  I wish they had a cure for Tinnitus. I wish I could "hear" silence. Quality and balance I'd say are the parameters. Thanks for the info. I will never buy a custom IEM though. That's quite great then.

We have multiple experimental drugs that are not out of the testing phase, but even so, none that I see are real long-term solutions. Many seem to be promising for sub-acute relief of threshold shifts, but real, permanent reversal of neural damage seems pretty bleak at the moment. Psychoacoustic treatments are what most hearing aid companies propose as relief for tinnitus, but it's been known that these treatments require constant re-conditioning (read: training) or else the tinnitus will come back.

Interesting. Neural? I thought it was just hairs in the ear that fell out.

I'm not sure if you're making a joke or not, but I'll answer seriously anyway.
 
"Hair cells" of the ears are not hairs. They're polarized cells that contain stereocilia which help convert mechanical energy of the fluid in the inner ear (the energy comes from the conversion of sound waves) into a directed flow of potassium ions across the hair cell. The flow of ions is what ends up becoming the neural signal your brain will process as sound. Constant stimulation of these hair cells (too much ionic flow) will cause them to "tire out" (ionic imbalance), and may cause them to die. These hair cells are grouped by frequency, and if there is a loss of a significant amount of them, the neural ganglia upstream of your auditory nerve will have problems summing the complex signal that is your hearing, and your brain will attempt to "fill in" the partial signal with the sound you hear as tinnitus. That's usually how long-term tinnitus happens, or at least as simple an explanation as I can try to make it at this point.

No joke. I've been school. Thank you.

It has been asked before, but that's okay --- I've not done a direct comparison between the DN-1000 and 2000J, so I can't say for sure, but from all my auditions of the DN-1000 (don't own it), I found it to be sibilant, sometimes to the point of irritating. I don't get the same feeling with the DN-2000J, even though it seems to be brighter overall.
 
 

Thanks for the reply. I didn't find the DN-1000 to be overly sibilant for my tastes. I look forward to what the DN-2000J's have to offer. 

 

[tomscy2000]

Tried some wide-bore biflange tips on the DN-2000J that had originally come with the RE-262; they seem to do the best job of smoothing out resonant peaks out of all the silicone (non-foam) options that I've tried, including Aurisonics SureSeal tips.
 

 

[Raketen]

Hmm... I didn't have much luck w/ similar biflanges- are you using any spacers? Had trouble getting the sureseals to actually stay on the thing.

The SureSeal tips managed to stay on, but I didn't like the way they sat flimsily on the stem.
 
No spacers with any tips; I don't like to bother with them. To get a good fit and seal, I have to use an over-ear wear style with these biflange tips. It allows me to get a deeper insertion.
 
Wondering what you're coming from in terms of experience with IEMs... EX1000, FXT90, what else? It seems like what's going on is that when the midrange is warmer (either with boosted lower midrange or dropped upper midrange) with respect to treble, you systematically hear less sibilance. That's nothing abnormal, but a typical psychoacoustic effect.

Can more of you guys use the bass enhancing accessory and report back the results? Thanks.

 

[Brooko]

I think you got my comments from the review right?  Increase in sub-bass, and lower mid-bass (personally I don't think they need it).  Introduced driver flex.  I had issues with vacuum (when vent was blocked) - swallowing, or any pressure adjusting.

 

[Raketen]

Only used it briefly-without, missing the physicality of the lows & subs a bit, with I can feel some pleasant rumbling sensations, overall sig seems unaffected if a touch muffled in the treble/details compared to w/o. I like it with the bass ring but with the aforementioned side effects I'm inclined to leave it off.

<p>aurisonics ...get the as1plus I think the customs are called </p>
</div>

<p>&nbsp;</p>

<p>So Aurisonics would be the fastest? Like how long? do you know? thx again Moochill</p>
</div></div><p>&nbsp;</p>

At the most a month , but you can ask them

How's the treble compared to Titan? Titan's are on the verge of sibilance for me. Thanks.

 

[RedTwilight]

  People who are sensitive to sibilance should be using the Comply foams with the DN-2000J. The peaks sound a lot smoother, even without the "x" series wax guard. They should also wear the DN-2000J as deeply as reasonably possible --- a deeper fit will always push quarter wave resonances in the treble to higher frequencies. Also, the tuning of the DN-2000J gives it an advantage at low volumes, not high volumes. If you listen at higher volumes, first of all, don't --- it's unsafe for your ears. Always listen to volumes that are as low as possible.
 
Being an extremely low impedance earphone, the DN-2000J will inherently be picky with sources. If you want an earphone that will sound great on all manner of sources, the DN-2000J is not for you. Ideally, you will need a source amplifier that delivers high current and quick voltage swing, and great THD+N as well as IMD performance. The low impedance of the DN-2000J will be a definite strain on amplifiers. However, this does not mean that you will need a very expensive amplifier. You will just need to look around for one that's most suitable. For example, I find the FiiO E11K (A3) is the one amplifier that I feel pairs best with the DN-2000J when it comes to taming treble hotness.

 
Went to give it a try yesterday and to my great surprise, in stock form, I literally couldn't hear any bass at all, from the X3 to Cmoy. Thought it was really weird, and was thinking what all the hype was about. Then I plugged it to the X3 directly and it was a little better, Same for the Z3. After that I tried the bass ring and it improved the response considerably. Following that I put on the thickest tuning ring and finally got the bass to a nice level.
 
At first I was wondering if it was an impedance mismatch issue but then the final combination worked well with in all source combinations. Could it have been more of a sealing issue than impedance? Need to spend more time with it but the Treble was still just a *bit* hot for me however.
 
At the time of my demo, the 2kJ had been burning in for about 30 odd hours.

Anyone with spinfits or spiral dot tips can give me a impression with them on plz and thank you
