I seriously think that it makes no sense that you justify your objectifications of subjective tastes by saying that you are a newbie and you must be forgiven.
Just stop being a newbie
Be more specific when you compare headphones. Try to divide the "more or less objective" (detail, soundstage, presence, cleanness, clarity, transparency, frequency range and response) from the totally subjective (amount of bass, mids, highs, so called colour/signature).
By saying that the M2 is "better" than the mdr1rbtmk2, you do not let people understand "in what" and/or "why".
And it can be a never ending interchange of posts between those who say "no, I think A is better" and "no, I think B is better".
Solution? DESCRIBE the sound signature, rate the sound quality (= the sum of all above mentioned "objective" qualities).
Sound quality = good, bad, decent
Detail (quality) = more, less, good, ok, decent, mediocre, excellent
signature = warm, v shape, bassy
bass (quantity) = boosted, neutral, I would like some more, I felt it as too much
sound: there is NO such a thing like "sound". Headphones do NOT "sound" good or worse. They have a good or less good sound QUALITY (all the amove mentiones "objective" qualities together) and have a specific sound signature.
As you say "first of all I am a newbie" each of two posts you write, I though it was time to put an end to this newbie thing.
EDIT: I thought you want to put an end to it.
But yes, I also want.
