Yep they sound amazing. YES they are worth the money. The Bass is amazing. They are VERY exciting. I listened to them intensely for a five week period and I haven't listened to them once since then. This is because in all honesty, for me, they are a pain to put in correctly. I have tried every tip under the sun, Comply Large give me a great seal, often though I need to do so much fiddling with my left ear to retain the seal and get a balance between left and right that the left one just kind of sticks out like I am Plug from The Beano whilst the right one goes in fine every time.

They are the best IEMs I have ever heard, but for me the overhead of putting them in and fiddling clearly makes them inconvenient, hence them sitting in a drawer for a couple of months totally unused.

To be fair, it is a total gamble whether you will get a good fit, and what is worse is that if you do get a great seal it is hard to know whether that seal is blocking some of the sound too.

I have gold silver cables, again and again, they sound ridiculously amazing, not like an IEM at all, and certainly miles better than the Ultrasone IQ9 Hybrids, totally different story.

Shame that I am a mutant and have weird ear canals, but don't let that put you off.

I listen to loads of Electronica and these are perfectly suited to it, to my ears. The bass is delicious and juicily swells perfectly. Detail is good, sound stage is really something else.

I wish I could have it all but I can't.

For now it is back to closed back cans so if someone wants to talk to me, be it on the street, at the checkout till or at work I can simply lift a cup and put it on my skull, instead of getting massively irritated by having to take one out tell the lady that; no I do not want a "Bag for life" and then annoy everyone else in the queue and I stand there reinserting so I can continue to listen to their awesomeness.

Make no mistake about it, they are awesome.

Tralucent and its creator Gavin are amazing at customer service and support, really brilliant, such lovely people.

Their product is simply amazing.

I just want my cake and eat it. Then, they can bake me another one.

THIS IS MY FIRST EVER HEADPHONE REVIEW. EDITED SLIGHTLY, PLEASE SEE FURTHER COMMENTS -->
 
I recently bought a pair of these, and this is the story as far as I am concerned. Experience base goes from Etymotic's, through the Shure 535's and IE8's (Although I suspect my IE8's are knock off).
 
I went to a high end store where they would let me listen as they had spare tips etc etc, and paid £595. They are the IQ9 model. I saw them and thought that an Ultrasone IEM might be interesting so I had a predisposition to wanting to like them. I listened to some Ultrasone over ears in the same store a few weeks before, and wasn't impressed by the sound, but was by the build quality, I can't remember what they were, magnetic planar things that came in special editions with fancy titanium swirls and stuff, came in a wooden box about as big as a tea chest. So even though I had a poor experience with the brand, for some reason, and reading some reviews on here an IEM offering from them peaked my interest.
 
I brought my C4 to the shop with me so I could hear them through what would be my main source. I plugged them in at the shop and after about 30 seconds took them out and told they guy that there was no bass whatsoever and I really wasn't interested, as much as I wanted to like them, my ears told me no. I have pretty big ear canals it seems. He suggested that the lack of Bass was that I didn't have a perfect seal and scurried off to find some fatter tips which he did. As soon as I got the correct seal I handed him my plastic. There was a lot of Bass there, but totally non existent without the seal, and I have noticed that even the slightest hint of a gap and the amazing bass vanishes.
 
Then I got them home and spent some more time with them. I considered taking them back but circumstance would dictate that I had to travel so I just took them with me and hoped that playing around with different tips and positions to get a seal would improve what was a bit of an unsettled sound really. It was almost as if they simply couldn't process quickly enough, they seemed not to be keeping up with the music although there was suggestion that these things could be something special at times. It was quite confusing, but I persevered.
 
Then they just got better and better and better and better. At first the bass was just plain lazy and sloppy, but certain tracks would sound good, they were really inconsistent for at least 100 hours I would say. The details were there but not separating enough, the sound stage was there, and sometimes it was massive for IEM's and sometimes it tightened up so much that it made me think that these were a waste of time and a waste of money.
 
Now they seem to have settled into what I consider to be the best IEM that I have ever heard, I haven't heard that many though so please bear that in mind.
 
I find the detail to be amazing, and the sound stage even better, this was really brought home more when I used them with my Mac Air only for watching a TV Series (House of Cards)...all of a sudden, as it was not swamped by music, the sound stage became clearly apparent with sounds coming from where they were laid down in the track, really impressive stuff straight out of a Mac.
 
