Try Adafruit's USBTiny drivers for Win7. I haven't had success with Sparkfun's drivers or workarounds on Win7 x64. Drivers are the biggest battle.
 
Switch C5 on after connecting the USBTiny. Then from Arduino, use File-->Upload Using Programmer. Its power light will remain off, but that supplies +5V power to the Atmega168.

Argh, I'm still having a hard time getting the Pocket AVR Programmer to communicate through the Arduino software.
 
SparkFun finally updated the webpage and now contains the drivers provided by the Adafruit website you linked.
 
I'm using Windows 7 64-bit:
  • Download the drivers as indicated above
  • Rename x86\libusb0_x86.dll to libusb0.dll as stated in the README file
  • Run installer_x86.exe
  • Put the boards.txt file from the C5's .zip folder to the arduino\hardware\arduino folder
  • Connect Pocket AVR Programmer to computer
  • Connect Pocket AVR Programmer to C5
  • Turn on C5
  • Open the Arduino software
  • Open c5_v100_MasterFirmware104.ino
  • Select the C5 board from Tools -> Board
  • Select USBtinyISP from Tools -> Programmer
  • File -> Upload Using Programmer
  • This error is encountered: "avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)"

John- are you lining up some retailers in Japan or Asia?

 
We have several distributors in Asia, including two in Japan.

Your steps are correct, but you still have a driver problem. Which did you download? The link points to Sparkfun's drivers, as well as to all of Adafruit's drivers. I believe I'm using these for Win7 x64:

Yup those are the drivers I installed. I'm using 64-bit Windows 7 with an Intel processor and thus I used the "installer_x86.exe" file.
 
In the README file it says:
Quote:
X86 ONLY ARCHITECTURES:
  x86\libusb0.sys: x86 32-bit driver.
    Installs to Windows\system32\drivers\libusb0.sys

^ I don't see that file in that folder so maybe that's where I'm having problems.

I've already contacted hifiheadphones about stocking JDS, we'll see.

 
that's great news.
 
if they could over it for a US type price i would order one C5 on the spot !
Love to see a comparison Between the C5 and the Fiio E12., or perhaps do one as soon as my Beyerdynamic T5p..
 
$189 is €147. ..and the Fiio E12 is €120.. 
The difference is not that big..But if Customs and other crap needs to be added ..
Than i'm afraid you would be looking at a to great / big of a price difference.
i mean €20 -- $25 more i can explain as being better or just opting to a different clientele.
 
But i have never heard anyone out there do a sound comparison with a good set of headphones.
Like the Beyerdyanmic T1 or T5p…
 
Well if hdphns is willing to go for it at a good price ..And they give there usual 30day money back period then i could just get both and write a good review explaining the Sound difference between the both models.. Witch i consider to be competing (as a product line) with each other..
 
But hdphns could also say that they wold order one for me and that the 30days won't apply or so they told me..
 
Well i will wait and see..And perhaps if wanted drop a mail :wink: ?? But first i would wait and see what they decide..
 
Really sum times i just think to leave ICT and start a internet shop ..
Specialised in US products ..For the EU !!
i mean i think i'm not that special but apparently i seem (lately) to always get my products with the MADE in the USA label on it hahaha… Last time it was shoos from Keen no it's an amp!!

To me the C5 sounds like a mini Objective 2, or a typical, what people call "solid state sound." The E12 on the other hand is what people call "more musical" or "tube-like" in sound. In other words, the C5 is more true-to-the-sound and detailed, whereas the E12 is coloured to sound more like a tube amp with a warm sound signature, good texture, and laid-back treble response.

Personally, I never find E12 to have a tube like sound.

Well not tube, tube sound, but it's got the warm tilt to it with a laid-back midrange from what I can hear.

 
Tube sound to me is all about lushness, and I didn't hear that in E12. Didn't notice the mid is being laid-back as well.If anything, I find O2 more laid back in overall presentation. In fact, I'll say C5 is more forwarded than both O2 and E12. Well, perhaps forward is not the right words - I think C5 has shallower depth, kind of the opposite to E12.

Depth, yup, the C5 kind of lacks in that area. After approximate volume-matching the O2, C5, and E12 with a 1 kHz sine wave, I still find the E12 to have the most laid-back midrange. Maybe laid-back isn't the right word.
 
Listening to music, I feel that the C5's midrange is more forward than that of the O2, which makes it more engaging for me; it makes me want to sing along with the songs. The E12's midrange seems more distant from me and it's not as engaging; it's more relaxing to listen to, but I don't feel involved in the song at all, I feel as if I'm just casually listening to music. The O2 is in the middle of the two; its midrange is mildly engaging for me, yet relaxing to listen to too; I feel in the middle between the two.
 
Oooh wait I think I know what you're saying now, maybe. Between the O2 and E12 the E12's midrange does sound louder than that of the O2; is this what you mean by forward? I think I'm mixing some terms here..... >_<
E12's midrange does seem more forward in this sense, but it doesn't sound as realistic to me and is non-engaging, hence why I said it's "laid-back". The C5's midrange in comparison is louder than that of the E12, being the most forward in this sense? The C5's midrange sounds more like the singer is singing to me so that quality of the midrange is why I said it's "forward". From all of my experiences with tube amps, the midrange seems to take on the "laid-back" term I use, where the midrange gets less engaging and more relaxing-sounding. Sorry for all the confusion!

I don't know which, if any, of these, is colored to sound a certain way.
 
I do know I enjoy listening to the E12 - it's very dynamic, and does 
have a softer high end than the C5.

I have both the c5 and e12. I would say the c5 is noticibly brighter and more fatiguing than the e12. Overall sound is excellent.

I can listen to the e12 for longer periods of time because of the softer highs and sweet mids.

Yeah I agree with you there.

I've been using the C5 with the V-MODA M-100's (with my portable rig) and K 701 (gaming and movie-watching).


I love the k 701. I assume those are bright with the c5? I dont have a pair, but have used them and i always found them like the er4s, where they sound incredible, but a little bass light... How much flatter does the bass boost make them in the lows? Or does it technically overdo it a bit?
