The bad

    They are not the best in noisy places



Some of us still want some headphones that sound great, regardless of whether they have cables or not, and we are willing to spend a decent amount of money to get them. The good news? You don't have to break your piglet to get some of the best headphones that money can buy.

The acclaimed audio brand Sennheiser has produced a good dose of success among the headphones, but its HD 650, frequently considered as one of the best headphones in its class, stand out.

More than a decade after its debut, the HD 650 have undergone a renovation (more or less), and you can say they are better than ever. This is embodied by the HD 6XX, the result of a collaboration between the legendary brand and the audifilo subset of the Massdrop business community.

Massdrop, now known simply as Drop, has modified some of the characteristics of the 650 to provide them with a better ease of use, with the very low price of $ 220 dollars.


When the HD 650 debuted in 2003, it easily cost more than $ 500. And although the price has plummeted for the 6XX version (same as for the original 650, in most of the sites), that does not mean that potential buyers will not receive a taste of true audifilo luxury. That experience begins with a massive black thick cardboard case, which is filled with a large hard foam bed and boasts a shiny black Sennheiser logo on the lid.

Inside, the headphones rest in their foam bed, protruding like a pair of oval donuts, attached to an adjustable hinge and covered with a dense metal mesh that reveals the interior. In there are thick cushions covered in the same acoustic silk that provides sumptuous comfort in the HD 650, and also boasts a bright acoustic seal. A Sennheiser logo on the headband assures you that what is inside is of high quality, and few details reveal the new design of the HD 6XX.

In principle, the most noticeable change in design is color.


However, when examined more closely, some improvements that distinguish 6XX are revealed. In principle, the most noticeable change in the design is the color 6XX change the carbon gray of the HD 650 to an intense black, with lines along the edges in a subtle shade of dark blue (you probably need sunlight to see them).

Perhaps what most attracts attention is that the removable cable now ends in a 3.5 mm plug instead of a 6 mm. (includes a 6 mm attachment), detail that makes these headphones much more versatile for use with all your devices.

The cable length has also decreased by 3 meters, distance suitable for a study, to 1.8 meters. The total weight is 260 grams and these beauties cling tightly. That is softened by the soft pads, so it is easy to use the 6XX during long sessions.


In figures, the HD 6XX proclaim an impressive frequency response of 10Hz-41khz, unheard of for headphones that cost much less than $ 500 dollars.

If you have already listened to the HD 650, you may want to skip this section and go directly to the link of Where the hell I bought them! down. If you've never heard them, a delight awaits you with the best sound that dynamic controllers can offer at this price and more.

Specifically, we refer to low cliffs and rigid, a medium range that is very close to the crimsons of the saturation of the analog tape (without sacrificing a pinch of details), and an impeccable response that illuminates a vivid clarity and instrumental texture granulate throughout the spectrum. So, they sound great.

Especially in the bass and mid-range, these headphones enjoy the scratchy texture of the electric tones of the 70s guitars and crispy B3 rganos. But they are equally capable of revealing the subtleties of each original recording, leaning towards the cold detachment of a Depeche Mode style melody. The ability of the HD 6XX with details and presences accommodates all the textures and instrumental timbres that an audifilo can crave, particularly well delineated in the effervescent breaths of a saxophone legend or the subtle scratches of a horsehair bow through The strings of a violin.

In addition to that beautiful sound signature, the HD 6XX offers an open sound stage. The open cover design distributes the sound waves perfectly, allowing the instruments to extend beyond the few centimeters between the ears and expand into a single cloud around your head. The result is a sound that is surprisingly similar to sitting in front of a good pair of studio monitors, or even sitting in the center of the recording room. That entails the virtue of hearing things you've never noticed before in your favorite songs, from the rebel buzz of a guitar amplifier, to a silent double vowel that had never appeared before.


The HD 6XX comes with a two-year warranty for parts and labor, backed by Sennheiser.

The HD 6XX are a very welcome and well executed second generation of one of Sennheiser's best products, and represent the opportunity to make a sound for headphones accessible for a very good price. These are, without a doubt, the best sound headphones we have heard for $ 220 dollars. They easily compete with products that cost many multiples of that price. If you are looking for the best possible sound for your money, these are the best you will find.
