Beyerdynamic DT 770 PRO, 250 ohms

0

Introduction

Inspired by Beyerdynamics’ classic ‘80s models, the Beyerdynamic DT 770 PRO is a polished, practical, does-what-it-says-on-the-tin kind of headset dedicated to loyal fans. With Tesla technology, these ‘diffuse-field equalized headphones follow in the footsteps of the DT 990 and 770 developed in 1985 for audiophiles and sound engineers alike. This German company was founded long before Sennheiser developed their first headphones, but these two have been going toe-to-toe to conquer the global market ever since.

Beyerdynamic envisioned the Beyerdynamic DT 770 PRO 250 Ohm headphones as a premium studio mixing headset accessible to those who don’t have an urge to splash out, but still want their headphones to be all they can be, in any professional music environment. While the DT990 were fully opened back, perfect for critical listening, and the DT 880 PRO were ideal for reference monitoring and mastering, the DT 770 was aimed specifically to those who are interested in studio and stage performance monitoring. Whether or not the 250 Ohm fits the bill is something we aim to touch on in our review below.

Build Quality & Design

The Beyerdynamic DT 770 PRO is made using a classic design, and they only come in black. The velour earpads are silver, but they can be replaced with black sheepskin pads, or covered with black pad covers available on the company’s website. Both ear pads are comfortable, breathable and wearable for hours on end. All parts are replaceable, but keep in mind that damage to the cable is likely to mean that the entire headset may need replacing.The headband and the earcup chassis are made of steel. The ear cups themselves are plastic, and the earpads are coated in velour.

The headband and the cushioned pads are removable. Beyerdynamic offers leather coated pads, as well. The earcups swivel for a tighter fit, and the cabling is in the exterior, so that you needn’t worry about breaking the connectors as you extend the headband.Unfortunately, although the 3-metre cable is coiled as you’d see with old-fashioned telephones, it is also non-detachable. It terminates in a classic, gold-plated quarter-inch plug adapter over a 3.5 mm mini-jack plug. However, it is single-sided, so that makes your headphone easier to handle.

Sound Quality

These headphones are all about the bass. Lower frequencies are enhanced, but smooth. The wide frequency spectrum, from 5 to 35,000 Hz, allows this headset to go deeper than most others you’d ever stumble across in this price range. Progressive metal, jazz, and even electronic music sounds clear and crisp. Even pitchy or blurry female vocalists seem to shine on these headphones. For those who prefer highs, some equalization is in order for dimensional sounds.

At 250 Ohm impedance, this headset requires the greatest amount of power in this line, which also includes two other versions, the 32 and the 80 Ohm. In other words, you can only expect the 250 Ohm DT 770 PRO to be the best it can be if you couple it with an amp. Without the juice to allow the driver to move, the entire treble range will be compromised. Still, if you don’t mind having lower trebles, you don’t have a portable amp, and if you’re not particularly interested in the bass, then this DT 770 PRO version will do just fine with any notebook that has a good soundcard, a decent smartphone or an MP3 player.

With poor performance sound-cards, such as those you’d see on a Mac, the DT 770 PRO can still perform to the full if you extract and drive the sound to an external soundcard.As expected with any closed-dynamic headset, this one reduces ambient noise passively, but it also gives you a sense of experiencing sounds in your head, rather than through your ears. It’s normal for these and all other closed headphones to emphasize the lows in favour of the highs, so do keep that in mind when you scout for the perfect headset.

Features

DT 770 PRO comes in a simple, no-frills cardboard box and a drawstring bag, which is a shame, because you’re likely to be want to be very protective of these headphones when you carry them around. They may be 270g heavy, but they’re still optimal for light travelling. Still, if you need to carry them safely, there’s a matching nylon transport bag that you can buy from Beyerdynamic, along with sheepskin cushions, ear covers and extension cables.

The transmission is wired and the headphones operate in closed circuit. Beyerdynamics backs up the closed diffuse-field capabilities with ‘bass-reflex’ technology for optimum bass response.

The nominal sound pressure is officially 96dB, so they’re quite sensitive. They’re officially sound monitoring headphones, so you shouldn’t expect anything less than great sound pressure. We should note that while the 32 Ohm version was designed for mobile applications, and the 80 Ohm version was created for studio recording, the 250 Ohm was made specifically for mixing, so keep that in mind when you try to find the best version applicable to you.

Verdict

Whatever brand of headphones you used before the Beyerdynamic DT 770 PRO, you could only go a step higher when you decide to buy this headset. These closed dynamic headphones are classic, true to Beyerdynamic tradition in audio solutions, with a rugged, no-frills build, a straight, bass enhancing and immersive sound, and a clear sense of multiple dimensions with details rushing at you from every angle. There’s really nothing that detracts from the sense of perfection here, aside maybe from the fact that the cord is not replaceable, but given the sturdiness of the headset, damaging it in any way would be a tall order. In a nutshell, these headphones not only deliver, but they even exceed expectations.
