Any comparison to a rockboxed Cowon D2 or AK100?

^ Re X3 vs. HM-602, one significant difference is their output impedance. HM-602 was measured to be 11.44 ohm, while X3 was measured to be 0.4 ohm. That means X3 will work very well with balanced armature IEMs, while HM-602 is far from being optimal. Such difference would not matter much for headphones with impedance of over 90 ohm. And human ears may or may not tell the difference in frequency response. Personally though, I would prefer X3 and avoid HM-602 if I primarily use low impedance BA IEMs.

When you have had sufficient time to play with it, I'm interested to know REAL battery life, playing .flac 24/96, please, ClieOS.

 

Cheers.

Well, just these initial impressions have me pretty excited!

When will these be released in the states?

First batch, only few will be sold in China ( about 100pcs ) to test the market. we plan to ship out the X3 to our agents in China on 24th.

 

The second batch, 1,000pcs for China market, 1,000pcs for few regions ( not decided yet, but should includes Taiwang and Hong Kong ). ETA: 5th, June

 

The Third batch, >5,000pcs for the whole world. ETA, 5th, July.

Alrighty thanks. Another question: do these support digital audio output? Otg cable?

I think there is a misconception that high output impedance is automatically a no-go for low impedance BA. That's actually not entirely true. It is only a no-go when the impedance phase (resistance across the whole frequency range) is not linear. As long as the impedance phase is linear, high or low output impedance will have much less impact in coloration.

 

Talking about HM602 - if you know how to solder, there is a simple mod that can lower its output impedance to less than 1 ohm.

Okay.

S/PDIF coax out. An adapter cable has been included, though making one is very easy as well.

First page.

 

Yes, they support didigtal output(not input) through coaxial.

 

OTG for Android so that you can use X3 as a DAC and amp? No. You can't do that. That's the E18 and Andes(not ofifical support).

I'll be curious to hear how battery life is with high bitrate LAME mp3, when you have time. smile_phones.gif

post #566 of 13310
So what can't it do? It seems like a pretty easy buy at $180.

Digital input so that it can be used as a DAC with a computer or Android device rolleyes.gif

 

Make my bed

 

Do my HW

 

Mow my lawn

 

Cook toast for me.

It can't do many things.

That will be easy, since most of my music are high bitrate anyway.

Well, I have not able to teach it to cook me an omelette yet wink.gif

Nope, already checked those things, it can do those too. Lol biggrin.gif

Thanks for your comments ClieOS. I have not heard of low impedance BA IEMs that have linear impedance phase (and I have seen many FR graphs of BA IEMs). Please kindly name them (I may like to buy a pair of those). I only knew Heir BA IEMs with high impedance.
