Doesn't look like there's a thread for this yet so I figured I would start one as I just received mine. I took some pictures for everyone. The quality isn't very good since I don't have a digital camera so my apologies!

Initial impressions on sound - sounds very intimate, powerful but accurate bass. Good separation between instruments. From memory, definitely less thick than the IE8 but probably a good middle ground between the IE8 and something less bassy. Only listened to one long song on it so far. Dream Theater - In The Presence of My Enemies (pt 2) on my Cowon D2 - 320 kbps lame mp3.

Feel free to ask questions and I will get to them when I can. I will write a more detailed writeup later and offer a comparison between this and my PFE because my IE8 is out on repair.

Quick tidbit about the sensitivity. I know some people were worried about how hard they are to drive considering their abnormally high impedance for IEMS but do not fear. Running them from my D2 so far - 18 volume is pretty comfortable for me and that's actually just around the same range I listen to on my IE8's depending on the song. The IE8 is only 16 ohms.

Thanks. Good to start a new thread. Many of us (me!) can't wait to see/read the comparisons to SE530, W3 and TF10Pro.

 

[Zalithian]

From memory to compare to the IE8 - The UM3X offer superior clarity in all aspects and sound very balanced with forward mids. There isn't much treble sparkle but it's very detailed imo.

Overall so far, I would say the UM3X sounds less fun than the IE8 but is more definitely more accurate. That doesn't mean the UM3X isn't a fun IEM. It's more fun than the PFE's based off memory from listening earlier but I will do an A/B soon between the two.

 

[dunnowho]

does the specs on the box say 27 ohms or 56 ohms? coz mine says 27 ohms...

 

[toughnut]

Ah, great way to start month of May with another new FOTM

 

[Zalithian]

Hmm.. impedance on the box does say 27 Ohms which is far different than the 56 listed on multiple websites, including Westone's.



edit:
Powderhound just confirmed it was a misprint in the other thread and it really 56 ohms. It is surprisingly easy to power for 56 ohms, though.

 

[dunnowho]

haha. another discussion on different tips once again?

edit: ah, dang, it would've been better with higher impedance, now it will probably hiss with t4.

 

[toughnut]

It's 56 Ohms. powderhound mentioned it before.

 

[theory_87]

Although it 56ohm, it hiss a little more than my the rest of my IEM

I've taken the liberty to include these fresh new posts below here as I think they're now more relevant here. They're taken from the other UM3X thread: http://www.head-fi.org/forums/f103/w...ounced-418650/ ).

Wide open and inviting. Added the much need sparkle that se530 lack. but not to the extend of tf10p. I just thought i end my portable journey with T1 but um3x force me to open my wallet once more.

Mid wise, both are different. same similar level of details but um3x sound clearer. highs, t1 sound a tat louder but um3x sound more extended. Basically, the main different is in the mid. Than either you go um56 or ES3x, else stay with ck100. All my finding is base on um3x with um56 hence I do not know how universal ear sleeves will fare

UM3X Specifications

Sensitivity: 124dB/mW

Frequency response: 20 Hz -18 kHz

Impedance: 56 ohms

Driver: Three balanced armature drivers with a passive three-way crossover.

We do apologize for the misprint and confusion.

That's the same spec as the ES3X, if I am not mistaken? Time to save some money for a pair of this

No problem. I;m interested to hear from ES3x owner who um3x sound.

 

[sennmann]

how is the um3x in comparsion to the w3? are the mids more pronounced? is there a little bit less bass? the w3 offers a lot of it? and how are the highs exactly as good as in the w3?

 

[robm321]

Sounds very similar to the impressions of the ES3X - that's a good sign considering they have the same drivers.... very encouraging impressions - I'd imagine they scale well with an amp too.
