarly it was the most comfortable closed back headphone to my headshape which sounded well detailed, fast enough and wide for a closed back . At home , I had hd 650 and 600 and 702 of which I retained the 702, because it was totally opppsite to the AQ's sound. Funny thing is I bought HD 650 3 times, 2 times used and one time new in last 4 years when I missed them. I never bought the same headphone multiple times other than this.Do you blind buy these based on reviews ?
Even though I recommend 6xx, what u expect of a headphone also has to be considered when buying it.
