Tech Review: Massdrop X Sennheiser HD 6xx

TLDR (too long didn’t read):


  • For its price nothing compares to its sound quality
  • Vibrant and exciting sound
  • Comfortable
  • Open-back


  • Bulky
  • The sound is not the best when using your phone/ipod
  • Open-back (no noise isolation)

When Massdrop announced that they were going to do a collaboration with Sennheiser I was extremely excited about it. Not to mention, they’ll be redoing the iconic Sennheiser HD 650s. If you are wondering, “What is the Sennheiser HD 650s?”, it is widely known in the audio community for being the best headphones in town. So when Massdrop announced the ‘drop’ their whole site essentially crashed as so many people wanted to get their hands on this pair of headphones. I was one of the lucky 5000 people who manage to get into the drop. (YAY!!!!)

First of all, I would like to start off with the un-boxing experience. It was A-M-A-Z-I-N-G. After opening the box, you will be greeted by this sleek hardcover box. When you open it, you can instantly tell that it was a good 200 dollars spent.

These headphones have a very dark royal blue colour to it (honestly, without good lighting it looks black to me). Looking from its side, you will see the sound drivers inside which looks extremely sexy. The headband is cushioned very nicely and it is complemented with velour ear pads. Personally, I don’t really like the velour ear pads as they tend to attract a lot of dust which I have to regularly remove; but maybe where you live isn’t as dusty so it may not be a problem. The whole construction of the headphones is essentially plastic except the adjusting band which is made out of metal.

Now on to the sound quality. After using it for about a month or two, the headphones have definitely been burnt in. It has decent bass and low end, with really good mids and highs. The few main genres I personally listen to is pop and EDM and sometimes classical. They actually sound pretty good. It is quite detailed as compared to when you use a lower end pair of headphones where you aren’t actually able to differentiate the various instruments and sounds because they are mushed together or just aren’t as defined. With this pair I really enjoyed listening to it. I am also able to use it for hours and hours without getting fatigued as the clamp pressure is not too hard and it is quite comfortable on my head.

In conclusion, for 200USD (around 280SGD*) this pair of headphones is a steal. It’s one of the best that I have heard that would not burst your bank account. However, I am not sure when Massdrop is going to be selling these pair of headphones again. If you manage to get hold of one of it, I’m sure it is worth the amount that you are paying.
