JVC HA-SZ2000/1000 Impressions Thread - Page 31

post #451 of 1300

Finally with my Home setup.

A bit more power definitely helps these cans... but still the lack of 'clarity' is not making me enjoy them as much for now.

Listening to Kaskade - Room for Happyness and directly comparing:

 

(maybe not a fair comparison... NONSENSE, all compares are fair! :p)

 

JVC definitely has the BIGGER more rounded Bass, definitely a few more dBs in the bass section (sub/mid-bass), also everything is more "in your face" on the JVCs (probably due to lower impedance and me trying to match them volumes lol), yes, even the mids... BUT the lack of clarity borders on "budget/mid-fi" to me (i.e. mids less clear than AT M50s, Shure 840s, etc. ... only on head-fi those two are "budget" cans LOL). It's very apparent on tracks such as:

 

 

DMB --> http://youtu.be/MNgJBIx-hK8

 

Orquesta Macabeo --> http://www.youtube.com/watch?v=6-VM3il1VgA

 

 

Now, lemme tell you, these guys like equalization though... a couple of modifications and I found them a bit better BUT I DON'T use eq usually. In fact, I prefer to get rid of headphones and just buy another one that doesn't need eq'ing ;) Oh... and that Bass... MONSTROUS when eq'ed!! Holy shhh...

 

Anyway, still way early to tell.

I usually use new headphones a couple of weeks at work where I spend most of my time. 

Will definitely take these tomorrow and the rest of the week to keep on testing.

As of now they don't blow me away, but they are not bad.

I'm a firm believer in "brain burn-in" so, we'll see if my ears/brain get used to their sound and what they have to offer. ;)

 

 

Check.

Told you about DAT Bass!

I really think you need to bash their diaphragms with serious burn in. If you take a look at the early impressions of the HA-s400's/500's many people have issues with clarity, but after a few 100 hours they start opening up and the mids get smoothed out. I don't see how this 30mm CNT driver would be any different. I did not personally believe in bur in until I bought the s500's, burnd them in aggressively for 200 h and compared to a basically unused pair that my friend had, BIG difference!

^ What BOS said!!! beerchug.gif At least a week or 2 to get those stiff CNT drivers nice and loose.

That's how i swing. wink_face.gif

 

My FXZ200s didn't start to sound great until like 1000hrs of burn-in with bass heavy EDM music, so who know how long it takes to break these massive SZs. triportsad.gif

Carbon nanotube thin films produce sound by a thermoacoustic effect.  Compared to a traditional magnetic speakers, there's almost no movement of any components: 

Quote:

The temperature oscillation of the thin film excites the pressure oscillation in the surrounding air, resulting in the sound generation. In this process, it is the thermal expansion and contraction of the air in the vicinity of the thin film that produces sound, not the mechanical movement of the thin film itself.

 

Here's the published paper and the subsequent patent from the group that first worked with carbon nanotube acoustics.

Oh no don't try and provide objective data and scientific information!

Actually, I removed what I said about placebo to avoid burn-in discussion.

Regarding burn in... yeah, I will not go there...

 

Got my Monster NCredible NPulse headphones today...

I don't know why but I have a feeling that I'll probably be liking those more... eek.gif

So THIS is how they're making all that crazy bass: nl-2008-02750z_m001.gif
