The ER4-P's need a small adapter that changes the impedance, or ohms, to make them match the amp--the ER-4S are made for an amp without that tiny adapter, but don't work as well with a self-amped device like an iPod.
Thanks for the recommend and solid review. I think I'm leaning towards the ER4Ps as well. The majority of recordings I listen to will indeed not be binaural, and the response for these earbuds will more than allow for accurate binaural and normal listening. After taking a look at the frequency response graph, it's quite astonishing how flat it is for frequencies up to and around ~2000Hz. After comparing, many graphs of audiophile grade speakers, the ER4Ps offer tremendous bang for the buck. The online reviews are all very positive as well.

What type of adapter is required for matching the impedance of the amp? Does this come with the ER4Ps, or is it a piece of equipment that needs to be purchased separately? Does the Bithead have this functionality?

This will be at the top of my list of things to try! As a person that's only used earphones that have been pre-packaged with portable players (Cassette and CD), I can't wait to experience the difference that only good headphones/speakers can deliver. It's funny, but I've always known the craptacular quality of the headphones that I've been using, even with no other frame of reference. Audiophalea is in my blood .

This is precisely what I'm suggesting, and yes, it would be awesome . I'll be looking investigating this quite diligently when I actually get the N810. For the time being, though there's too little documentation lying around, so it makes investigating quite difficult. However, if the Total Bithead can indeed take audio from the N810 easily over the USB , and other home-stereo devices can take audio from the N810 via USB, the difficulty in discovering line-out and getting it to work would not be as large a priority. I would likely just ignore discovering the potential line-out functionality altogether.


About the Bithead, it really shouldn't need proprietary drivers on any modern system. It's just an outboard DAC (digital-to-analogue converter), which is one of the most simple and standard kinds of chips out there. It doesn't need a signal sent to it in any special way; it just receives the audio stream digitally over USB and the DAC converts it to an analogue signal. Done.
This is an exciting revelation! It's even more exciting considering that the Bithead has it's own power supply, increasing plug-free listening longevity, and making it more likely to actually work in the first place.

It would be interesting to pipe a wav file through the raw USB device and listen what comes out the other end. Since I'm planning on getting the Bithead (or similar mobile amp), I'll be able to test out a couple of configurations. Additionally, it would be great for home audio as well, as the N810 could not only be a remote, but also the device actually supplying the audio.

I'm sure there would be a bevy of people that would appreciate any solutions we could come up with. Great work Bex!

Of course, after USB connectivity, comes WiFi streaming of audio to a capable server attached to the stereo. The only thing better than hooking into and playing your tunes from the N810, is doing it without hooking in! This solution should also be possible (and quite easy). I *think* that MPlayer can pipe wav data out, meaning that a socket connection to a media server that pipes it's data to the systems audio device, *should* allow fairly simple wireless audio streaming from the N810. A nice interface (possibly a configuration of existing media players), and you can play crystal-quality tunes from your N810 just as easily as playing them on the actual device; something well worth getting working! This is something I would like to work on.

YARR!
