The mystery of EA1000 nozzles

These are measurements from exactly the same volume output from the amplifier. As you can see, bass is exactly the same, and the red nozzle is the mildest one.

Here is the tricky part: the red nozzle is the one WITHOUT any foam or dampening material inside. You can see the difference reflected in the dB value heard by the microphone: red nozzle (least dampened) is the loudest, black nozzle (most dampended) in the most quiet. Yet, the red nozzle has the least upper midrange. Why dampening shifts the energy down to upper midrange region?

@DynamicEars any guess?

Look at this beauty

No smoothening was applied on the graph. It's the RAW response from the microphone. Look how smooth it is!

A new contender for the budget favorite three and the rediscovery - the KZ DQ6S (17 USD inc. tax)

The channels inside look solid, maybe something has changed since the legendary topology mishap. I don't know, sound is really good.

I'll be pulling the trigger on the Hydro soon to compare how CCA manage to achieve a totl presentation/tonality - by implementing better BA's than the Rhapsody...

@PhonoPhi casually brought up something in passing that had me thinking. Anyone read any research about EST electromagnetics and how that could show an increased potential for brain cancer? Several big name musicians developed brain cancer. So many people worrying about their cell phones, and those typically aren't at your ear for hours at a time, while an EST driver could and would. Just interesting, because of the energy it emits.

Regarding this issue - BT earphones are definitely a proven health hazard....I guess that EST electromagnetics must be emanating a toroidal field, which in turn, no doubt interacts with the toroidal field produced by our pineal gland?? This crucial gland is comprised of piezo electric crystals. MF Trio are my only EST set - & luckily I don't use them often enough to be concerned.

@activatorfly Hydro looks great, especially internals implementation for KZ/CCA. Tuning wise it looks also nice

Any opinions on the fiio Q5s? I can get one new for around $160

Can be that the metal mesh is different?

I like OG graph better tho

On the contrary for me personally. ...that's how we all are differently psychoacoustically imprinted .

Intrresting graphs. I would suggest to look at nornalization first. If dB values are correct (and they should be) the non-normalized graph for the red nozle should be higher in magnitude/intensity. Software then likely normalizes all graphs by default to the same intensities at 1 kHz or lower.
As for the frequency shifts - oscillator dampening decreases its frequency, and it should be applicable to the standing sound waves in the coupler (enough of the older Phonophi, right?)

I have numerous friends and family in the medical and scientific fields, and my background is in law, so I've read more precedent than I care to consider.

The frequencies emitted by these devices have no measurable effect on tissue. This isn't like putting a tiny microwave or radar station in your ear. Electrostats are not dangerous (and these are electrets, far weaker), it's very mature and well understood tech. Suggesting they are dangerous, without basis, is irresponsible. Your post amounts to scaremongering, nothing more, and I won't be addressing it further.

Scaremongering is not right.
Bringing potential concerns should be right (and potentially helpful).
Bringing concerns about concerns should be similarly instructive.
Scaremongering efforts to shut down any potential concerns are not right as well (and perhaps the most to be concerned with, given the tendencies of the current "cancel culture").

I hope we all (here and elsewhere in life) can find a good balance in polite and respectful discussions.

I'll be pulling the trigger on the Hydro soon to compare how CCA manage to achieve a totl presentation/tonality - by implementing better BA's than the Rhapsody...

Aren't the BA drivers absolutely the same in Rhapsody and Hydro?
They are the same according to KZ description, just twice more drivers in Hydro. More drivers is better in several aspects: smoother, more details potentially without "artificial treble boosting", while less directly influencing tonality. The tonality here is largely determined by the DD-BA junction: frequencies and the relative intensities of the implemented crossover.

Omg, the CCA Polaris is seriously good! The balance, the refinement, the spaciousness.. This is not a $20 IEM.

It's not a bug, it's a feature! ...

Since the influence of electromagnetic waves from telecommunications (phones or, as you said, BT headsets) on these calcite microcrystals in the pineal gland and possibly melatonin metabolism is not yet we'll understood, we jokingly just could assume that either BT headsets make you wanna sleep (increaseing melatonin release) or they just wake you up by reducing melatonin.
Interesting topic though.

They look the same to me. Maybe there is another layer of nylon filter inside that I cannot see.

Intrresting graphs. I would suggest to look at nornalization first. If dB values are correct (and they should be) the non-normalized graph for the red nozle should be higher in magnitude/intensity. Software then likely normalizes all graphs by default to the same intensities at 1 kHz or lower.

The graphs are not re-aligned at all. I intentionally lock the amp volume to see exactly what the dampening does. Normalisation would give a more accurate picture of the audible effects of the tuning.

Anyhow, the nozzles sound exactly like they graph. The red nozzle (no dampening) is the mildest ones. The gold nozzle with a thick o-ring inside (a weird dampening technique) sounds too deadly for my taste.

Yes I concur: a fascinating debate, whether they'd ever publish empirical data regarding any detrimental affects (e.g. calcifying of the pineal gland etc) is highly improbable.

Last night cancelled ST7 & tips combo order - in preference I've just ordered Hydro from HiFiGo - tbf they were the only set that could possibly get a rotational look in with the Delci & Rhapsody...so it's all good. Once I'd got used to the fit of the latter last week - & also considering how much better they sound post burn-in...Hydro are a no brainer !!

Howdy folks,

Simgot EA1000 review is online on head-fi and my blog.

Spoiler: tl;dr:

I must admit I come into this review with very high expectation due to the reputation that preceeds EA1000. I’m glad go say that I was not disappointed. EA1000 is an accomplished DD-based IEM with a “special sauce”: the uncanny out-of-head imaging with many recordings, possibly thanks to the passive radiator. Beyond the sonic performance, EA1000 also scores high in terms of the accessories and overall packaging. In overall, it’s an impressive “mid-fi” IEM.

Should you get EA1000? As usual, it depends. You need to answer to yourself: how much do you like/dislike the tonal balance of Harman IE2019 target and the IEMs that are tuned closed to it? If that sound signature is your favourite or at least does make most of your music library sounds fatiguing and shrill, then EA1000 is a good option to consider. I also see this IEM as a perfect spot to pause on the gear upgrade “climbing.” Give it a good dongle, find the most suitable ear tips, change to a nice looking 4.4mm cable, and you perhaps you can stop thinking about upgrading gears for a while.

What I like about this IEM:

• Uncanny, out-of-head stereo imaging with the right tracks
• Bass texture
• Good instrument definition and separation
• Great design, build quality, packaging

What could be improved:

• Small shell and short nozzle can create fit challenges
• Harman-ish tonality can sound shrill and strident with some vocal
• Tuning nozzles work but are not useful

Absolute Sonic Quality Rating: 4/5 - Great

Bias Score: 4/5 - I like this IEM!
