More seriously, Campfire is kind the brand right now, and with a lot of fans comes a lot of people who are gonna share their less-than-keen views on the product. Singaporeans have a much higher degree of access to products that us Americans for the most part have zero means to try, so they're just going to be pickier with what they like vs. what they don't like, or just have more experience in general. No brand is going to receive 100% praise across the board, so please learn to take criticism.
This, doesn't make a whole lot of sense. What does being from Singapore have to do with access or having "better ears?" Is the inverse not true for the boutique brands we have here in the States that don't get the same exposure overseas? Some of us have had the IO for over a week now and I can say my impressions today are quite different than day one. Same with the difference of listening through my phone compared to my amp/DAC, or listening to MQA via Tidal and just streaming through Google Play Music. And we still haven't talked about choice of genres, tips used, etc.
If you're going to be skeptical, it should be across the board and equal and you not just picking one or the other. Or, you could try the IO yourself and share your impressions like the rest of us have been doing as well. I'm not even saying this individual is wrong, but it does sound odd considering my listening experience and that of others.
Personally, I enjoy the IO for what it is and the price bracket they fit in. I enjoy them more than my MD+ and ER4, EDC3, etc. That are aiming for a similar FR. They have faults but I really have to nitpick and do a lot of comparisons. And it arguably comes down to the genres of music I'm listening to and my mood that day.
But, like an above poster said, listen to what you like and trust your ears. If I listened to all the nonsense on the internet, I would have never ended up with my Shure 846s that are still one of my fave all BA IEMs to this day. They are still arguably the only all BA IEM that gets the lows right with speed and texture, especially with the black filters. Of course, this trick is due to their well engineered low pass system, but I'll be damned if it isn't a VERY good trick that no one else has been able to replicate (amongst their build, accessories, being sweat proof, filters, etc).
Just my .02 cents on the matter, either way.