They do have an amazing sound stage for music also in my opinion, although it did take some time for this to fully settle. Now the instrument separation and the details are simply incredible to my ears, and the bass is lovely.
 
I would describe them as Ultra refined. Amazing to hear how they completely change when I change the EQ on my Colorfly, really responding to the different demands.
 
I don't get a massive feeling of a warm sound, they seem more technical than that, they seem to achieve many things, but tiring they are not, there is still a certain amount of reservation if you like, they don't punch any one frequency above others in my opinion, they are so very very balanced.
 
Incredible to listen to stringed instruments, and as mentioned they almost take away from the visuals when using them for audio from a video, they are that impressive. To be honest I kind of have an admission and a comparison. This is my second go round with House of Cards, first time I watched it on my top shelf surround sound kit at home, to be totally honest the sound coming straight out of my mac into these was much more detailed, you could really hear the separation more, exactly what the recording engineer was up to, it was interesting and ridiculously detailed.
 
Maybe people will say that of course this is the case with all IEM's, I don't know, but they are very different to my Shure 535's, another league I would say.
 
Kind of glad I had to travel now and didn't take them back.
 
Maybe it just my Dumbo ears, but the fit really really works for me. 
 
They are beautifully built, there is no questioning that, the build quality is the best I have seen or felt for IEM's, like little tanks.
 
I find the cable and the way they have coated the bit to bend around your ear to be ultra comfortable, after a while it just sits in the perfect shape, they hook on and press in very quickly and with minimum fuss.
 
I am not very experienced with IEMS's, but I really really like these and genuinely think that they are worth the money. In my opinion the sound quality is beautiful, I have them in right now, and they still blow me away. Very happy with them, although the relationship got off to a rocky start. 

First of all I just want to put a caveat on the User Interface notion. At the end of the day, we are striving for sound and we all do crazy things to get the best, gripes about it are meaningless and in reality just spoils any review and we have all been spoiled by the iPod's UI, but an iPod sounds like a lump of clay, so with that done.
 
This is mind blowing, I have no idea why this product is not more widely known about and that sales are not massive.
 
It could very well be the final word, and it has been kicking around for a while, it needs some more attention as I recently discovered. Like an ancient text, its truths can not be denied.
 
I am tempted to start to describe sound quality, but I listen through many different headphones so I would only start describing what I am hearing now through a pair of Denon AH D7100's using the 6.7mm cables.
 
This isn't a headphone review.
 
Thinking about what this product is actually capable of for a minute one soon comes to the conclusion that the design and execution is just as clever as Apple have ever done. People say it Looks "Steam Punk" or some such nonsense. No, this is a player for life, that is why it has been designed like that, not for shiny aesthetics, but so that as it ages it just gets better and more personalised and so that it will last.
 
The build quality is superb. It feels gorgeous to touch, aesthetically it sits in a class of its own in any environment.
 
There has been more thought put into this device than I think colorfly is credited for to be honest.
 
It will fit in your pocket in its case, it will fill it but it will fit there, as another review I have read alluded to, forget it if you are wearing skinny jeans.
 
What does it output?
 
Close to perfection. I can't see it being beaten at this size, ever. Something else that was very revealing was running it through my NAIM Headline. I am almost hesitant to say this, but with cans that need driving, I am not sure whether I could tell the difference between it going through my Headline and direct from the Colorfly. That is saying something.
 
Whatever phones you go for or prefer, make sure they are comfortable, as I promise you one thing, you will once again listen to your entire music collection again, repeatedly, you will wake up in the morning and get out of bed and think about putting it on, you will walk round anywhere you want as if you are in a reference studio with the world playing a film going by. You will stop being able to hear people and you will not do much talking either.
 
I do not think that it is overpriced at all, it is ten times the quality of an iPod and not ten times the price.
 
And it has a soul.
 
The EQ settings do work very well indeed, again more thought by clever people.
 
For the peripatetic audiophile, there is no other unit.
 
One very very happy customer, it isn't often you get more than you hoped for these days. Colorfly give you it.
 
Happy to answer any questions, I have haunted this place for years and years, I have never signed up, just taken, not contributed. I simply had no choice but to speak up about this amazing piece of kit.
