Sony XBA-H1 and XBA-H3 Hybrid Dynamic and BA IEM - Page 118

post #1756 of 3252

I don't have any problem with the sound without the tape mod, but boy...this is the most awkward-to-fit IEM ever, TF10 feels like a cotton wool compared to this, I can't even get it to stick in my ear, let alone getting a seal from it, no matter what size/kind of tips I use, it just won't stay in (tend to angle down, and any head movement will lead to it sliding out) - I need a long and large silicone tips to be able to push it in deeper, something sized like the Westone true fit silicone - yes, I do have a large and deep canal, hence why I can't really use GR07 either :wink_face:

After long Time i never heard My sony H3 , since One week i have many My portable amp and Dap to pair With Sony H3

Sony H3 With :

HiiSound Studio V 3rd Edition : not so Good Synergy , bass Boomy and bloated to The midrange and High is roll Off

AK 120 Titan + IBasso D12 : very Good Synergy but still not teh best what i want

Tonite i have tried like below :

Source : iPhone 5s
Dac : Cypherlabs Class Solo -dB 2,00 Vrms
Amp : Alo Continental v2 Tube amp
Cable : mini to mini Crystal Cable Dream Line series diy
Lightning to mini USB cyoher Labs Stock cable

High: now sound more Crisp than before , very clean and Clear , not like before so roll Off
Mid : very sweet and natural , not like before so muffeled
Bass : very Good basa impact , very clean and Clear , better bass Speed and The important Think not so Boomy
Or bloated , This surprised Me , i Did not expected that My Sony H3 at The End has so kind OF bass
Separation : very Good , not like before not so Clear
Soundstage : now Wide and very Good Depth , not like before so narrow ,

Overall:
Sony H3 need to Find very Good Synergy With dap or amp or dac
I was so frustrated After i tried out The box In. December , less than 20 hours i give Up put In The box .
With This set Up really very surprised Me , very detail , very Good clarity , very sweet and Clear mid , mid has a bit sibilance doesnt disturb Me , The bass is very Good In detail and not so Boomy or bloated , i never believe that now i can match set Up For sony H3.
Before i want to sell My Sony H3 , now No more i Will keep it biggrin.gif

IMO

"Poking a hole with a thin needle is definitely recommended to prevent driver damage."

 

 

I was wondering about this as well. In your opinion if the holes are taped over completely with no pin holes how long would it take for any damage to occur and exactly what would cause the damage ? Air pressure? Also if only a tiny pin hole is made, could damage still occur from the pressure?

 

Thanks

I did the tape mod with a small hole. Mids and highs are clearer but still vocals sounds distant. Really leaves me wanting more to get the kick out of music.

Personally, I don't think there will be driver damage. The diaphragm just go back to original position quicker and moves less. Anyone can explain how the logic behind driver damage? ;D
post #1761 of 3252

Well, the pinhole recommendation comes from a guy who knows a thing or two about IEMs. To me it's logical that higher damping puts more stress on the driver, so I'd think that damage is possible but not inevitable.

post #1762 of 3252
It will be interesting to know how exactly it can damages the the driver. Coming from someone just like that will just keep us guessing >.<<br />
From what I know about speakers, which dynamic drivers works similar way. Taping it up won't increase the stress as your iem won't increase the bass electric signal to achieve the same bass prior to tape mod. In short, there's no electrical signal change thus not causing the diaphragm to over extend which could result in driver damage.

maybe I will start a thread on this. wink.gif
post #1763 of 3252

The electric signal will obviously remain unchanged, but don't you think that increased resistance against a driver's extrusion force might put more stress on the diaphragm?

 

Jm2c. I'm no engineer or scientist, but that would be my layman's take on the matter. Anyway, since I have no way of contacting Rin atm, maybe you should really start a thread in the sound science forum if you want this clarified. Until then, the pragmatist in me will continue to poke pinholes into his tapes, just to be on the safe side... ;)

Saying whether such a mod will destroy the driver or not is like saying whether a hole on the body of a moving vehicle will destroy it - obviously it is largely depends on what kind of vehicle we are talking and what kind of condition it is in. If it is jet airliner 10km in the sky or submarine under 1km of water, then yes. But if it is VW Type 2 van doing 20mph on country road, then no. For the large part, I don't think a tape mod will incur enough stress to the diaphragm to damage most headphone, at least not without some fairly insane amount of SPL involved. In that case, stress caused by tape mod will be the last thing I'll be worry about. Of course, there might be some rare case when damage does occur - but for all the mod we have done to headphone in the forum, we would have seen a lot more report of damage if something as simple as a tape mod does incur damage very often.

Basically by covering the vent more air pressure is placed on the driver. This doesn't mean it guarantees damage, it just has the potential to do so, but there is no way to be certain as these kind of things haven't been tested in controlled settings. 

 

There is no reason not to place the pinhole though, it will improve the subbass while still taming that midbass.

Let it burn in for awhile and it will improve a little bit more. It made a difference to me. In the mean time try to cut thr the bass a little bit around 150 hz with a fairly wide bandwidth.
post #1767 of 3252
I have it for a month. Should burn in pretty much already. Maybe I will just seal up the while port.
post #1768 of 3252
Can someone post a picture of the mod for those interested to see?
post #1769 of 3252

Any suggestions for tips beyond the Sony's that come with it? Just wondering if any of my fellow XBA H3 users have recommendations for tips other than Sony. 

 

Thanks
