iirc the 1650 and 1670 measure very similarly outside of a few db at the treble
Lucky you...I almost cant get acoustune to sit in my ear properly. The shell always rubs against some part of my ear. Acoustunes definitely look damn good though, I'm a fan of the red+gold 1551 and your black+gold 1650. Enjoy them!
Thank you very much. Frankly the fit isn’t the best or rather my fav such as those of StageDiver type mould, however it seems to sit okay in my ear =]
