Frequently Asked Questions (FAQs):

Looking for some answers to your problems? well, worry no more as this section is going to solve some of your problems throughout this process.

Can you use the HD 650 effectively on an airplane?

The HD650s are not noise cancellation headphones and inferior to Bose, for instance, when using on a plane. In addition, the HD650’s can be heard by others because of the open design. They are superior to everything else for solo listening when you are not on a plane.

For studio recording and mixing, would I need to get a separate headphone amp and DAC? Or would a Baby Face audio interface suffice?

Not necessarily true Vincent. Out of a computer, then probably yes. But the question is about an external, fairly high-end RME Babyface audio interface. So it is not out of the computer directly. However, the Babyface is geared for 30 ohm and not 300 ohm, so a headphone amp would be beneficial.

Since there are vents on the sides does the sound leak? Can others hear it?

These headphones are a semi-open-back design. They sound much airier and natural compared to the closed-back kind design. However, on the downside, they do leak to some extent, especially on higher volumes. Others will be able to hear the higher freq. but will not be able to distinguish what is being played.
