Thanks for the review. Logitech are a strange company sometimes ( why get rid of squeezebox!) but the ultimate ears division are capable of good headphones. The triple fi 10s are the best iem's ive heard so far.
Hey Dale, great review and wow another suberb sounding headphone! Just to clarify: Are you saying that it produced audio distortion with the active NC off? That's the opposite to what I'd have expected. And I can't help but mention the classic - the Bose QC15? Could you say how it compares to that in terms of audio quality and active NC isolation? - which would be bet for super noisy environments?
Oh and could you how some settings for the EQ? I'm not familiar with the Apple options but what about Foobar?

My 6000 was defective, as was 2(!) of Tyll's 4000 samples. Not good. Anyway, got the new one which works. The passive mode has a very recessed treble, and the active mode has a very boosted bass. I haven't tried a critical review of passive mode and whether a treble boost there would sound as good as the bass reduction in active mode. Instinct says it would be best to have NR off, but that probably won't apply with the 6000. The NC seems to do exactly like my Bose QC2 - sitting at the end of a pier with ships in the harbor and all kinds of noise, in passive mode the headphone blocks highs like an average sealed headphone (or slightly better), and when NC is switched on, the lower frequency sounds just disappear (amazing) but people walking by I can hear just a small bit of their voices, just like the QC2 when riding the big passenger jets.
Edit: I'll look up Foobar settings when I get back.
The Foobar2000 setting I use for "same as iPod" Bass Reducer:
-1 db at 440 hz with one db decrements, to -6 db at 77 hz and 55 hz.
The Foobar2000 setting I use for "same as iPod" Treble Booster:
+1 db at 1.2 khz with one db increments, to +8 db at 14 khz, then +7 db at 20 khz.
This is based on the default Foobar2000 equalizer. I also have a 30+ band equalizer but rarely use it.
I swapped my UE-6000 today and now passive mode works. But passive mode sounds like a blanket is over the sound, similar to many headphones these days, and even treble booster is not enough to bring it up within a mile of the Shure 1840, which isn't a "bright" headphone. So a certain reviewer who likes this muffled sound (and it's muffled) must really dislike the treble end of the spectrum.
Thanks Dale! Wicked info there!! Thanks very much
The 6000 treble in passive mode is so recessed it sounds dull even with ipod-equivalent treble boost. Now with 3 defective Logitechs out of 5, I hope I don't have to contend with large sample-to-sample variances.
Here's the Youtube video, with some info that's not in the text review. http://youtu.be/c39JATw5HU8
I updated the hifiheadphones review, so for those who've already read it here's the update:
(1) Comparing to the v-moda M80 headphone, which is fairly neutral with a soft (slightly recessed) treble, the UE-6000 in Passive mode sounds like a blanket has been placed over the drivers - very muffled and very boomy.
Tonight I checked the Apple store demo of the UE-6000 in Passive mode, and it sounded very good, like a totally different headphone from mine. So between Innerfidelity and I, that makes 4 defectives out of the first 6 UE headphones.
Oh wow, this is insane!! So they made a great headphone and then totally ruined it, giving the consumer zero confidence to buy one. What a waste. I makes me wonder if it sounding good was just a random mistake
I enquired of Logitech also about replacement cables, given many reports of cable difficulties not to mention the near impossibility of getting the cables securely into the UE-6000's I had. They replied back, that no replacement parts of any kind are available. They do have a great sound, but one wonders about how it could be so dissociated from these other things.
You should update your review with this info. I must say this increases my curiosity to review them but not so much to buy them. If I was looking to buy them this information would put me right off! I guess you didn't get yours through Robin, I wonder if he will get them in.
As a buyer, wanting to get the best for my money and not owning lots of headphones I would be nervous as hell that when I bought them, if I didn't like something, I would be constantly wondering: Is that sound aspect something that just doesn't suit what I like, or is it a defective unit. It would constantly drive me crazy, even if they were actually as good as they could be.
I think the review has been updated in all postings and youtube. If I were a dealer, I would not sell any factory sealed boxes. All would be opened and tested, and I would charge extra for screening them. But when they work, oh my!! They are good.
I've spent three nights now comparing the UE-6000 to the Shure 1840. Basically the 6000 sounds like an 1840 with bass. It gets better than that, though. I have a number of tracks that compare very fine detail and harmonics, and the 6000 is equaling or beating the 1840 right down the line. This is in Active mode with bass reducer, and the 1840 played flat (no EQ).
Yesterday I checked Innerfidelity's frequency response measurement of the UE6000 in Passive mode and compared it to the Sennheiser HD800. Compared to the HD800, the UE6000's treble is down** the following amounts: -6 db at 3khz, -7 db at 4 to 5 khz, -11 db at 6 to 7 khz, and -9 db at 8 khz. The HD800 has a fairly strong treble that's not excessive, so at 6 key frequencies from 3 to 8 khz, the UE6000 is down an average of 8.5 db. Is that a lot? Yes, but it might be even worse. If you have a sample that varies from spec by 3 db (which is probably generous for a product with an iffy QC record), if you add a variance of 3 db to that you're then down an average of 11.5 db, which is very bad. If you subtract a variance of 3 db from that then you're only down an average of 5.5 db, which isn't quite as bad. And that's why it's important to have a tight spec, plus not be far off from a reasonable high fidelity standard, so the variances don't kill your sound. And it probably explains most of the review differences.
**For example, if the HD800's output at 5 khz is 6 db lower than its average midrange output and the UE6000's output at 5 khz is 9 db lower than its average midrange output, then the UE6000's output at 5 khz is down 3 db relative to the HD800.
Last thought: I don't know where Innerfidelity's UE6000 sample measurement falls among the samples being sold now. If their sample had treble output greater than the average sample, then the lower-than-average samples would be down twice as much as I speculated on. For example, you'll see in the All Measurements PDF that some of the famous brands which have measurements of two or more samples sometimes vary greatly in the measured responses.
