One of the very first things I did when I started InnerFidelity was call Doc B. (Dan Schmalle) at Bottlehead to get a little Crack. No, not the white stuff...the dandy little OTL headphone amp DIY kit. I wanted it for my measurement program, which was slow in coming, so it took a while to get around to building it.

Ah! The sweet smell of solder!

Having printed out the measurements for all 41 Do-It-Yourself modified headphones sent to me over the past year, I spread them out over my kitchen table and set to work picking the best and worst measuring of the bunch. I also picked what I thought were the coolest looking headphones. And I scrounged around my lab looking for all the headphones I might give away as prizes.

Let's see who got what ...

Kojaku - aka Sean S Posted: Mar 20, 2012 50 comments

A couple of weeks ago Head-Fi DIYer Kojaku sent in a pair of heavily modded Grado SR225i headphones. I'm not really a fan of Grados ... okay, I really dislike them, but these modded cans were very good. The best sounding Grados I've had the pleasure of hearing.

I asked him to tell his story ...

In my view, the Sennheiser HD 800 is the world's best dynamic headphone. Its imaging and transient response is second to none. (Read my full review here.) The problem is, brutal honesty can be tough to take.

Fortunately, there's a relatively simple modification to take the edge off your HD 800.

How do you attach your portable headphone amp to your player? Velcro? Big rubber bands? A hacked small camera bag?

Here's another solution ... and it's miraculous.

Some modified Grado cans have shown up in the lab. I don't know what my problem was getting to them in a timely manner, maybe it's my dislike in general for Grado cans, maybe it was the trouble I was having getting my corporate shipping set up, but I've finally managed to get around to listening and writing this post.

Oh, well, here we go ...

Kabeer - "I am located in UK, and I have some orthos. Im not sure if its very viable for me to get anything measured?"

Tyll - "I really can't spend too much money on this, so I've limited DIY Ortho testing to the U.S. to keep the shipping costs down. Sorry."

Kabeer - "Id really like to send my Aiwa to you to get measured. I think its pretty great :). Wualta wants to see their measurements too and has kindly offered to pay you the postage back to UK for them."

Tyll - "Okie Dokie. If Wualta wants to see the measurements, it must be good."

You see, while Wualta might be a crusty old curmudgeon, he's also one of the patron saints of Orthodynamic DIYers, and if he thinks something is worthwhile ... well, you just have to have a listen.

By golly, he's right on the mark again!

It's not often a pair of DIY cans comes walking in the door with its own monster branding. Not only has enthusiast 4nradio breathed life into this odd assortment of bits from previously dead or discontinued headphones, but unlike the good doctor of yore, he has fallen in love with the monster he brought to life, and given it character and personality.

Let's meet the monster.

More modified headphones came through the lab this week. scompton sent in three modified Fostex Orthodynamic cans, and Morphsci sent in a couple of Headphile.com modified AKG K340 headphones.

Quick pix, and impressions follow!

Aw geez ... I feel so lucky. I teared up a bit as I unwrapped six DIY headphones from dBel84 on Head-Fi. The work, love, and enthusiasm of this owner/modifier/enthusiast just radiated from them. I feel so privileged to have people send me their pride and joy DIY cans. It's a very special thing for me personally.

Come, let's have a look at this very personal "personal audio" collection.

In preparing my article “How Planar Magnetic Headphones Work” I became enamored of the work being done by DIYers building their own Orthodynamic cans over in the "Orthodynamic Roundup thread on Head-Fi. The blood, sweat, and tears invested in building and modifying vintage Yamaha Orthodynamics, and cans like the Fostex T50RP is simply stunning, but more striking is the sense of fun and camaraderie so clearly evident in their headphone play that I simply can’t resist trying to find a way to enter into the party in some way.

I think I’ve figured out what I can do.

I’ve had more fun tinkering around in my basement over the last 6+ years than I ever would have had wasting away on the couch watching TV. I’ve built 50 or so projects ranging from the very cheap and small to the rather expensive and large. Has it all been fun, nah, but what good journey is? If you wanna try DIY, read on ...

Promises Kept
My first post was an exercise in getting all the bits-and-pieces together to create content. In many ways this is my first real post here ... and I want to keep a promise. For years I've said I would measure the effects of the various headphone pads on Grado headphones; well, I am very glad to say finally: here it is.
