+1 on the comparison. N5005, 846s , and UMPRO50 are all in the same ballpark.
Ok, so I have had my 846's for little over a week now. Still in the honeymoon period of course but happy to provide a little comparison to the N5005's which I had for over 18months. My listening preferences are varied. Worth noting I enjoy a slightly bass bias setup.
I also have a desktop setup which consists of Denon D7200 and the ever popular 58x. Both are connected to my PC via usb and custom XLR balanced cables, using the Fostex HPA4BL. I probably use the 58x more, as they are just so easy to use. However, when in the mood, nothing puts a smile on my face as good as the D7200 does.
Anyhow, back to the IEMs. 99% time I pair my IEMs to my smartphone when on the go, in the car, or in bed. Currently I have the Samsung Note 10 plus using the FIIO BTR3 (soon to be upgraded to BTR5 when my pre-order is fulfilled). I don't use these IEMs for the gym or running. Whilst I am sure you can, I prefer to use a cheap bluetooth set that i can throw around/ get wet and not worry about.
Packaging/ presentation:
At face value, the N5005 present a more premium/ luxury appearance by quite a distance. Both seem well built. Whilst the N5005 do give off a more luxury vibe, imo, it should not influence buying decision when comparing the two.
Cables:
The bundled cables with the N5005 look and feel better quality. I actually enjoyed having the in line remote/ mic from the N5005 as I used this plenty of times for work conference calls. The 846 cable doesn't look as premium and is definitely more stiff meaning not as comfortable, either. That said, sound quality wise, I can't make out any difference. I will probably look into a custom cable in the near future but i'm not in an immediate hurry.
Comfort:
Both are reasonably small IEM's and are equally very comfortable. I was able to achieve a secure fit with both and can listen for hours. No discernible difference. I would consider my ear size average.
Sound:
Both sound excellent and are an absolute pleasure in their own right. But they are different.
The N5005's appear more reference to my ear. Bass is detailed and can be powerful, but a secure seal is absolutely crucial. Playing around with the filters does make a difference but they are (rightly so i guess) very subtle. I settled on the bass filter after a month or so just using the default reference. The signature note of N5005's is the clarity and bright highs but this is never fatiguing or too much - just took a little time getting used to. The 846 does everything very well for my tastes, just with more bass. Maybe at the cost of clarity if you were to make a direct comparison? I'm not sure, and, if so, it is not something I feel I am missing.
In hindsight, I should have bought the 846's first time round given my listening preferences but alas i went for the newer shinier model not having the opportunity to test the two first hand. That said, if I was to never to listen to the 846 and keep the N5005 I would have remained happy. Just a shame I had an issue with the earbud failing on me twice (as I have mentioned in earlier posts).
Thanks.
