First thing I will say, WOW. Just WOW.
So I have used FH1, RHA ma650
Source OnePlus 5t - tidal - q1mk2
Sound quality is just brilliant.
I would say these are a breath of fresh air.
If you like to listen songs sitting near a pond in a green park these would be my preferred drivers. (weird comparison? Trust me I know!)
I will not go into technical details, that you can find on the Hifinage page.
Just my experience.
Sound stage, Sound stage, Sound stage. So much soundstage very nice.
Just so much space created by these drivers
You can spread a live performance inside you head even with your eyes open.
Bass and sub bass Is brilliant not punchy. You could say it's the amount intended by artists.
And of course you can tweek that by dacs and equalizer
Mids are very well defined nicely separated from bass.
Details in the instrumental sound is very noticable
Highs are pleasant and not piercing at all.
Guitar strings and symbal sounds are so clear seem like they are being played in front of you.
My first open back and what an experience. Openness should be a top selling point I would say.
Just love their sound signature
I mean I was in aww after listening FH1 I really liked the wide sound stage.
But the Soundsly definitely have worked their hearts out in making their first product.
Love it.
