CCZ KBEAR IEMs Earphone Cable 4 Core High-Purity Copper Headphone Replacement Wire with TFZ pins for KBEAR KS1/KS2/Lark, CCZ Melody/Coffee Bean/DC01 PRO/DC02/DC03/BC04 PRO Earbuds(without Microphone)

Good Cable, I believe they had been previously used in some KZ earbuds, will fit the ZST model. I prefer these over what they're currently including in some KZ products since the connection where the cables split is more robust. The trick for using these is to not extend them and properly put the right and left earbud on the right cable. Should last you a long time that way. Unless you have super hearing they're a pretty decent benchmark when it comes to something affordable and available.

The cable is light, making it comfortable to wear for extended periods without feeling heavy or cumbersome. The memory wire around the ear is flexible and molds well to the shape of my ear, providing a secure fit and reducing the need for constant adjustment. I do appreciate the fact that the cable doesn’t tend to overheat during long listening sessions, as some cables can become uncomfortable after a while. noticed an improvement in the sound quality of my IEMs after swapping to this cable. The most notable difference was the increased clarity and detail in the midrange and high frequencies. It brought out subtle nuances in both instrumental and vocal tracks that I hadn’t heard with my stock cables.

Works well for my needs for my IEM buds. Moderate length and do not feel flimsy.

These replaced the cords that got tangled in my vacuum. They work well. The sound is good. The other day I noticed a crackling when I moved the connector. I'm hoping this does not mean they are going to cut out. I will update as needed.

Perfect fit for my ZSN-Pro's. My old cable had broke and and I bought these as a replacement and they are wonderful. My only complain is that the connector is slightly looser than the original, and as a result cable slowly detaches and I occasionally have to press it back into place again -- but thats a really minor things.

There's 2 cables with mic in this listing that say they fit the KZ ZSTx IEMS. One just says Black & the other says White B pin. Looking closely at the connectors, the white B pin is recessed but the Black is not.Description for the Black says:CCZ KBEAR IEM Earphone Cable 4 Core High-Purity Copper Headphone Replacement Cable for KBEAR ks1/ks2/Lark/Robin/Rosefinch CCZ Melody Coffee Bean Warrior KZ ZST X EDX ES4 AS10 CCA C10 TRN V80 V90 IEMsDescription for the White B pin:KBEAR High Purity Oxygen-Free Silver Plated 2pin IEM Cable,HiFi Wired Earbuds Detachable Upgrade Cable for KZ ZST ZSR ED12 ES3 ES4 ZS10 BA10 AS06 AS10 ZSTX EDX CCA C10 Earphones (with Mic, B Pin)I've attached screenshots of the actual photos from this listing showing the Black (with mic) & the White B pin (with mic) connectors are totally different tho both say they fit the KZ ZSTx.Thee is also another listing selling the exact same Black (with mic) stating it's a TFN that does not include the KZ ZSTx in their description for what IEMs fit. I know this because I have purchased one & returned it for a replacement. The replacement was the same as the 1st. Being returned as well but making me wait 30 days for a refund!These ones from this listing will be returned for a refund as well as none of the BLACK cables fit the KZ ZSTx IEMs.If you're looking for a replacement cable for your KZ ZSTx IEMs, make sure its a true .75 mm B pin connector & not a cable that just says BLACK.I made these mistakes & wrote this review so you don't have to waste your precious time & hard earned money like I did!

the short story - if you bought CCA C10 from HiFiHear (HiFi 1DD 4BA Hybrid Five Drivers in-Ear Earphone, CCA C10) and the come with the clear vinyl coated cord with the white control button, buy this Cable 4 Core High-Purity Copper Twisted replacement cord. The difference is remarkable, even to these 72 year old ears.the long story - i bought the above-mentioned CCA C10 earphones a few months ago and they came with what appears to have been THIS Cable 4 Copper cord. I was blown away by the sound quality from the earphones, but soon began to notice that they "cracked/crackled". Bummer. I went on Amazon to get replacements and, if i recall correctly, when i brought the original ones to Whole Foods for return, the replacements were shipped. Easy Peasy.But when i got the replacement earphones, they had a clear vinyl cord. i was perplexed, until i tried out the earphones and was then majorly disappointed - they sounded like crap! I contacted HiFiHear to see about getting back the Copper cord, like the one i had returned, but they said couldn't be done, they didn't have any. i searched Amazon and found the Cable 4 Copper cord, which looked to me like the one i had originally received. I pointed this out to HiFiHear, but sorry, they didn't have any. I wish listed the Copper cord and finally ordered them bc i just couldn't listen to the earphones with the vinyl covered cord. I got the Copper cord a couple weeks ago and switched it onto the earphones about 1/2 hour ago, I am now listening to Peter Frampton, All Blues, The Thrill Is Gone, and very happy to report that the thrill is back! If you have the CCA C10 earphone, the $9 for this Cable 4 Core Copper replacement cord with be the best $10 with change you spend today. On to Going Down Slow...

Good quality cable. Though it doesn’t fit all the way on the Chu IIs. It’s just enough to make a connection, but it does get loose and disconnect.
