Thankfully, there are no restrictions as to who may or may not review an item. The more regulated a setting, the less of a hobby it is.
In any case, who determines the parameters?
Do the regulations (if there were any put in place) favour those who determine the parameters?
Who defines when someone is competent to review an item?
What is a review?
Who determines what is the definitive categorisation of a particular tier, in what is, in essence, a subjective issue, namely, how we individually perceive sound?
By stating our views and impressions, on these threads, however brief, are we
ALL not "
REVIEWERS"?
I had the impression that was the entire point of hobbies, and we congregate here on Head-fi to share our views with like minded people in an interest, we share, in this instance, earphones or audio in general.
There is always the risk that such regulation of a
HOBBY slams the door firmly shut on, a young person, or someone with a novel approach to how we percieve sound and here
I applaud you @AmericanSpirit, for your novel approach to categorisation!
Just my thoughts!
