Can YOU tell the twins apart?

[Rinoa Caraway-Heartilly]

Yeah. Telling them apart by their hair is easy but it's hard to constentaly watch their hair. Their voices is how I tell them apart. After watching it so much I don't need to see who's doing what. I just know which one is which.

Kaoru♥  

[klowag]

Kaoru's voice is higher and the only reason I know if it's him is because I part my hair the same way as his. In the manga, it is a bit more difficult to tell them apart since their hair style changes often and it may look like there's no parting in their hair at all. But I usually just wait for someone to say something and then i'll know who is who.

I can tell by their mannerisms, actually. When Kaoru speaks or acts, there is a a slight hint of mercy and maturity. Hikaru is more wild and a little more open to how he thinks.  

[Kadoon]

Like almost everyone else; yes I can.
How? Again its all been covered.
They part their hair different, usually Kaoru's hair is parted to the left where as Hikaru is parted to the right.

Their voice tone is different, Kaoru's is quieter and more mellow, yet Hikarus is deeper.

Voice is probably the easiest way when it comes to the anime, but for the manga it would be actions and personality.
They are called the naughty type, but, Hikaru would fall as 'naughtier' then Kaoru.

Everything has been mentioned, I like everyone's views and descriptions

Hikaru has a more sullen attitude about him,while Kaoru acts more....'foxy',and has a smooth tone.  

[Naru_San__Hinata]

in the anime i can tell them apart by there voices and the way the hair is parted. in the manga i tell by the hair. i like guessing who is who when they play "the which one is Hikaru game" heart  

[redheadsrule13]

yeah i can. i usually tell by their perosnalities most the time. Like Kaoru seems nicer and a bit more shy. Unlike his Twin Hikaoru is more wild, and willing to take risks.

i can on there persnalties but i still trying to see wich twin has wich persinality for example only one likes harhi and another wants him to be social and cares for him on that reson i noticed this when harhi when out with one of the twin

Why is a raven like a writing desk?...

It seems like all the ways I can tell are covered! >w<
I have not read the manga yet, but from the anime, I agree with the difference in the attitudes. Although sometimes it is hard.
Most of the time, it's just the voice which helps me. I don't pay too much attention to the parting in the hair. :3

...I haven't have the slightest idea...

 

[LazyButler]

Well, there persanalities are pretty different, Kaoru seems more calm while Hikaru is more tempermental. And I find myself constantly watching their hair too xD

It was harder in the beginning than it is now 3nodding  

[mitus]

i can tell them apart even if their hair is messed up but they have to say something and i don't mean voice tone either i mean even in the manga i can distinguish that it's kaoru and hikaru by what they say but to be fairly honest there is occasions that I've got them mixed up but normally i knows who who's  

[TwincestCX]

Of course I'm a twins fanatic and i cosplay them almost daily. First Hikaru dose seem more mischiouvs and no matter what he is ALWAYS seme in there little moments. His vioce is abit lower then kaoru's also. Then for kaoru his vioce is more higher and sounds raspyer then hika's, he also is uke and seems to care more for his brother.  

[Hello_Kit_Kat_158]

I can tell them apart since Kaoru is always on the person left, and Hikaru is always on the preson right if you look at them in the face.
