Cubilux USB Type C to 0.78mm 2-Pin IEM Cable with Detachable Boom MIC, 4 FT

TL;DR: quiet microphone, likely capable of driving most IEMs on the market to audible volumes, cheap construction but undercuts alternatives solely on price. Properly shows up as a USB audio device with VID 31b2 and PID ff11. Could not find anything specific with this VID & PID but this VID is associated with KTMicro, which is a Chinese manufacturer. Thus, the actual specs are a mystery. The listing is accurate to my knowledge, with supported output format of up to 192 Khz/16 bit and up to 24 bit for 96 Khz/48 Khz/44.1 Khz sample rates. The microphone input is up to 48 Khz/24 bit audio format. In actual usage, I found the microphone to be pretty quiet. The combination of short boom length that doesn’t quite reach my mouth along with the generally low gain of the mic makes things sound really quiet. The microphone enclosure only has a single opening at the end that points outwards. Without any additional length to work with, the microphone can’t really point towards my mouth and thus I’ll always sound slightly muffled and quiet. Since the audio input isn’t very loud to begin with, I doubt it’ll pick up much background noise but it would definitely be suggested to speak louder than normal for better mic audio. Without having any specs provided regarding how much power the DAC can provide to IEMs, I can’t comment on what pairs can be driven. But I tested with a pair of 7HZ Crinacle Zero 2 IEMs and I needed to turn the audio volume way down below halfway to around 15 in Windows. I think this cable should be more than enough to drive most IEMs on the market to audible volumes. I did find the cable to be very cheap and flimsy. It easily gets kinks in the cable and overall doesn’t feel great. Compared to other alternatives on the market, these stack up fairly nicely solely on its pricing because this product undercuts everyone else I’ve seen. Options from Kinera and Antlion (off the top of my head) are a sizable amount more expensive and offer basically the same functionality.
