More notes and thoughts on the NX7. For the price, the hype was worth it, regardless of the opinions of the naysayers who don't hear the sound the way I do or others did. Still respect your opinion, guys and gals!
The bass EQ's like a beast! The dual CNT drivers, well balanced if a tad behind the mids and highs, when EQ'd or boosted behind either a DAP or DAC, can come in very powerfully and deep. It can dig and provide some thumping sub bass. Punch and power if you want it. I put it on bass boost through my Fiio Mont Blanc and I got the thump! So you bass heads who want world class clarity and timbre as well as BOOM BOOM can call on these with confidence.
I agree with
@peter123 as far as the not so 3D sound, but I don't think that was the directive of the tuners. Some earphones that are 3D don't sound that great because it makes for artificial imaging. (my KZ, T2pro, and to some extent my TFZ's can provide some exaggerated 3D imaging). The soundstage is also average, but I wouldn't call it narrow, just not expansive. Not like the stage of those Senn's or JVC. That's WIDE. These are more in line with the Crescents or my Sony's.
Clarity and details retrieval are their strong suit. These things pull details that are incredibly minute. They are the deepest diggers of any earphone in my collection. Easy. More so than even the IE800 or the FW01. From quiet guitars in the background to whispers into the mic to a keyboard or flute buried in the mix, the NX7 will make them audible to your ears. Even old ass ears like mine.
The highs? They don't bother me at all, but then again, this will be the main contention for anyone who doesn't like their sound.
Still, for the price, and for critical listening with great EQ flexibility, they are very hard to beat, unless you want to spend a lot more money. It's up to you.
