Before You Buy A Sennheiser HD6XX, READ THIS!!

Part of the “Before You Buy” Series


Is the 6XX identical to the 650? How does it compare to the original 600? Why are you talking about this headphone yet AGAIN?! All of these answers and more, comin’ up…

Greetings bass head and Welcome aboard… Stuart Charles here, helping YOU make sound decisions leading to a beautiful audio experience that will make you fall in love with music, all over again soo…

No, the 6XX is not identical to the 650, and now I have verifiable proof. Shout out to José Pedro for his wonderful comment on my first HD6XX video: Let’s take a gander:


Happy New year Stu!. I hope that you are doing well. I guess that you know that issued recently the results of the tests of the Sennheiser 6xx. Unsurprisingly it scores very high…but surprisingly the results are different from the HD650, concluding that they are not exactly the same Headphones. So once more it was proved that you are a pioneer, my friend!. You were the only one among all reviewers who always said that the sound profile of the 6xxs was not identical to the HD650 :-). José Pedro

Unquote, and it’s not.

Video Discussion

Thank you, José. Absolutely correct. No matter what you think about the graph, it still proves that they ARE NOT identical. People have been trying to argue with me about this since I first dropped the original shootout video, but guess what, they’re wrong! So anyone who tells you that the HD6XX is identical to the HD650 is LYING!


I’ll say it again and keep saying it: The 6XX does not sound like the 650. It’s a perfect balance between the too forward 600, and the too syrupy/laid back 650.

I thought this was perfectly obvious when I demoed it.

But apparently, it wasn’t according to some fake wannabe audiophile snobs who like the smell of their own farts. HAHA!

Go ahead and click away if you’re one of those types who got triggered. Let the world know how you feel. Comment too! It’s not outlawed yet.

The 650 tends to be too smoothed over and warm. I likened the comparison of the 600 vs. 650 to be similar to the analogy of wood vs. sanded wood. The 650 sounds like wood feels after it’s been sanded and polished. The 600 is a raw piece of wood without any added enhancements, like your girlfriend fresh out the shower (That one was for you Prabin).

The 6XX sits squarely in the middle of those 2 things, meaning it’s a perfect sound.

So stop arguing with me alright?!

As for the question of why I’m talking about it:


This is my blog and I’ll do what I want. Now if your ruffles were feathered, go ahead and drop a mean comment, and while you’re at it…


Haha just kidding.
