post #271 of 4277

I had bought and returned the XBA-4 when it was first available at the Sony store. That was at its maximum suggested retail price. I could not justify the price pursuant to what I was hearing. But in talking with the friendly personnel at the store, it was divulged that one salesman bought the XBA-1 for his personal use. His discount was hefty and he chose that out of the entire set.

I've just emailed logitech Australia about their ridiculous price difference compared to US market. Let see how they justify it (or at least if they even will reply to me).

I will keep the Australai folks updated.

For once the NZ price are much lower than Aussie. It is 600NZD here which is about 456AUD

If this is indeed going to be exclusive to Apple Store for a while, then there is no way the price will drop.

 

Only when Amazon etc has access to it, then the price will become competitive, until then, I think I'll buy GR08 first if it comes out before UE900 price drop :)

I wish they come out clean on how they decide which region gets what price.

Scabbing.

edit: so I realize it's not the number of drivers that's the issue (plenty of universals with like 4 drivers) but the fact that the two sound tubes from the drivers go all the way into the bore that the tip fits over.  Any sonic reason for doing this rather than merging the tubes before the end bore?

 

 

From Westone who can explain better than I...

Dual Bore
Typically, multi-driver in-ear monitors have a single-bored sound port, meaning the output from each driver will acoustically sum inside the earpiece housing. With Westone's Dual Bore technology, the high and low frequency sound components are individually channeled through two passages in the sound port. This allows high and low frequency material to sum within the ear canal, emulating the more natural phenomenon of live acoustic summation. The result is a more convincing transition between frequency ranges and is audibly more natural.

 

 

Spyro would have the same issues fitting the SF 3 but the SF 3 is not dual bore being a single driver. So, dual bore is really not his issue.

 

 

Like with my CX870, 4mm tube size with 3mm bore is my minimum. The 2mm usually  fall short in overall stage size. That extra 1mm or 2mm can translate to feet of perceived image size. All other factors equal of course. Also depends how important having the biggest over all image size is to a person.

Really think they'll have a half off sale this coming Black Friday? smile.gif It would be great but most likely next Black Friday.

Dafuq?  I didn't know I had two tubes sticking in my ear piping low and high freqs when listening to live music blink.gif

I don't see two tubes on W4, but for es5, there are really two tubes going out from the ear tips.

The W4 isn't dual bore...  That's why you don't see it for the W4 XD  It's a single bore. 

post #281 of 4277

Whether dual or single port is better at the tip is very debatable. Sounds from different frequencies combining at the ear canal is an odd description of more natural since sounds don't do that in free air. 2 tubes have the advantage of separate acoustic resistance but it's not proven whether joining them into a single opening or not thereafter is worse or not. There's certainly a lot of rationalizations on headfi as to cause and effect.

Correct,

 

I was thinking like that but of course, in the end, the sound is combined together when it hits our eardrums right ?

 

so it is sounds like a marketing gimmick to me.

post #283 of 4277

Well I don't think it's a gimmick so much as a way of tuning the earphones more finely. I don't know what it has to do with separation, etc. but I notice on my TF10s that the filters on the two bores are different colors; my assumption would be that they are different filters for the upper registers and the bass, or the lower and the treble.

2 or more bores coming away from individual drivers makes sense but how many end up at the end and where/if they join is the issue. I'm sure either combined before the tip or seperate at the tip can work if tuned for it.

+1 The bore thickness and length can have different resonant frequencies that can fine tune a sound a bit as well.  There are other things as well obviously.
