CHART | Balanced Armature-Based In-Ear Monitors & Technical Characteristics

post #1 of 128
Thread Starter 

NOTE: Please PM me before requesting to be a contributor for the chart, or else I won't know who you are just by looking at your e-mail address.

WANTED: Assiduous individuals to help add to and perform maintenance on the database! I don't pay as much as Apple (in fact, I can't pay you at all!) but you'll contribute much to the community in the process!

 

A while ago, I was thinking about the major threads here in the portable forum, and what the next step might be. I thought about a project that anyone could contribute to, and thus went to the cloud and the wiki concept. Google Docs is a widely used web application that can allow cloud-based editing from multiple sources and be published on the web in real-time. I thought, "Why not create a chart that can give members all the major specifications of IEMs at the tip of their fingers?" and thus went about creating a chart that would possibly allow for such a concept. Currently, the chart is only designed for balanced armature IEMs and their technical details, but the project can easily expand to other parameters as well.

 

Below is the current, rudimentary version of the chart; as you can see, I don't have most models listed, but you all can get the idea of what the concept is. I'm in the process of recruiting various members that I know have significant knowledge to contribute, and have them on as collaborators/editors, but the goal is to make it so that anyone with the desire to contribute to this chart can do so. As this idea is in the very nascent phase of its conception, please let me know what types of improvements I can make to the workflow and format of such a chart!

 

Clarification: this chart is not merely about drivers. Although that category is a large part of the chart, it is mostly there to provide people who need/want that technical information to do remolds or DIY projects. It also displays a transparency of information, where people needing this type of data can go into a chart like this and compare the types of technology used by in-ear makers around the world. This chart is primarily an at-a-glance document for people who need to do multiple comparisons at once, and secondarily also a testbed for the crowd-sourced, cloud-connected method of mining information.

 

If anyone spots any errors (I know there are quite a few), inconsistencies, or omissions, please feel free to post in the thread!

Japanese blogger 84 (http://84audio.blog.fc2.com/, http://www.twitter.com/90percentPA) also has a very similar chart, embedded here:

Very Nice, good work! I think this complements your other thread nicely!

What a great concept. As a somewhat obsessive collector and archivist of listening devices, I'm all for it!

Currently, the chart is far from complete (it will be a constant work in progress), but it has already been fleshed out considerably, thanks to the massive contributions by piotrus-g!

 

BTW, if anyone has trouble viewing the chart, or has any suggestions, at al, please feel free to leave feedback. If you're interested in becoming a contributor, please also feel free to contact me via PM!

Excellent .................

AFAIK, the first Moving Armature IEM isn't GR8 (announced late July 2009), but Ortofon e-Q7 (announced May 2009).

Wouldn't it make more sense to include the price as well? At least the MSRP IMO.

These are the types of comments this thread needs! Thanks!

Noted! Another column has been made for the MSRP...

Ooh interesting...

 

My only bother with that chart is that the 'Description' column is too wide for my screen.. I find it annoying to continuously scroll sideways back and forth, but again, I guess the main point of that chart is for a quick summary of the IEM itself, and not its technical specifications. redface.gif

Sweet! This certainly help me in quick reference when I'm ready (both monetary and lust desire) for a CIEM later. Stalking the thread.

Nice list, though a little hard to see... But I heard the JH13s uses TWFKs for a few of their drivers?

Yeah, I need to find a means of improving the formatting. As you can tell, in the way it's formatted right now, it's way too wide. I envision that it'll need several sheets. I'll work on that.

The DFK looks exactly the same as a TWFK, except that the DFK is two FKs fused together, while the TWFK is a WBFK fused with an FK. On the outside, however, the two are indistinguishable, save for the serial number. Check out the Knowles Design Guide...

I call it a day.

I really like how it starts to look, but it still need a lot of work

post #14 of 128

Sony XBA-BT75's are over ears

 

Also there's the Rooth range but I'm not certain if they are considered as a part Unique Melody or their own company (since they have their own techs and designers).
