On the opposite end of the spectrum to the CKS5TW, we have this. Man, Audio Technica really knows how to diversify!
I honest-to-god thought that the CKR7TW I listened to broken at the start. It sounded like I was getting no seal, or that maybe the midrange driver was broken (in the daft assumption that it was a multi-driver setup), or perhaps something had gone awry during the pairing process and I had gotten a monstrosity of a sound thereafter.
Shoved it into the microphone and had all my questions answered with matched channels. Nope, the CKR7TW was meant to sound like this. A shrill, sharp, sibilant mess with zero thickness and weight in the midrange, sounding closer to a pair of blown out tweeter speakers than anything resembling a properly tuned IEM. And despite all this, despite its sheer emphasis on the upper frequencies, the CKR7TW struggles to extend beyond 10kHz and presents virtually zero air into the mix.
Yep, the direct opposite of the CKS5TW. Your options are endless.
