Guys, I finally got my K5. Magaosi must be listening, because the cable I received looks nothing like the brownish one seen in this thread. The one that came with mine is a really nice multi-braided cable, with half copper and half silver-plated copper wires. It has really comfortable memory wire ends (it's one of the "wireless" types, where there is a molded shrinkwrap acting as the memory instead of a piece of embedded wire). I wish more manufacturers would use this style of memory wire (a few do, but not nearly enough IMO). Zero issues with loose or faulty MMCX connections, and the sound is great with the included cable. I'll swap out the stock cable with a few other MMCX cables to make sure there's no sound improvement to be had. But the included cable definitely has a thumbs up from me so far. I posted detailed cable photos 2 posts below. I got the package with no extra bluetooth cable - just the wired cable. I omitted the bluetooth cable to keep the overall cost down, but after reading positive comments about the bluetooth cable I kinda wish now that I had got it (if for no other reason than to use it with other IEMs). With the right tips and a good seal, it is definitely a step up from the K3 Pro. The fit and comfort is excellent. The IEM is beautiful to look at - the acrylic is crystal clear, giving a clear view to all of the internals (drivers, tubes, crossover, etc). Very mesmerizing to look at. I got the blue and red color so I could easily distinguish which side is which (the color is only a thin layer on 1 side - 95% of the IEM is crystal clear). I would have been just as happy with the totally clear or black colors as well. Oddly, it doesn't respond well to EQ at all - even if I make minor changes in Rockbox, it distorts really bad (which I've never experienced with any IEM). I don't really need to EQ the K5 though - I like the sound as-is, but I was just playing around with the EQ to see how it responded. So the distortion when EQing is no big deal. I also don't have any of the hiss some have mentioned - mine are as quiet as a mouse (at least on the sources I have tried so far). I'm planning on doing a review of them, but from what I can tell so far I really like them. As we all know though, this is a very competitive price bracket (with tough competition). I don't personally have any $150-$200 IEMs to compare the K5 to (such as the B400), so I can't comment firsthand as to how the K5 stacks up to other competitors in the price range. But so far I'm totally happy with the cost to performance ratio, and I'm glad I tried it.
