Separate names with a comma.
That’s what they’ve been claiming.
There’s no vents on the 30095 BA body, nor passive crossover components. So I’m not too sure about what they could have changed internally to tune it differently. I would think if there were massive changes, they would have given it a new model number (like 30096).
My gut is telling me that “specially designed” stuff is just marketing fluff.
Why in your picture the black/black zsn looks like it has the vent blocked? In mine it isn't.
Here is mine
Those holes look close to the same size to me at least in that pic?
Silver is the best conductor of pure metals.
Actually, silver has a propagation index of 106. Copper is 100 and gold is 70. The benefit of gold is that it doesn't oxidize and silver and copper oxides 'can' have a negative effect on sound.
There are other theories on why such and such metals may have sonic signatures, but those are discussions for another day.
And yes, I have pure silver conductors: (Siltech LS-38 speaker cables) in my HiFi systems and I even have ICs made with very thin strands of 22k gold (Stealth PGS.) I got rid of my 3 pair of Audio Note~Japan AN-VZ pure silver (two 9s?) ICs, because at the time, I needed money.
ZS6 is still my favorite. With the proper EQ it hits levels of bass, clarity and soundstage no other KZ does. I find the ZSN good for $20 but I find myself picking up the ZS6 or QT2 every time I have to hit the gym and need the music to have energy.
Mine do not look like that. There is no vent in my black/black ZSN.
It’s totally blocked off, ie the plastic body was never drilled. Only my purple one is drilled.
So here we are again, with differences. Some with vents, and others with no vents. Some wired in phase, others wired out of phase. Were the vents tuned that way on purpose? Was it an unintentional QC error? Who knows, each one is like a Fukubukuro mystery surprise bag!
So if someone is writing a review, or a people are reading a random review, or someone is giving their impressions, or someone else is making a recommendation, how do we know that the ZSN person #1 owns will be the same as the one person #2 buys?
How frustrating is that? KZ, you’re killin’ me Smalls.
Didn't you read DocHoliday's post above? You must have bad hearing from ZS6 sibilance!
DocHoliday: ZS6 (sibilant, sibilant, sibilant, sibilant, sibi...…)
I figured out why every KZ ZSN looks different. They've decided to make every one of them unique with a different sound signature! Don't just buy one, collect them all!
@Slater Is there a big sound difference between the 2 ZSN?
Hmm still have not opened my purple one yet. Been having to much fun with bt20 and es4. Will open it up and compare to my cyan.
Really surprising that KZ would have QC problems. I mean they have it right on the box.
In September I have received a defective KZ bluetooth upgrade cable (v2). It was impossible to set it in pairing mode, so it was useless. I bought it from Gearbest, The "QC Passed" stamp was on the box, but it seems to be just printed like a kind of marketing slogan...
I made a video record about the defective cable to demonstrate the defect and - fortunately - Gearbest has sent a working one, which have a really good sound for the price. So, it seems like the KZ's QC is not a (very) serious one...
My understanding is that your Fiio X3iii is a bright-leaning DAP. How well does it pair (synergy) with your ZSN?
The ZS6 is still my very favorite as well.
Truth be told, I would absolutely love it if KZ offered the ZS6 housing with their new low frequency BA and the BA10's rich midrange.
Sounds like an idea for a new model.
In the meantime the BA10 has really grown on me quite a bit.
I don't know if I settled down or the IEM has but it really is a great IEM if it fits your ears comfortably like it does mine.
Also, it should be interesting if KZ uses their new low frequency BA in the new AS06.
