These are amazing sounding and fitting IEMs. I think their an easy recommendation at $269.00. This the music I used to test with: Malia - Unfastened Piano at beginning, symbols at the end very subtle and beautiful
Greta Van Fleet - "Highway tune"
Guardians of the Galaxy Awesome Mix, Vol. 2-
Mr. Blue Sky (ELO)
The Chain (Fleetwood Mac)
Bring It on Home to Me (Sam Cooke)
Beyonce - Hold up
John Coltrane - A love supreme part 1
Eydie Gorme - Los Nosotros (made it sound better than any other IEM)
I found that these were detailed with great bass. The Mid's were outstanding and to my ear vocals were a bit forward. Don't use the gold filters they block to much sound. Treble was back, but present, and very detailed. These compete with Audiosense AQ3 and are better in some respects. They are at the level of the Fearless S8Z in how they smooth the music out.
