After having a long time with the N3 I finally have the time to write a short review based on my experiences.
Build quality is quite good imo. So first onto the stock cable of the N3. The 90 degree jack has a good and sturdy strain relief and the jack feels extremely solid. However there isn't any strain reliefs on the y-split so rough users might want to take care of it more. Mic is very responsive with clicks. No delays or lag and the microphone itself is clear when talking through it to other people on the phone. My 1 gripe about the stock cable is that is has a bit of memory in it so it when first taken out of the packaging, for a few weeks the cable keeps returning to its circular shape coiling around my pocket. But after a few weeks of using and "pulling" it becomes much more straightened and tangles much lesser now.
To me, the N3 are slightly V-shaped and dark sounding in overall balance of the sound frequency reproduction.
This humongous bass is very very very controlled and yet at the same time punchy with a little more than average sub bass for its "fun" signature while still maintaining good control.
As a V-shaped signature, yes the mids are a little recessed especially in male vocals while female vocals apparently have a slight peak in the upper mids which makes them sing with a little more energy than male vocals. Male vocals sound slightly mellow due to the big bass while female vocals sound lively and engaging. Having read some reviews written here, I do agree that the mids are its weakest point among the 3 main frequencies but I want to comment and say that I think that IMHO this is as good mids can get when put together in a strong and bassy signature. i truly believe that anymore bass boost or boost in the vocals will make it sound grainy, too peaky or too muddy.
Now moving on to the treble. I really love the treble on the N3. In fact it was this treble that led me to buy the N3s'. Most treble I hear tend to either sound coloured( dynamic driver treble) or sound peaky and piercing or just too insignificant especially in bassy signatures. However this treble is very airy, crispy, very very dry and yet non fatiguing. It is slightly rolled off. Also the treble is extremely NOT COLOURED. Its as if cymbal hits really sound like cymbal hits and not sound like "recorded cymbal hits". It's very natural and soothing to the ears.

Now I after saying all this good points about each component of the frequency, I would like to point out the negatives now. Especially in terms of its overall sound. Since it is a V-shaped signature it should be lively and engaging right? Nope. To me the N3 are a V-shaped BUT YET boring signature. I know it sounds weird when I say this as most people tend to put V-shaped and "fun" together but this isn't the case for me. There were times I wanted the bass to hit just a little harder and times where I wanted the vocals to shine just slightly more.(In fact this earphones have made me fall asleep the most on my commutes among all my other earphones) But they failed to do so due to their SMOOTH signature. I always tell my friends I will take any smooth sounding earphones over peaky/too fun earphones. However this time I'm gonna have to take my words back. The N3 really are too smooth for my liking but then again, it boils down to preference of sound signature. So overall do I recommend this earphones? I would say a maybe due to its HIGH PRICE. In terms of its sonic ability, I really think there is no other earphone that could beat the N3 in its price. But however I feel it is too costly for the N3s', especially when there many $200+ range earphones that could be on par/fall short to the N3, making them not worth the extra $100 to put in into the N3. However if you can get a cheaper price than its retail price like I did.... Just go for it
Edit: I forgot to talk about sound stage and imaging so I shall write a small paragraph for it.
Soundstage is relatively spacious in width but small in height with a fair amount of depth. Soundstage is above average at best that feels like a studio sized room. It also does not have the immersive feeling that JVC FX woody series have.
Imaging is extremely good especially since the BA treble driver is differentiated from the bass driver. Instrument separation is excellent and pin pointing guitars drums and vocals is easy.
