It is easy to pay top bucks to get great performing earphones.
but getting a low budget earphones that can perform greatly is more thrilling.
and the portable market recently is getting more and more insane with their pricing.
who knows one day we might hit a jackpot with low budget earphone that can perform closely to the top bucks one.
I do agree with both schools of thought. It is rather similar to watch collecting; where for me as a budding collector, will find some good and cheap pieces e.g. Seiko, Timex, and slowly move up the ranks (and usually correspondingly, price). Once you amass a growing collection, some people will keep their collection and have it grow even more, and some may trim their collection to a few key watches, to differing extents.
In my own earphone journey, I am also reaching a point that I have quite a diverse collection (not to the point of TOTL, in the high $XXX and to $XXXX range), and I feel my A4s, with a couple more earphones, are hitting the sweet spot. I would admit not listening much to my KZ IEMs as much as before, despite them being really good bang for the buck earphones. Whether I will start to trim my collection to a select few IEMs, is still an unknown though!
