IMHO the treble is very gently rolled off above maybe ~10k. But its gradual enough for me not to consider it a flaw, and more like a sonic character. The treble is there IMHO, its just so smooth and pleasant. Its not the kind of treble thats going to jump out at you. Its a lot like how Grados present upper treble. IMHO the x3 leans more to the warm side overall, compared to cans like the PK1, Jays or ety IEMs.

I haven't heard the futuresonic M5... yet

Yes That is my opinion even after 35 hours of burning. Having upper trebles doesn't have to be harsh and on the face type thing. DT990 does very good upper extention, without being harsh and ear piercing. So does HD650! CX300 has some unrefined highs. KSC75/35 has beautiful trebles for its price point.
X3's frequency response is said to be 20Hz-22000KHz. I expected a better upper extension from it according to specs. But this is not to say X3 lacking in trebles. It has smooth controlled highs but lack upper highs a tad more than desirable for my taste.

The X3's have a impedance of 12 ohms btw.

Kaushama,

How would you compare X3 to your M5 and KSC75 ? (I really appreciate soundstage and clarity of the KSC75 at least compared to my Sparkplug !!!!).
I need a new IEM and I hesitate between X3 and M5. Which one would you recommend ?

This will answer part of your question: http://www.head-fi.org/forums/showthread.php?t=243575

It's a hard one to search for because 'X3' and 'M5' are both too short to search for on the forum.

Nice review ands welcome to the Crossroads club! To think that my first review was too enthousiastic and got deleted

Thanks for the link Bebanovich (nice avatar picture !!!)

Now one remaining question to kaushama : how does X3 and M5 compare to KSC75 (my only headphone reference). I anticipate a decrease in soundstage but I don't want to be disapointed on other criteria !!!!

If soundstage is what you are looking for, you should get open 'phone instead (but not Grado). Being as close 'phone in natural while placed so close to you ear, canalphone's soundstage is minimum at best...

if xb is aluminum it will make me feel a lot better about the buy. although i want good detail/resolution comparable to my e4c. also would the isolation be better?

 

[aaron-xp]

Nah. "Traditional" IEMs have a better seal that the XB/X3 as they are able to go deeper into the ear canal, although that is not to say that the XB/X3 have horrible noise isolation (I feel that it is better than that of the EP630).

oh i know that, i meant XB > X3 in terms of isolation because of aluminum

Correct me if I am wrong, but just on sound conduction along, didn't metal conduct more sound than plastic since it is more dense?

Yes, that's right.

What were your findings? I am experiencing the same thing. I can't quite pinpoint a freq range as it seems to be very broad.

 

[Bisco82]

the x3 just does not have an in-your-face sound to them. Rather than breaking them in, just listen to them and let your ears get used to it
