It should work fine
Just noted in their feedback there's a couple negatives from people saying they're selling fake samsung cards, not sure about this brand though.

Ooh cant wait for your review.. where did u buy the impedamce adaptor?[/quote][quotee="Takeanidea" url="/t/630288/the-new-iriver-ak100-a-high-end-dap/7395#post_9916706"]I don't think it reduces the impedance. I really don't know the science behind them. Ask Rin about how it works.
I've got a stock AK100 coming and I have a plug in impedance adapter for my Etymotics ER4Ps that changes them to 100 Ohms. They can be plugged into any IEM. They go loud enough to give me a headache on my Ipod so I'll get back to you on how it changes the sound on my lower Ohm W4rs XBA4ips and Monster Inspirations etc.For me , I have a Slee Voyager Amp and big pockets so I can't lose
An impedance adapter changes the impedance of your headphones - not the output impedance of the device. FYI, this will not fix the problem with the output impedance of the AK100.

So what is the ohm ratings of the iem's and phones that headfiers have found work well with a stock AK100? Because all of mine can be tried as at least 100 0hm phones. I shall try anyway and see what a real world result brings, it can cause no harm.
Bear in mind I'm no scientist but I know where the University is, I drive past it all the time -:O)
The issue with the high output impedance is only because it makes the AK's output impedance so close to (or higher than) many of the earphones out there. If the earphones can be converted to higher impedance this would put more distance between the output impedance and the load which will rectify the problems, however, I am not sure how the adapter actually works. It may be attenuating the volume to be "like a 100ohm" earphone by bleeding off some power rather than actually creating a single load of 100+ ohm.
My understanding of these sorts of adapters is that they actually raise the output impedance, not the load impedance (to attenuate volume). Of course, I don't know what wizardry Etymotic might have used so I can't comment on their specific adapter and look forward to Takeanidea's findings.
I sent mine after Vinnie suggested that there's actually no issue. Just declare it as a portable amp or something and if they ask you can say it hasn't got batteries installed. Strangely they don't seem to check!?
That said, it the adapter really works the it'd be my preference too.

hi guys - does anyone know if the AK100 supports use of cable remote so the volume control and track skipping & stopping functionality? thanks
