But even then we're talking about much longer than 20 years.

I see... Seems that TH900 should be very durable, since I gonna keep this headphone forever because it's the first well-made headphone in my collections, I like it much more than my HD700. It's a piece of art!

So far, Luxman DA-200 is the best DAC/amp combo for my TH900 i have heard. The headphone output is really amazing and the integrated head-amp is powerful enough to drive the TH900. I like it even more than the Zodiac Gold because it's cheaper than Zodiac Gold and i can get the sound in similar level as the Gold. I have ordered it and will post my impresions after couple weeks.

Hi,i just want to confirm that my version of headphones is the same as everyone else.What i find a little odd is that the space in-between the cup and black metal hinge that holds it on the right ear is naked metal color (e.g. not painted black) as oppose to the left ear. Is this suppose to be like that or they forgot to paint it:)? It has an early serial number and does have a swivel problem that was discussed before.Doesn't bother me but the color thing looks odd.I don't think it meant to be so you could see a metal.Looks much better with that middle part painted black.

The swivel problem is definitely a problem, but the difference in color you're talking about is normal, supposed to be like that. I was once concerned about it like you were, but Fostex made it clear that every TH900 are made like that.

Songmic, thank you very much,as far as a swivel goes i don't mind it,since they fit ok on my head,now my thinking goes:if further serial numbers improved on a quality of HD-800 and T-1,maybe at some point i will regret that i got an early series:) But the smile on my face is worth it after 2 weeks of burning-in.At first by the way i was dumbfounded at what i got,especially in the mids department.Sounded that mids didn't exist straight out of the box ,neither the soundstage.Almost sold it but decided to linger and now i don't regret a bit.

You've discovered the two mysteries of the TH900 lol.

 

That ring you're talking about is actually a coating of metal leaf I believe, rather than an exposed surface. The instruction book mentions it, so it's definitely intentional. Not sure what purpose it serves however (since the channels are already clearly designated, and the material can't be felt...). Perhaps it was a means of designating the cups before they were installed, since the "L" and "R" are on the frame.

 

The swivel problem however is not supposed to be there, but a lot of people including myself seem to have it, and it's not really a big deal for me personally. You could always get Fostex to correct it, but unless you live close to Japan it's probably going to be more trouble than it's worth.

 Did see that on my 900's as well this weekend, the two different colors, I almost drew the same conclusion instantly, like you said.. to separate Left and Right. =)

But for R10, it has been experienced 20 years history but still works perfectly fine now.  So i am really confusing about the life of Bio-dynamic headphones now... (sorry for my bad english :P)

Just to back track a little,  is there any real evidence to back this claim up?  Could the idea that these bio - cellulose drivers be more prone to failure in years to come?  Will the TH-900s longevity be an issue?  What are your thoughts?

 

@archeryc where did you learn of this supposed weakness?

 

This will be a future purchase for me more than likely and I would like to think it would be a long term investment .... so to speak.

i found this from a chinese headphone forum, some people there complain about the quality of the bio driver in Sony e888 earphone. Not sure whether this can apply to the TH900. But IMO the TH900 is much more durable than normal headphones and just like the R10, it can last long more than 20 years.

These http://www.head-fi.org/t/469760/fs-sony-mdr-e888lp-new-earphones !!??

 

I' had them for many many years (and didn't have any problems with them - think I finally thew them out when I moved apartments earlier this year). Anyhow, if the R10 was built the e888's I'd be rather disappointed :p. Vastly different in manufacturing costs I'm sure.
