Does the job as intended and sound is clear and loud, a bit too loud though. At night I'm on the lowest level using my phone. One more and no sound. Ok for pc where i get both player and system volume control, but iems on Android, just a tad too powerful.
Worst offender though is that shielding is bad and to have a decent playback, i have to turn off both data and bluetooth else a lot of static.
Actually even with all radios off, playing through native music app, still this clicky sound that just irratates you.
But hey, quite cheap solution for adapting a usb c to a headphone jack. Used with shure se425 and fiio fh5 (both not the most critically sensitive iems so the clicking sound and static is a pain and shouldn't be an issue)
