[Acutual review] beyerdynamic DT250 monitoring headphones

In recent years, regular headphones, like the T1 2nd Generation equipped with Tesla drivers from beyerdynamic, have found a place in the Japanese market.
However, globally, beyerdynamic is a standard studio headphone brand alongside Japan’s Sony. Beyerdynamic can be found at the famous Abbey Road Studios, and if watch music videos by many foreign artists, you'll see quite a few beyerdynamic headphones.
Generally speaking, the standard beyerdynamic studio headphones in Japan are the DT770PRO and DT990PRO. However, this time I would like to focus on a more professional headset from beyerdynamic, the DT250.

beyerdynamic / DT250 80 ohm

At first glance, the beyerdynamic shape is similar to the classic SONY MDR-CD900ST, primarily available in Japan, so I compared the DT250 with the MDR-CD900ST.

The DT250 is slightly larger.
And it is almost all black.

First, the major difference when compared with the MDR-CD900ST is that the DT250 has a detachable cable.
The connector is unique to beyerdynamic, and re-cabling can be difficult, but it is good that you can replace the cable in the event that it gets shorted or snaps in two!

The included cable is a curly cable with a conversion adapter, making it convenient for carrying around and using with a variety of devices.

The DT250 ear pads are much thicker than those of the MDR-CD900ST. As they are made of cloth, the touch is very nice. The lateral pressure is higher than that of the MDR-CD900ST, but this improves the sound insulation quite a bit. I wear glasses, but even then, the lateral pressure on the frames does not create any pain or hurt my ears. The fit is quite comforatble.

And the headband! The DT250 headband pad can be replaced, if it deteriorates over time.
This is a feature of beyerdynamic headphones that is similar to the MDR-CD900ST, in that, basically, replacement parts are available for almost all parts. So when you think to yourself, “I want to replace the headband pad because it’s worn out”, or “The slider is broken”, you can replace the parts.
That may be one of the reasons why beyerdynamic headphones are preferred overseas.
You can use the set of headphones for a long time just by replacing parts instead of replacing the entire set because one part broke.

Finally, about the sound quality,
This time, for comparison, I watched a video by Tame Impala, who recently released a new album, The Slow Rush. Cool as ever. Even though the same phrase repeats over & over again, it changes subtly each time, making it more & more addictive if you keep listening to it.
Listening to it with the DT250, the stronger lateral pressure seems to emphasize the lower frequencies a little more than the MDR-CD900ST. Because the sound resolution is solid, the swaying synth with the flanger effect applied and the vibrating deep bass are well separated. The mid-high range sound quality was slightly sharp, but with no piercing sensation, and Kevin's voice was clear. I think that you won’t easily get tired using the DT250 even if you’re monitoring for an extended period of time. With the MDR-CD900ST, the mid-high range was somewhat crisp, making it felt like the touch of the hi-hat and the sound of percussion were closer in proximity than other instruments.
The DT250 sound spread also feels a little wider than the MDR-CD900ST. After all, isn't it good to get an overall balanced sound?

Why don't you compare the DT250 with your favorite headphones and see which set you like better?
