The E5k has a very fast driver with good micro-details. I think that it's the transient response rather than any resonance. The slightly boosted high-mids would be emphasizing that as well. Another thing to note with production is that to make percussion sound more punchy, distortion is added to...

If you play some white noise through them or a song with centered highs and then swap the earbuds in your ears (Right side to left side and left to right and then back) and the sound stays centered and sounds equal then I'd say you're fine

I just did a quick check in Australia for getting the A4k/A3k (because ya'll are hyping it and I'm getting very interested in getting a pair) and a company called 'Addicted to Audio' has both models in stock (along with F-series, E-series, Heaven-series etc) so I might be grabbing a pair from...

For me the E4000 is darker than the E5000 because the E5000 has better detail retrieval which makes it seem brighter and has less high air frequencies which makes the treble presence frequencies seem louder and more pronounced. Measurement wise the E4000 is correctly brighter than the E5000 but...

The upper end pianoforte models are pretty thick in terms of "nozzle" diameter so I'm not super sure if tips would fit but I guess nobody has really tried.

What rig are you using?

Pretty sure the pianoforte series isn't supposed to have isolation or much in the way of "tips" for that matter especially the upper models

Ah, I assumed it wasn't mechanical because it was only volume that was decreased

By N3 I assume you are referring to the Cayin N3? I have the Cayin N3 and noticed that it has a less robust current output which means that headphones and IEM's that like higher current don't get as much as they could take resulting in more rolled off bass. The E5000 is a fairly bassy IEM to...

Could be several things although I believe all those things are to do with electronics. Step one for me being the most un-invasive step would be to get a multimeter and set it to resistance and then measure the resistance of one driver then then other and see if the resistance on one is...

That sets your output impedance to about 3.3 ohms though. For sensitive cans, I actually have found that -30db (roughly, cant remember exactly) is perfect. (68R series 2.2R parallel) You get better impedance matching with low impedance headphones too. A below 1 ohm output impedance is ideal but...

Feels bad bro. I'm trying to ask exactly the same question here in 2020 myself. Thanks for all the links :) I managed to get a teeny amount of information from here: https://www.head-fi.org/threads/iem-cables.432328/ The jena labs 22 awg stuff looks great if you are willing to pay the insane...

@Hooga I see you have the Heaven IV in your line up. Do you mind sharing what your experiences have been with that? A little while ago I was temped with the option of getting the Heaven IV or both the Fiio FH1 and Heaven II at the same time (which is what I opted for) but the Heaven II being...

I remember from my brief listens that I preferred the E5000 for the reasons you said being that the E4000 was a bit boomy, The E5000 had an amazing balance to that bass with its mid-high frequency clarity. I was so tempted to get it... but the price jump over the E4000's... The E5000's are even...

The FAD E2000 and E3000 are aggressively vented to the point of almost being "open" The E4000 and E5000 are much more isolating as they have a fancier internal design and much less venting. As said in the comments prior to mine, the "C" purely refers to the added remote bit. I listened to the...

I've had my Heaven II's for a while now and decided to post about them. (Got them at about 40% off) They are my first FAD IEM and they are basically exactly what I was expecting, lean, fast, bright, revealing but still sort of warm. (Prior to burn in, congested and peaky bright) The tonality...

Nitinol is a really cool material for durability reasons. It's a memory metal which means that it has a memory shape and can be deformed quite a lot. However, give it some warmth and it will spring right back into shape. It also has quite a lot of other uses and quite a high corrosion resistance...
