Yes. Depending on the Amp. I would pick a cheap cMoy and put a LME49720 NA in it, pairs very well.

 Thank you for the quick reply. I just ordered FiiO E6 though, don't know your take on that?
I probably am gonna buy some better and more expensive headphones at a later point, and then I will probably invest more money towards a FiiO E07K.

Invest in the JDS Labs C5. Fiio are fine for cheap mass produced products. But JDS Labs are a big jump in quality vs the Fiio.

Today I got a 2nd hand K518 DJ and LE.

 

I opened them up to replace the broken cables and give them a good cleaning, and I noticed that even though the drivers were mostly the same design or formula,

they were actually different - the magnet housings (center-middle) of the driver were noticeably different.

 

After putting them back together, I noticed that the DJ had more treble.

After pulling out the foam on the LE, they now sound fairly similar... the DJ still perhaps has more treble.

 

Also I notice that the foam gives the sense of a larger soundstage, so right now I'm liking the DJ + foam sound quite a lot over the other, which just lacks 'bite'.

 

I should probably add pics of the drivers. 

Fun fact - the drivers look practically identical to some I pulled out of a Creative Tactic3D Alpha headset. 

I will probably put those along side for comparison (just for fun).

If I feel really creative this week, I might even do a full transplant and see if they even sound the same/better/worse.

That explains why there seemed to be perceived differences between them. smily_headphones1.gif

For a simple mod, try the blue tack with the K518. Definitely does help with improving the bass SQ and the way the rest of the frequency response is emphasized.

Blu-tack mod sounds really interesting. I hope it doesn't make the treble sizzle... it's already on the edge of my fatigue threshold.

post #112 of 119
Sorry. I can't tell you that. It's been so long since I did the mod. But it seemed to me an overall good improvement. And reversible if you don't like it. smily_headphones1.gif

mmmmm.... blue-tack mod minus the foam produces a much tighter bass and cleaner FR.

This thing is now punching way above it's RRP. 

 

I thought it would be subtle, but it's quite a clear margin between the two now.

Especially midrange now sounds close to what I would call neutral, or at least natural.

The bass was that kind of mushy/boomy and bleeding into the mids originally, if I remember right. All of a sudden, it tightens up and gets nice and punchy. I wouldn't say it's very textured to me, but it is way cleaner that I remembered it being originally.

Now if AKG had just tuned it like this and put a little bit plusher pad to improve the comfort, I bet they'd be selling the heck out of them. smily_headphones1.gif

From other's comments I've read, it looks like they're doing the opposite: making them cheaper and increasing variation in quality. 
Unless it's just the Chinese manufacturer using the same 'driver type' from various batches... which I would guess doesn't even reach AKG's radar in Austria or USA or whatever.

The only difference I can see between the Creative drivers and the K518DJ is the colour of the copper voice wire:

- Creative = orange voice 

- K518DJ = red voice

Also the 3 ports on the AKG have been glued up totally.

The 3 ports on the Creative have only been covered by a semi-permeable fabric (probably to tune them bassier) 

 

The K518LE has an identical diaphragm, plastic housing, vents to both.

It has the same orange voice as the Creative driver.

BUT the magnet housing is the big difference. If they house fractionally different magnets this may explain why the LE wasn't as treble-happy as the DJ.


Clearly all three are from the same manufacturer.

 

I won't do a Creative driver transplant as the AKG drivers are glued in place with a solid type glue.

The Creative drivers were only held in by a rubbery type glue.

Could very well be that they are both sourced from the same Chinese factory. Note that Innerfidelity measured slightly different impedance between the DJ and LE:

(see the rating in the final numbers, bottom right).

I don't know if that's just production run differences or slightly different drivers.
post #118 of 119

Well even in higher end stuff, drivers will measure slightly off the spec-sheet, but they'll just be matched closer as a pair.

Wouldn't surprise me at all if it was just production variation.

Are they still worth the money?

 

My only headphone is the Superlux HD681 Evo, and they`re on sale in one store in Brazil right now.
