Massdrop x Sennheiser HD 6XX Headphones

The HD 6XX is an open-back, over-the-ear design, and it’s very comfortable to wear for hours at a time. It comes with a six foot long, very flexible, user-replaceable cable terminated with a 3.5mm plug, and there’s a 6.5mm adapter plug. Head clamping pressure against my ears was moderate, and the velour covered ear pads are just the right softness.

The HD 650 looks identical, but the real difference is the HD 6XX headband is deep blue and the HD 650’s is dark gray. The sound producing parts are the same. You can say that, both are the virtual twins.

While, talking about the sound, The HD 6XX is an open-back headphone, but it sounds more open and less inside the head than most open headphones. Therefore you can easily hear sound from all around you. On the other hand, the bass-midrange-treble balance is so smooth it might seem a little boring at first. But settle in with the HD 6XX and you’ll find yourself hearing more and more subtle detail in your music.

Besides that, the treble was blissfully free of harshness, and the HD 6XX sounds right with the volume turned way down low or way up.
