The Full Story
LoveBar's deep-dive, written for humans 💕
This is a showdown between two German audio houses that have been perfecting the art of open-back headphones for decades. The DT 900 Pro X is Beyerdynamic's modern take on the studio reference headphone, delivering a soundstage so wide it feels like the music is being performed around you rather than inside your head. That spacious presentation makes it a favorite among creators who need to hear exactly where every element sits in a mix. The HD 660S2 takes a different approach, pulling you closer to the music with a warmer, more intimate presentation that makes vocals sound like the singer is right in front of you. Sennheiser's tuning has always had this magical ability to make everything sound musical rather than technical. Both headphones are purely wired affairs with no noise cancellation, designed for focused listening in quiet environments. If your priority is accuracy and space, Beyerdynamic is your headphone, but if you want to fall in love with your music collection all over again, Sennheiser has that special sauce.
