Rare - black aluminum LCD-2 was only sold for around a month at the end of 2016. Mint condition except the one time my daughter scratched where the earpads attach, which is easily replaced. See photos. As a result, have kept it in the box and used only a handful of times. Excellent sound...

Does the LCD-2C also have that dip around 4 KHz?

Looks like some with the Jotunheim may have a similar hum issue https://www.head-fi.org/threads/schiit-jotunheim-review-preview-head-fi-tv.818323/page-388#post-14362130 https://www.reddit.com/r/headphones/comments/8z8k27 I am out of town for a while so I can't test, but can those with the...

Of course there's noise on the power line, as there always is. It's up to the device to have enough filtering to deal with it - other amps on the same power outlet have a nice black background. My question is along the lines of, is my amp within spec or is the noise in my home greater than...

Looks like we just need to find one that outputs 14 VAC and at least 1.5 amps. But yeah DC switching ones are much more common So it's even audible the Q701 and DT880 on high gain (not normally needed unless listening to high dynamic range classical music or using heavy EQ). I did find my...

My point was to find out the cause of the discrepancy not better sound. The ones you are using are not stock, correct? Insertion depth also matters. All of these things drastically affect IEM sound Of course we could chalk it up to different ears or QA

You mentioned earlier wide bore tips and removing the filter being important, perhaps try using some narrow bore tips and putting the filters back and see if you can reproduce their experience? And maybe a phase check...

I'll give you the benefit of the doubt and assume you couldn't access the drop page. They give you the option between a 3 pack of one size or one of each size.

Does anyone get a low frequency hum? It does waver in amplitude and harmonics over time, but mostly remains lower frequency. My Ety ER4P picks it up. EDIT: also hear it on all of my headphones (even the 2016 LCD2F and DT880 on high gain) It's not the typical noise floor that sounds like white...

2 and 4 are mostly from loudspeakers equalized to flat in a free-field, probably the effects of ear/pinna resonances. 1 is a listener preference on headphones. Here's a plot of the original harman curve vs flat loudspeakers. 3 is new from their in-ears test and it's not clear if it's from...

Yeah I've been trying to figure out which ones have bass vents and on which side. The ES4 has 2 of them facing the ear, but maybe since there aren't any facing outside it still does well? I also read that the ZS5 isn't great, but that appears to only have 1 vent hole facing the ear, though it...

Thanks for the isolation comments! How much worse is the ZST/ES4 than the ZSR/ED16? Have you compared other brands IEMs isolation? Or the KZ EDR2 style?
