Question about IE6/IE7/IE8 and other dynamics

post #1 of 8
Thread Starter 

  There's something I have been wondering for a while that I'm curious about.

 

For BA IEM's, price is usually reflected in the number of drivers.

For example: Shure 315/425/535 price raises was the number of drivers increases

Same with Westone 1/2/3, SM1/SM2/SM3,  UE 600/700/TF10 etc...

 

    So what about the Senn IE6/IE7/IE8? I understand why the Shure 535 is more expensive than the 315 and 425, mostly because

it has more drivers. But what is it about the Senn IE8 that makes it retail for almost $300 more than the IE6? Both are single dynamic drivers, and unlike say the Final Audio Design's dynamics that have different metal housings, they don't seem to be built with particularly different materials.

    So my question really is, if more drivers, in general, reflect in more expensive BA IEMs, what's different about the drivers in premium dynamics?

 

Thanks

Simple rule is better sound quality and tuning to offer more from the same driver unit. Sound quality improvement between IE6, IE7, IE8 is the main factor of price difference.

Thanks, but that is exactly why I asked the question. What does special "tuning" mean and "sound quality improvement." In the case of BA earphones the amount of drivers makes sense but I wonder what exactly does "tuning" mean that can make such a difference (and price increase) between different dynamics, such as the IE6 and IE8?

They basically make the best dynamic driver they can, then cripple it and place it in a different housing and sell it as a lower end model, while the flagship commands a premium. This happens a lot in the technology business when multiple models are released at similar times.

You seem to be assuming all BAs cost exactly the same and all have the same quality and performance, so the only variable is the number of drivers used.

 

That's quite wrong.

 

The idea that dynamic driver iems should all cost the same because they all have a single driver is completely wrong as well. 
 

Maybe you should start by learning more about the many kinds of BA transducers and then, later, you can learn something about moving coil transducers.

Excellent questions and responses.

Kunlun, I don't think takoyaki7 is assuming that all BAs are the same at all. Rather, he/she seems to assume that for a given series of IEMs using BAs (e.g.: Westones UM series), more BA drivers = higher price. This assumption holds true as far as I know.

 

takoyaki7: perhaps the premium on "top-tier" dynamic IEMs can be explained from two angles--different drivers, and different housings. 

  1. Different drivers. I don't know if Sennheiser uses different drivers in its IE6, 7 and 8, but let's assume for a minute that they do. If so, then this would be similar to Audio Technica using different drivers in its ATH-M30 (40mm) versus its M50 (45mm). Both Audio Technica headphones have 1 driver per earpiece, but the use of different drivers in each headphone leads them to price each model differently.
  2. Different housings. Now let's assume the IE6, 7 and 8 use the same drivers, but in different housings. This would be similar to beyerdynamic--the DT 770, 880 and 990 apparently share the same drivers (see this thread, from post #11 onwards). However, just like how the same speakers perform differently in different rooms, the same headphone drivers sound different when the housings are changed. While the materials of the housings alone may not warrant a price difference, I think what we pay for (at least partially) is the R&D to find out which housings sound best with which drivers.

beyer's drivers are fundamentally the same, but they add or take away materials to change the sound. The DT880 has a net and a piece of velvet or something, which decreases bass and highs. The DT990 has neither. The DT770 I'm not sure about.
