KEF M500/M200 Impressions Thread - Page 54

post #796 of 1186

Does anyone think that running the M200's off an iPhone 4 would be a good idea? Thinking of picking these up, but havent got money for an amp.

Can't help you there (don't have an iPhone), but I see that you are into metal. You might want to check out d marc0's thread. He loves metal, and provides his opinions about the iems that he has (or has auditioned) and how they do with metal. Might be helpful!

I have an iPhone and an iPod touch, and the KEF M 200 ran just fine off the iPod and iPhone. Great sound, and using my amps didn't elevate the sound much , because the M200 is already a marvelously tuned IEM. Just be careful of fit and build quality. It's not very good.

I know that there have been a few cases of one of the drivers stopping working. I would be interesting to know though how many cases of that happening percentage wise there are.

I was told from a KEF insider that there was a large batch of M200 that shipped with faulty LF drivers. I got one of those. My replacements didn't seem to have that issue, but I sold them anyways because I wasn't willing to take the chance. I've got equally good IEMs already that have superior fit and build quality.

Hopefully the problem is no more outside of that one batch.

 

All I can say is that mine have continued to work flawlessly, and I'm very happy for that because they are one of my favourite iems.

Mine is from first batch and have been fine this whole time. M200's take amping very well also.

@DannyBai and @WaynesWorld i agree with both of you. When mine were working, they had sublime sound, and I personally was one of the folks who didn't have fit issues, so I loved that warm lush sound of the M200, it's my preferred sound sig. I just didn't trust the BQ. Aside from that, the M200 is all class.

Does anyone know have measurements of how M500 reacts to high impedance output? I'm using them on AK100, and it feels a little different from when driving them from UHA-6S.MKII. IDK how exactly, and M500 isn't clear enough for me to distinguish what exactly is happening.

Worse damping factor which in theory, contributes to worse decay and differences in volume in the frequency response curve.

Well, that's true, but damping varies from headphone to headphone. Sometimes, damping certain frequencies actually flatten the sound(like W4 and UE900 benefits from high oi). That's why I asked if anyone knew how it affected the M500.

 

But yeah. I'm not certain myself how the sound changed. I guess change is subtle.

Just discovered something quite nifty about the M500. I found the frequency response to have the bass of the TH900, the mids of the HD800, and the highs of the LCD-XC up to 10kHz where then the M500 kinda rolls off in the high treble. Not sure about the reputation of the treble of the LCD-XC, but the TH900 are known for its bass, and the HD800 known for its mids, so that places the M500 is pretty good company. :o

I am looking forward buying M200. I currently own a pair of phonak's audeo pfe 122 with fiio X3 as a source and i would like to know if someone has heard them both and if M200 are an upgrade over pfe 122. 

post #809 of 1186

I have both. I like the kef m200 much more.

Better detail, soundstage and bass.

You do understand that just because a frequency response graph between two headphones may be similar in some ways, they don't have to sound similar at all because of it? There are many other factors involved..
