The Beyerdynamic DT770 Pro Headphones come in three flavours, designed for three very different and specific applications. With its rating of 250 Ohm, this particular iteration of the model is purpose-designed to bring high-quality audio to mixing applications in the studio. With this function in mind, these headphones have been crafted to ensure the comfort of the user through even the most lengthy of recording sessions, without fatiguing.

The Sound of 250 Ohms

Designed for studio-quality sound referencing, and with an exceptional bass response, the Beyerdynamic DT770 Pro Headphones deliver, with high impedance and accurate response. They also allow for multiple headsets to be used safely from the same source, as they are at a much lower risk of blowout than headphones with lower impedances.

With their higher impedance, the Beyerdynamic DT770 Pro Headphones (250 Ohms) offer clarity to your referencing but are quiet, making them perfect for studio use, as they can be used in combination with a decent headphone preamp that are usually included with mixers and mains-powered audio interfaces.

Close or Open Back?

When choosing a pair of headphones, application is key. A pair of closed back headphones are best for recording, as they keep all the captured audio in the headphones, with no spill that could be picked up by your microphone. The issue with this is that when mixing, it can affect the low end frequencies and some bass response can be lost.

Open back headphones are best suited for mixing, as they allow for clear bass response and a more natural sound, as sound can spill through them. The problem here is that if they were used for recording this audio spill could be picked up by your mic.

Baby Got (Closed) Back with Bass Reflex Technology

The answer here is to either buy two pairs of headphones, or more preferably, get yourself one pair of Beyerdynamic DT770 Pro Headphones (250 Ohms). With their Bass reflex technology, bass response is improved with a nominal frequency response of 5Hz-35kHz. This gives you the isolated, non-audio spilling of closed back, but with the clear bass response of open back.

Also, with the headphones’ large cup sizes and velour cushions, air can be let through for that natural sound, but sound is kept within the confines of the headphones.

Posted on 20/10/2015 by The lows are punchy and tight, the tops are clear and open and the mids don't even sound slightly harsh. The only bad thing I can say about these headphones is that you have to be careful what you're powering them from as matching up with the wrong equipment can leave them sounding a big empty and lifeless.
