Remember that these are sold in very small quantities, not like Sony's, UE's or Westones so I won't be surprised if these are made by hand.
Suyama-san has done a good job in testing the international market with his universal IEMs. It would be sad for the international customers if he decides there's too much trouble or hassle & pull back the FitEar models to the local Japan market only. So let's try to help him productively.

I am sorry Anakchan , the reason I put this issue because I like very much fit ear 334
I want only to know why between 5 fit ear has different sound quality .no more or less
Nothing again fit ear , this critic is for better fit ear in the future.
Because I love my fit ear 334 very much , fit ear 334 is the best SQ from all my iem I own.

I know you live in Japan , BY I do not know

I take it back the QC issue for fit ear 334 and apologize to Suyama San too
Your product is excelent
I love Your fit ear 334 , please do not take My critics as personal again fit ear

I hope this case is close in this page and I will keep for my self about this sq different.
And I apologize to all head fier friends if my word not so good because of my limitation in English

I have read several places online that the 334 is " hand made in Japan, in limited numbers". Surely handmade items can't be identical, exactly that is the difference between man and machine, and this should be appreciated. Suyama-san is my hero smily_headphones1.gif

I believe those are hand made.

I listened to 2 pairs of ToGo334 (a demo ones and mines) so far and didn't notice any difference in sound.

Same here.smile_phones.gif

Sorry, I don't really understand what that means redface.gif Couldn't frank just remove the connectors from the stock fitear cable and attatch them to his wires or something? Sorry I don't know much how cables are made. tongue.gif

I have to say they are dead even as being my favorite. As far as SQ I think the Miracles are clearer and the 334s go deeper, if that makes sense.

 

The deciding difference as to when to use one or the other is environmental. When using for a long, uninterrupted (not having to take out), and desiring a complete isolation setting its the Miracles. If I need to pay attention to my surroundings and remove every so often the 334s. Therefore for the time I've had both, owing to my circumstances of use, I've spent many more hours with the 334s.

I think the issue here is that the sample size is not very big, and that has to do with the nature of the product, being a low quantity, luxury product. If it were a very obvious difference between one batch and another batch, there would be a definite issue, but even 5 samples isn't large enough to really constitute anything that would prompt a change in their QC procedures.

 

The second is that A/B testing isn't really reliable, even when tested on identical rigs. I don't know how obvious the differences you state are, but they may very well fall within the testing parameters of their QC. I have no idea what the procedure actually is, but I presume that FitEar matches their drivers first, but testing the individual performance of their drivers, and to select drivers that come within their channel matching tolerances, +/- 2 dB or whatever it is they stipulate. They then need to position their drivers around that specialized triple bore nozzle and layer the acrylic down to secure the drivers. This process should be highly repeatable. It's possible some dust gets in between the sound tube and the damper, or the drivers aren't completely secured, but these things aren't likely to happen.

 

Below are pictures of the FitEar assembly process; you can see some potential issues during the QC process, such as the clay sealing around the coupler and the earphone not being a hermetic seal, or the dust not being completely vacuumed aways by the suction duct during the drilling and finishing process, or the assembly process not going well, but these things are unlikely to happen, and I'm sure the IEMs undergo a final test before being packaged and sent off. It's difficult to say whether this is a QC issue or whether it is just due to natural variances in the performance of the drivers/electrical components, but that fall within tolerances.

LOL... no, the connectors don't work that way. The stock FitEar connector is made with what is termed an 'overmold' process, where plastic is injected into a set mold all around the wires and the pins to secure and stabilize the entire thing. Most DIY connectors are already molded, and have outcroppings to allow a user to solder their own wires onto the connectors. This is not possible with the overmold process, unless you preserve a part of the original wire, and solder wire-to-wire, as opposed to pin-to-wire. That's not an ideal way to make a cable, and I don't think (certainly hope not) Frank would make a cable in such a fashion. So, either he takes a ready-made DIY connector, which is currently made only for the Sennheiser HD600/650/25 and not of compact dimensions needed for FitEar IEMs, or he'd have to take measurements of the FitEar overmolding and the pin lengths/diameters and send those dimensions to his injection molding company. That'd mean either one of two things: (1) he'll charge you a lot to prototype and overmold such a connection, much more than normal, or (2) he intends to use these measurements to produce an entire line of cables for FitEar.

Thank You For Your explanation
I Am very Happy With my fit ear 334 , because i become excelent units .

The way fitear made they connector is they solder the wire to connector pin and mold everything together in plastic/acrylic. It's almost impossible to remove the cable and reattach a new one without destroying the connector.

 

PS. I just notice that the left side of my connector have a crack T^T. I probably have to order a new cable soon.

Yikes, that is the first crack I've seen in a FitEar connector. Congrats?

Yeah, It's been less than four months since I bought 334. I just order the replacement from fujiya-avic. It should arrive in Sendai sometime in Monday. I consider the 000 cable but they are out of stock, so I just order 001 cable. T_T

post #1482 of 3832

guys,I just found how to get the best sound out of these.

You use the smallest tip, then insert them deep deep in (no vacuum sound at all).

And the result is simply mind-blowing.

Bass is at a level higher than the HD650 (clearer)

Sound stage is huge, 3D.

resolution is on par with my HE-500 (planner-magnetic !!!)

It has always been good, but this is the first time I found them to be perfect.

Yes, fit is the most important thing with this earphone. If you don't achieve perfect fit, sound is meh. Achieved, it is phenomenal indeed.

This is what I've been doing pretty much since I got them. If I smile or eat it breaks the seal and I lose all bass and isolation but that can be useful sometimes as well (like when you want to hear announcements on a train, you just smile really hard biggrin.gif)
