BUILD:   It's solid, can likely withstand abuse, but it doesn't look high end or refined, imo it looks a bit cheap. The jutting out screen is set on a plastic bed, the screen covering feels like plastic not glass, but can't find info on it. The aluminium case feels very sturdy and looks very good, if only the whole dap followed suit, the jutting out back cover is thinner aluminium and doesn't feel as nice or solid as the main body and looks out of place.   USABILITY:   I'm not a fan of the side buttons, they are thin and harder to press than...

I'm listening to the N6 with Ultrasone IQ Pro.   On to the sound, it does sound very good, very effortless, airy, balanced, honestly nothing is lacking from a technical standpoint, many daps I'e heard I could come up with several faults with easily, but N6 really has less faults than the majority of dap I've heard, in fact the N6 only has one fault in it's sound imo, which is quite an achievement.   How N6 compares to other dap's in a nutshell:   DX90 (fw2.3) has a bit more heft to the sound than N6 (fw3) which has a lighter touch but details...

I will mainly be comparing to A65.   Build of these is excellent, but not quite as nice as A65 due to the half plastic housing. It is of very high quality though, it shouldn't affect durability.   The bass hits way harder than A65, but is also faster compared to the slower thicker bass of the A65, It's a tie for me, I like some aspects of both bass performances, my ideal bass would be right in the middle of both styles. The mids on A73 are clearer and better separated than A65, but also thinner, male vocals sound better on A65 while female vocals...

Just a short review, as there is really not a lot to say, which is a good thing, nothing to complain about with these.   Build is excellent, they feel supremely solid, I mean even 1k+ iems don't feel this solid. The cable looks and feels great, is tangle resistant, and feels very robust, gives the impression that it won't crap out at the strain reliefs. The jacks, divider and iem housing are all made of what feels like steel (I don't know what material it actually is) but it certainly feels more solid than some other iems that use aluminium, maybe...

I have a lot of closed headphones. These are as good as any other closed headphone at this price, in fact, I prefer these to the DT770, K550, UE6000.   The DJ1 Pro have a bigger and airier sound stage of the four headphones.  Treble is refined and detailed but doesn't pierce like 770 and 550, while UE6000 treble is lifeless. Mids are recessed on all four headphones, but not too much, the DJ1 Pro still has the most fleshed out mids of the four. Bass is in line with treble, only slight V shape, DJ1 Pro bass hits the hardest and deepest of the...
