Thanks for posting this!

Does anyone have a summary of known working mods for the mk3's? I know the info is probably in this thread somewhere but 141 pages are a bit much to read through.

I would contact FiiO directly if I were in your position. You can PM them here> http://www.head-fi.org/t/757129/dont-be-shy-contact-us-directly-with-problems-with-your-fiio

You would think so but since several people are mentioning that they have a problem with it and are damaging their players it is apparently not springy enough!

The spacer was off. If the plug on the K5 were in the position towards the front of the amp (in that little space you see there) it would work fine for the X3ii. I wonder if you are supposed to move it somehow...like maybe removing those 2 screws and then changing the position??? I don't have...

With the X3ii the chance of "trying to plug it in at an angle" is 100%. Look at the photos in your previous post. The port on the X7 is centered and the port on the X3ii is further toward the front of the player. This is why you see users posting that they had to angle the X3ii toward the front...

I tried that and did get it to go on the plug but it still didn't function properly. No amount of wiggling made any difference. It was at that point I decided to return the K5 for a refund. I'm going to keep watching this thread to see what experience others are having. I may try buying another...

That's good to know. Did you have any trouble at all getting the X3ii to seat in the dock?

Two words..hydrogen peroxide. Tilt your head to one side and place a few drops of hydrogen peroxide in your ear. Wait 10 to 15 seconds while the wax dissolves. (you will hear a crackling noise as the peroxide bubbles.) Tilt head the other direction and let the peroxide and dissolved wax run...

I really hope this docking problem, which seems to be limited to the X3ii, gets resolved somehow. The features, styling and specs are outstanding at this price point and I would love to be able to purchase this amp again in the future. I wouldn't even mind if it didn't have the dock, but if it's...

Very interesting thread. I've owned several different "mid fi" headphones and have never really heard anything "out in front of me". The sounds I assume should be in front of me are "in my head" even while the left, right soundstage seems very natural. Oddly enough, my newest cans (ATH900X)...

This is the same issue I had with my K5 - X3ii combo. I could not get the X3ii to make a good connection via the K5 dock yet it worked perfectly connected directly to my PC....which means the problem is in the K5 dock. Just as what has been suggested to you, some here seem to think I didn't put...

The one and only USB cable that comes with the K5

Yep, I'm aware of all of that. My X3ii has been working fine without the K5 in the mix. The X3ii has the latest firmware (V1.4) and I have the latest TUSBAudio asio driver installed on my PC. What I am trying to tell you is the X3ii will not dock with the K5 correctly. It won't plug in, it won't...

No, I tried that too but it didn't work at all/ At any rate I'm not going to go through all that trouble every time I want to dock my player. I suspect that the dock plug on the K5 I received was defective in some way. It really should plug right on there without any effort.   Just FYI, the K5...
