I use them with my Fiio X5ii, which drives them great. Much more than enough volume, great sound. I also use them directly from my iPad. Volume gets loud enough for me, though it does have to be turned up pretty far for higher level listening. If you like your jams really loud, or if you have a...

Hey riversub, I haven't heard the PM-3s, so I can't give an impression, or say what you may be missing. I ended up getting HD650 headphones. They are fantastic, I can't get enough of listening to them. I really like the large diameter and soft pads. They are light weight and supremely...

  That case is for the first gen (second picture shows the first gen X5).  

    I think he means that the iPod Classic has a lot of lag.  I'm guessing this because of the "Probably more snappy than the iPod Classic" part of his post.

  I used an X5ii, so I don't know how closely it relates (you said X5, so I'm assuming first gen).  I listened anywhere from 30-50 most of the time.  I cranked it up to 60-65 briefly a couple times, but didn't keep it there long.     If you turn them slightly while they are in you ears it...

  I don't doubt that.  I was just curious what electronics would be in the cable.  

  With the sd card in the computer (or the X3ii connected with the card inserted) right click and move the folder to the recycle (called "trash" on the Mac correct?).  Then, with the card still connected, empty the trash.  This will delete the file for real (rather than just marking it as...

  I see.  The QC25 cable doesn't have anything like this.  It's just a cable with a standard (2.5mm) end.

  When you remove a sub-folder are you dragging and dropping, or are you deleting the folder? 

Well, there is no internal memory, so that sounds strange, if not impossible. How are you removing the songs? Do you take the card out of the player, or are you connecting the player to the computer with the card in the player?

My review is up!     http://www.head-fi.org/products/fiio-ex1-nanotech-titanium-diaphragm-in-ear-monitors/reviews/14334   The EX1s are on their way to the next participant.

  Could you elaborate on this?  I've seen this claimed several times, and I'm wondering what "electronics" Bose puts in the cable that interferes with the signal.

As for which one I would pick, I already have picked I suppose. I bought an X5ii recently. There are amps in both. I can't find output specs on the Sony, but if I had to guess I would guess the X5ii has more output power. It has as much power as many portable headphone amps. But without knowing...

I'll be shipping my pair out tonight if I can make it to the PO after work.  I'll PM the recipient with tracking info.  Cool opportunity to try out a new product.  Thanks Fiio.   Review should be up either tonight or early tomorrow.
