DT770
 
The DT770 is beyerdynamic’s answer to those who wanted a closed headphone with balanced sound with good isolation. It’s four versions are all good, but they have varying sound signatures. It has the most balanced sound amongst all three lines.
 
 
 
- 32Ohm
 
The 32Ohm model of the DT770 is closer sounding to the 250Ohm and 600Ohm models than it is to the 80Ohm model. The most striking difference is that they have far less bass than the 80Ohm model, but also are fuller sounding. The bass on the 32Ohm's is tight and controlled but rather light on impact. If I had to rate it's impact I would say it's like the DT880/250, but even less than those. The high while quite extended and detailed but has a slight edge to them, but not grating or strident sounding. All of the DT line (DT770-DT990) has a treble oriented sound, so the DT770 will emphasize this. Now the mids, while fuller than the 250Ohm and 80Ohm models, are there but still recessed to a degree. The mids are clear, detailed, and possess decent transparency. Now the soundstage is smaller than the 80Ohm and 250Ohm and has an "in your head" sound to it. The dynamics of this model seem slightly lower compared to the 250Ohm version, but it’s hard to tell.
 
 
 
- 600Ohm
 
This is the best model of this headphone available. It has very smooth treble in comparison to the other Ohm models and is even more extended and detailed. The treble also no longer seems to trample over the other frequencies, but is more integrated with them. The midrange on this headphone is far better than the other Ohm DT770 models. Because the treble has been smoothed out and toned down a little bit, the midrange has made a nice appearance and is also very transparent sounding with lots of detail. The mids are just right in my mind on this phone and the best of the DT770 line. Now the bass on these is full, has nice texture, and has more weight to it. It’s definitely more pronounced than its 250Ohm counterpart. Also the bass is much faster sounding on this model and is also deeper sounding as well. The soundstage is also bigger than the other three models and possesses nice depth, width, and height.
