Interesting idea, I have sent the info to a good friend, who likes music, not just pop music, he has not made the purchase yet. I am thinking on offering them to my daughter, Christmas is coming, who also likes music and like listening on headphones.
My concern is: can someone who is not critical about what he or she listen with, really appreciate what those bring to the party? Or does it takes years of trying to understand what is not right, is it the gear or is it the recording, to really appreciate what the Zero is revealing.
If one as not struggled to get where he is on his quest to great music, can the clarity and frequency balance be appreciated? I fear, many will be disappointed when the casual listener does not get how special those are.
If one ask for a recommendation, then it is a different story and I would gladly point that person to the Zero as the IEM to purchase.
