Knowledge Zenith (KZ) impressions thread

    The newer one that he is talking about is balanced on both sides. There are other options, just search on Aliexpress for MMCX bluetooth. No experience myself but heard that these are ok https://nl.aliexpress.com/item/2018...6130-4882-90e6-7a0046ceb695&priceBeautifyAB=0

    Well put sir. Solid (and true) advice.

    There is absolutely zero guarantee that X or Y driver or configuration will instantly = good sound.

    Now, if the OP is looking for a single BA because they are typically super compact in size, and thus good for specific purposes like sleeping, then that is another story. But then again, a micro dynamic driver can be pretty much equally as small as many single-BA IEMs.

    But like you said, it all boils down to the end result (the sound). That's where the rubber meets the road.

    Not surprised, with 2000 pages, I probably missed a lot more than that.

    I think the issue with KZ is that creating a single full range BA is way more complicated than tuning an existing one. it is far easier to use dampers, capacitors and resistors to modify the sound of an existing driver than to alter the basic design to perform differently. Even big names like Noble are having their custom drivers made by Knowles and Sonion because they know when to leave that to those who know it best.

    If they cant tune a driver, the likelihood they can create a solid full range BA is almost zero.

    They are still produced by Knowles, sonion or molex(final audio) but on special order and specs and their isnothing like in house BA

    well the reason i was looking for a cheaper single BA iem because i wanted to get listening experience from BA only iems as i had never listened to one i try to guess how the bass will be from these kind of iems

    just wanted to experiment :p

    I know this are supposed to vary by person, but could you share your ES4 Neutralizer profile :triportsad:

    Very thanks for this link. I honestly couldn't find when I searched.

    usually one should set the frequency volume to minimum threshold but i experiment with this equalizer by relatively increasing certain frequencies to listen to their effect on sound
    but yeah setting the frequencies to minimum threshold is the way to go

    This one is the least expensive single BA that I can find. If you search the forum, there is some discussion about it. The Astrotec AM90. I think it has been around for a long time. Knowles Single Balanced Armature Driver.

    I'm gonna stay far from these then
    I'm just really curious to hear how they sound as many people reported amazing reviews

    Now i'm really confused.. i like the shape of the zsa, it seems very little and could easily fit my ears. Then i even think about tin audio t2, about spending some more for them

    What would you tip me?

    The thing to remember with any driver whether BA or dynamic is that efficiency is diametrically opposed to extension. The only way to create a full range driver with good extension at both ends is to sacrifice efficiency. The fact that the Astrotec shows really good efficiency numbers suggests its extension will be lacking. The Campfire Comet on the other hand has an efficiency in the low 90s and an impedance of 48 Ohms as they were shooting for more extension at the expense of efficiency.
