Official JVC HA-RX700 Owner's/Appreciation Thread-Only Unmodded Observations, Please!!! - Page 3

post #31 of 93
I'd say the RX700 is easily surpassed by the DX3, yet I sometimes prefer the RX700, (or RX900 or D1001) as the DX3 can be too detailed and fatigueing for some kinds of metal.
I won a DX1 on ebay earlier today. Not that I need another set of phones, but $30 is a steal. My sources are a Pioneer surround reciever with a Denon CDP, and my iPod connects to a Kenwood amp with a realistic EQ.

I just ordered the RX700 headphones and wanted to know the best way to burn them: should my playlist consist of just 1 song or different songs? different kinds of music (classic, pop, punk, metal, rap...) or just the one i mostly listen to? do i need to let them "rest" once in a while (if so, what the recommended frequency? 1 hour every 10 hour?..)?
Just so you know, I listen to:
- punk (punk, punk rock, Irish punk, hardcore, ...) => 70%
- other rock music genres (metal, acoustic rock, pop...) => 20%
- classical/OST => 9,5%
- dance/techno => 0,49%
- rap, hip/hop => 0,01%

Thanks in advance for helping me out...

I would put the music on shuffle and add absolutely your whole entire music collection. The RX700 and RX900 need to take a beating before they sound right. Mods help too but this thread is for unmodded so I'll not go into that.

Alright... I'll just do that. Thanks!
I really can't wait to get them and put these babies on my head

I have about 10 hours on my pair and wanted to give some impressions....

Out of all of the cans listed in my sig, these are quickly becoming my favorite, and they're not even close to being burned in. They have better mids and highs than my open Philips SHP895 (which are my current favorite cans, with some added bass boost), but the bass is a tad more loose. They sound great with everything from Metal and Rock to techno, and rap. I haven't found a song that they sound bad on, unless it's in the source material. These even pick up pops and crackles in the recording that other phones miss or are less pronounced. Playing Finger Eleven, Drag you down, for example, there are slight crackles in this recording that I never noticed before (overprocessed). The mids are very nice and rich. The treble is slightly rolled off, but not congested. That's a good thing IMO as I am very sensitive to sibilance, harshness, etc... They are truly a jack of all trades. Mildly analytical, and powerful and fun at the same time. And I almost forgot about the bass. It's not overpowering, but if you want these things to rattle your brain, they will do it, with room to spare. I normally use a little bass boost, and these just come alive with it enabled. I feel like I ripped someone off, considering these are 35 bucks. The bang-for-the-buck factor is crazy. The only interesting thing to note is that I can feel the housings vibrate (by touching the outer earcup) quite a bit when playing anything with a fair amount of bass. My SHP895's don't do this, even with a similar amount of bass. Makes me wonder if this could color the sound somewhat.

Anyway, I hope my impressions were helpful.

Sorry to post twice in a row, but if burn-in is real it's a very weird thing. When I first got these, there was no sibilance at all. In fact, the treble was somewhat rolled off (which I prefer). I listened to them for about 3 hours, then let them burn-in at a moderate volume clamped to a stack of xbox360 games to maintain a seal. Today I pick them up and they're horribly sibilant. Sibilant even on tracks I haven't known to be very sibilant. Anything from Burn Season or Chevelle, for example. I was loving them when I got them, but now, they're suddenly fatiguing. The rest of their sound signature hasn't changed much, though.

To anyone who has checked during the progress of their burn-in, do these go through a sibilant phase? Hopefully if I continue burning them in tonight, they won't sound worse tomorrow.

My K81DJ's /w inserts removed have always been a little sibilant, and the JVC's are now worse!

I have a heavily modified version of RX700 (lots of dynamat, foam, felt with circle holes clipped off, and thinking of getting a recable because the connector thing is somewhat broken.) but yeah, I also noticed I have the weird sibilance problem with the cans. With a bit of EQ however, its good as solved.

Read this, and download SineGen and one of the EQ things provided at the bottom of the post. I personally use Foobar with the VST wrapper and the freeware EQ version.

Your and my ears are different (maybe significantly) but try checking around the higher frequency. I got a uber spike somewhere around 5800-6000Hz. You might also find that the cans begins to get really rolled off soon as 7KHz hits.

cam94z28: I actually found the RX700 to not have enough treble so I don't own it any more. You'll definitely hate the HA-DX3 then.
post #39 of 93
I love my RX700s. I always find myself listening to them for way too long. I also found a way to fix the rolled off bass response since I do like some nice round bass. I don't own an actual headphone amp, so I just use my 70s vintage Marantz 4415 receiver. With the loudness function on, they sound fantastic (to me).

Burn in also really opened them up. I didn't get any real bass until I plugged them into my stereo with some serious EQ which beat on the drivers for a few minutes. After that they sounded much fuller.
post #40 of 93
does burn in help the midrange significantly? Because I found the midrange was far from my liking with the brand new ones my friend got. Sounded like plastic, and thin. There also was this disconnect between treble and vocals, this weird gap in frequency response. I didn't test this, but I feel like if you ran a test tone up the spectrum, it would just drop off at one point just above the mids, before picking back up again.

Gonna have to buy my friend's off her cause I promised her she'd like them!

Interesting how people hear these so many different ways. To me they are still fairly sibilant, but it's weird how it comes on. For about the first 30-45 mins the treble will be tolerable, but suddenly it'll come off as harsh. None of my other cans do that. The mids can also be slightly honky when listening at higher volumes. Maybe I should try one of the mods out there for these.

Even with the above, techno/trance like Armin Van Buuren sounds really good

I just couldn't pass up such a great deal on Amazon, so I got some. arrived today and have been burning in overnight. First impressions are guite favorable. As you can see from my Sig, I've auditioned many top contenders and I stayed away from JVC's because all the other major brands dissappointed. I think I'll take a look at some JVC models for a while. I would put them on par with a pair of unmodded Denon AHD2Ks and at the price of the Denons, I could have 6 pairs of theses from Amazon.

That is exactly what I said; bought these a while back for some cheap knock-about cans and ended up selling my D2000s. To improve the 700s do the foam ear pad mod, completely reversible but makes a huge difference to the soundstage which is already quite good stock.

Edit: Just noticed you have the Milian Acoustic SVT's... I was thinking about buying just the headphone cable and recabeling the RX700s with it, I presume you like the SVT's for there price also?
post #44 of 93
My reason for buying the SVT's was for isolation. (Like being in a sound booth). The drivers are only KSC75's (Yes I checked). I still have them but never listen. You can email Maxwell at Milian Acoustics and he will sell you the SPOFC cable seperately. ( made several IC's with one I bought). The cable is pretty big and stiff. Not worth the hassle over Mogami or Canare Star Quad. eBay seller "navships" sells a nice SPOFC cable to DIY. I have it on my modded Denons and it adds a good deal of clarity to them over the stock Denon cable.

Unless you go realy high end, I think the stock OFC cable on the 700's is pretty nice. although I balance cable all of my cans with 4 pin Mini XLR connectors with multiple adapters for any amp.

Does anyone have a frequency response graph for the Harx700? Or can anyone tell if these headphones are more or less neutral / emphasized bass etc.? Because I like what I head, but I still want to know what excactly I am listening to
