Depends on what you’re looking at but for wireless headphones, those are definitely high-end. Arguably the best sound quality you can get on Bluetooth headphones actually.
I do want to stress that even if you have shitty headphones and/or speakers, or if you’re using DAC over wired, FLAC sound quality will still sound excellent compared to 320kbps MP3s.
Will you be extracting the full potential out of the FLAC audio? No.
Will there be a significant difference regardless? Yes.
