After nearly 2 months of wait (as always, thanks to notorious Indian customs office at Kolkata), got my **** 4in1, this morning (bought from AK store in AliEx for 28 US$ with stock silver cable).
OOTB (with stock medium sized red core tips and stock silver cable) using Wynk App in OnePlus One at 30% volume, tried listening to Michael Jackson’s Number Ones (320 kbps streaming audio) for an hour.
As experienced by few before me, I too feel the treble in these are way too hot to handle (simply unbearable, headache inducing and bordering on fatigue inducing levels for my ears). Otherwise, everything else seems pretty fantastic (vocals are bit recessed but the overall presentation does have an amazing imaging, detail retrieval, instrument separation, and a very well controlled bass) for my ears/gears. Just wish the hot treble was somehow reduced.
Just A/Bed HLSX 808 (my favt IEMs) to 4in1, found the former to be matching to my taste better than the 4in1s. With tip rolling and more usage, I hope 4in1s troublesome treble reduces (or at least my brain adjusts to it). At the moment, I doubt, I will be using these for long hour listening sessions (or giving it any listening time at all in its current sound). 4in1s are Off to burning station, now.
*These are just early impressions using the IEMs in its stock configuration, so take it with a grain of salt.
