FiiO E07K ANDES Review and Help Thread - Page 3

Some of the biggest changes are a better software and UI with eq controls. It also uses Fiios new headphone jacks (longer lasting and durable). For me they were very tight when i first got them. I literally had to use strength to put my jack in and out of andes. It became normal after about 5 times. It also uses new op amps and also a new usb decoder.

Check it out.

Generally it is kernel dependent already as you need USB OTG support. The phone hardware wise needs it and its kernal software needs to support digital audio output through its USB port.

 

Update:

Only some IEM's exhibit noise while others don't. 32 Ohm portable headphones don't have any and some 16 ohm IEM's do while others do not.

 

Your mileage may vary.

I was just putting that out there. The noise is still prevelant ON SOME.. But of course you have more IEM's than I so your vote on this part would be interesting to note.

 

I don't get noise on all my IEM's(they are not sensitive). 

 

I don't see this to be a problem unless you use low impedence IEM's for it which some will do. I think it should still be noted none the less.

 

I have used all gains with the IEM's.

@Everyone

I am just noting that the Andes may have some noise for IEM's that are near 16 ohms and or are very sensitive. For all other types of headphones, there is no noise with it.

As long as the PMP has a headphone out jack. The E07K can be used with it. However you will thus be using the amps of the first PMP along with the two op amps in the E07K. The DAC will not be used.

 

If the PMP has a line out like SOME(not all) Sony's have or like an iPod, then you can bypass that devices headphone amp(s) and just use E07K's. DAC will not be used.

 

If a device supports USB OTG and has software kernel support for digital audio output or if it just has digital audio output then it SHOULD (not always) be able to use both DAC and amp of E07K. But WARNING, be careful. If the powerdraw of E07K is higher than device supports then it will not work. The above posts on the Samsung being able to do it or not is on this problem as well as which kernels currently work. 

Android devices are far and wide, are you going to release a list of devices that are compatibile with specific kernels or OS? Or will E18 be compatible with all Android devices that have USB OTG support without care for kernel or ROM?

The standard was Nexus I believe  which was Google's own house phone. At first they had a lot of help from Samsung in designing it. In the second version they more or less made it themselves. And then Motorolla Mobility was formally bought and aquirred by Google. So let's hope we see a very interesting new Nexus.

 

Yeah I was going to guess that the E18 would need to work with phones that support standards and also with software that allows it to output that signal. The people that buy an E17 or E07K asking if it can be used with their Android phones all have phones with those abilities anyway (unless they didn't know) so that is fine I guess.

 

Your new E12 bundled band looks great. I am guessing you need 10mm bigger due to the E12's "larger" size.

 

These units are heavily used with iOS devices and iPods. Would it ever be possible to design a band that not only straps well but is about half as thick? I will post an orientation part in my review and what I think are best strap positions but I still get some blockage. Just wondering if it would be possible.
