AKG new headphone K545? - Page 86

post #1276 of 1722
I liked the Momentum on ears when. I tried them a while (in store trial) but do also prefer the K545.

I am trying a pair of the Mikros 90 right now. So far I am liking them. At their price they are very nice but I would struggle to justify their original retail price. But I will see how I like them in a week or two. Also have to find an android cable.

Here is a quick A/B I did this morning between the Mikros 90 and the K545.

 

OK, A/Bing the M90 against the K545 this morning after a night of burnin. I have a small volume controllable splitter so I could volume match between the 2 headphone (done by ear so probably not perfectly volume matched but close). In this test I am using my desktop computer paired with my Little Dot DAC1 and a Bravo Ocean amp with stock tube.

Here is one of the tracks I am using for testing. This one has some seriously nice sub bass.

I then used this Patricia Barber - What a Shame song as a second track for overall listening.

 

The end result was the K545 winning the sub-bass end still but even with only one night of burn-in the M90 was getting close and good enough I could be pretty satisfied. The M90 has more warmth than the K545 though but only slightly, to me it has a very similar midrange to the HP50. The added midrange did bring out the sibilance inherent in Patricia Barber's recording though whereas the K545 was slightly more relaxed and enjoyable in that regard. I think the M90 managed the drum kit a little more cleanly though and does snares and cymbals a bit better. The K545 has a more spacious sound stage though.

I would say the K545 offers a slightly deeper bottom end and a slightly V shaped signature in comparison to the M90 but we are talking only shades difference between. Between the added comfort of the over ear design and less clamping of the K545 combined with a slightly more relaxed sound the K545 is the ultimate CHILL headphone for relaxing and just floating away in your music. The M90 on the other hand with it's stronger clamp and slightly more aggressive and detail oriented sound is an excellent serious listen headphone and better portable option due to it's higher isolation. They make one hell of a one two punch for me.

Damn, the M90 is a really good looking set of cans

Is the Mikros 90 is an on ear headphone?

How does the soundstage compare with the K545?

I'm definitely considering buying these before the price goes back up. :gs1000smile:

They are on ear and are not quite as big a sound stage as the K545. I will be rewriting my comments above as I found out my splitter was affecting the sound. So stay tuned.

The only thing about the Mikros is they do have a lot of clamp so you have to play with the fit to get them comfortable. It's weird but they don't bother me as much as a lot of on ear headphones.

If I can get it at a third of the MSRP, I could easily deal with the clamp. I can hardly get over how stylish those are. lol :tongue_smile:

 

 

Just a random question: has anyone ever tried the HM3 pads with the K545? It seems like they may fit.

I'm asking because it doesn't seem like MP4Nation is restocking the HM5 pads anytime soon. -_-

I retested the songs without the splitter and came to the same conclusions I listed above. Bang for the buck the Mikros 90 is an amazing headphone right now no matter the clamp. I will likely just stretch mine on something slightly larger than my melon while I burn them in to help with the comfort a bit. They also come with one heck of a nice case BTW. Before I forget though, they only come with an apple cable. In my case I use an android phone so switched to my Vmoda M80 cable and holy moly did it ever open up the sound! So playing with 3rd party cables is a definite option with these.

Thanks for the info. These cans are definitely going to be my next buy.

 

And a question about burn in: I haven't burned in my K545 since i got my new pair about a week and a half ago. Would it be redundant to burn them in now? Or will it improve the sound still if I burn them in this late?

 

Is there a cable that one could use with the K545 that would improve its sound?

post #1284 of 1722
I really just used my K545 because I liked them out of the box, if I burned them it was just with music for a night or 2. I also have only used their stock cable. Sorry I am not helping much on the modding front.

Burn in will happen as you use the headphones...  It's an ongoing process, but if you've used them for 30-50 hours already, then you're good to go.  Heck, most change I hear only occurs during the first 50 hours XD  There are exceptions though (Dunu Hephaes sent me on a roller coaster during burn in XD).  As for a cable that'll improve sound, an impedance chart would be better suited for that XD

The right driver experiences significant flex which basically does this: As pressure increases or decreases (pressing or releasing, or just placing them on your head which creates some pressure) the sound from the right driver decreases dramatically, down to maybe <50% volume, until a "pop" sound is heard and the volume returns to normal.

In practice the right driver is always a bit quieter than the left (tested this with some blind left/right swaps with a bit of help, that driver's always easily identified as quieter). Depending on exactly how they end up sitting on my head it can be a lot quieter and the cup would need to be pushed on to "pop" the driver (which doesn't sound like a good thing at all when it happens).

I really liked the sound, enough to overlook the kind of tricky seal, but there's no way I can put up with this messed up driver. Considering the fact that I'm seeing others reporting the same issue I'll likely return instead of trying a replacement. The other driver has a small amount of flex as well (but no variable volume) so I wouldn't be surprised if it's a relatively common issue.

This happened to me twice... both black versions from razordogaudio...

Best Buy has these for $200 and is more reliable than razordog. 😃

Too bad I bought then before they went on sale -_-

This seems to be a serious QC issue on hand. As I mentioned in my prior post, I had driver issues with both my K545 units I had my hands on... one being an exchange/replacement for the other.

Only the first pair, however, had the crinkling issue...

Razordog is extremely reliable. Brian replaced my first unit and refunded me for the second...

Its not razordog... its AKG...

And doesn't Best Buy do a 30 day price match? Go get your partial refund, if so, my friend...

I said that because someone else had problems with razordog earlier. Ignorance got the best of me lol.

And sadly it went on sale more than a month after I bought them.
