ROSESELSA QT9-MK3, 1DD+4BA Hybrid In Ear Monitors, HIFI Wired Earphones with Detachable IEM Cable

I was not expecting too much as not popular or expensive one..
But this one is awesome! Great bass that not quantity but quality both sub and midbass.
Mids, vocals and instruments are creamy soft and not v shape as forward as bass and treble.
Specially Layering and seperation is unexpected. Delicious.
Upper mids are not elevated as most iems that makes very listenable this iem longer times.
Especially for treble, in first you miss some quantity, yes treble tamed a bit but this is not a roll of, this is one of the best treble I have ever listened very technical, airy like stardust.
Only the concern can be stage, a bit intimate.
In summary for this price this is a no brainer! Great work Rose technics, congratulations!
