Hey guys, I have a question for KZ ZSX owners, do you have some bad hiss when playing music? it's pretty noticeable on high volume especially when I compare it to my KZ ES4
Hi I made a post about this hiss issue a few weeks ago:

At Nirvana unplugged I noticed a certain sharpness by zs10 pro. When I lower at 2500 Hz 1-2db, the zs10 sounds much more pleasant

reducing sharpness by applying low freq shelfing? that's odd.. what sharpness are you referring to?

Probably I do not know the optimal words in English for what I mean.
Anyway, Curts voice, as well as the acoustic guitar, often sounds uncomfortable in my ears.

With the settings described above, it gets much better.

I am probably very sensitive to these frequencies.

no problem, audio lingo can be confusing sometimes :ksc75smile:
usually sharpness is associated with treble region. from what you did to your ZS10 pro with EQ, it seems like you're reducing all low frequency up to passing the vocal and guitars fundamental freq. it looks to me the ZS10 Pro just has too much bass for your taste

I've got audible hiss from most sources with the AS10, ZSX, and ZS7(to a slightly lesser degree). It's due to sources not having low noise floors at the low power needed for these IEMs since they're high sensitivity and low impedance. The hiss is nearly completely gone if I use the ifi iematch/earbuddy with those sources, or completely gone if I'm using my ES100 as an amp.

This is one of many reasons why I keep singing the praises of the ES100.

Best money I have spent in this hobby in a long time.

Radsone should just make a Fiio M5 competitor that can also store and play files in addition to the bluetooth. Do we have to come up with everything. This should exist already:)

This ES100 device is a complete mystery to me. It's like a Swiss Army Knife of Dark Arts and Magic. Does it hold any benefit to someone who has a DAP (Fiio) and a DAC (Dragonfly)?

If you have a need for a wireless solution, or if you want a convenient way to add EQ to your portable chain without needing to do it in software.

I sent them this as a feature request/product idea a while ago.

More precisely, I said they wouldn’t even need a screen. All they’d need to do is add a microSD card to the existing ES100. Everything would be handled by the app, with the app controlling the actual media selection and playing, album art, etc. And of course the EQ and other existing features would seamlessly integrate into the app as well.

Basically, the ES100 would be used for local media storage and processing; no screen required. The sound would be optimal, because it’s directly wired (ie no Bluetooth when listening in ‘local media’ mode).

Yeah, a headless DAP/streamer along the lines of the Chord Poly (but with EQ and better app support) would be 10/10 for me as well

the ES100 would be much more compact and lighter. i used to pair a DFR to my phone, but i don't use it anymore because of the hassle and it's more prone of breaking (i like to still use the phone while listening to music).

the ES100 itself has a soft natural sound, similar in tone and level of sound quality to the Dragonfly Black, but with the added benefit of great app, balanced jack, dedicated controls, and also you can leave the phone charged on the desk while using the ES100.
