I have to agree with otto and loomis B9s on these. The N3 is not ready for prime time. My read pretty much highlights the same flaws. The highs on these are a complete fail. They would have been so much better off not using the piezoelectric driver for treble on these. Believe it or not this Fr is very similar to the Fiio FH5. But a much lesser experience. Will post my review of them soon as well.

So I am starting to understand the OEM that produces these iems for NiceHCK a bit more. It seems they sit around in their weekly meeting and do a round robin of great driver ideas for earphones to bring something new at a cheap price. Design them. Tune them once and slaps a name on them and send them out the door. Regardless of sound.

In any case. I feel bad for Jim as he is probably thinking we all are gonna love these. Oh well it is what it is. Onward and upward.

It appears that different people use different frequency ranges for bass, midrange, and treble. This is ok as they are not unambiguously defined. For some, treble starts at 1.2 kHz, for others at 4 kHz. While I intuitively side with the 1.2 kHz fraction, I have always used the 4 kHz and indicate this via a link in each of my reviews.

Any recommendations sub $100 ( value for money )

BQEYZ KB-100 - hard to beat for a near neutral with great build quality at $50.

In having more than one Piezo in the review queue at the moment. I am noticing a couple things hold true on all of them.

1.) They are more power hungry than the specs would suggest. All show low impedance and high sensitivity specs, and yet still consume at least 25% more power to really open up than others with the same ratings.
2.) Without that additional power, coherency suffers to some degree on all of them and worse on some than others. The **** likes the Opus#1s on high gain while the N3 really prefers it paired to the xCan to really do its best work, (Which is still nothing special as others have already noted).

any issues with iPhones?

any issues with iPhones?

Can't say that I have tried it yet. I will this weekend as part of my review process but I'd guess the iPhone is going to be slightly under-powered for them.
