How will they compare? Will I notice a large drop in volume level? I run my headphones from an NI Audio 8 DJ interface.
Beyerdynamic DT 770 Pro (80 Ohm)
Impedance: 80 ohms
Nominal sound pressure level: 96 dB
Sony MDR-V700DJ
Impedance: 24 Ohm
Sensitivity: 107 dB
Hey mate,
I see you've already had a listen yourself to the 770s now, just wanted to chime in my thoughts.
I too had a pair of MDR-V700DJs since around 2003.
Haven't listened to the 770s (closed-back) myself, however, purchased the 990s (open back) around 3 years ago.
Impressions:
- Sure, the Sonys are louder (more sensitive) for a given input volume.
- However, when comparing Ohms, it's a logarithmic scale. That is, assuming all else equal, half the Ohms and the volume only increases around 3dBa, then need to halve it again to scrape together another 3dBa or so. So ignoring individual driver sensitivity for now, the difference between 24Ohms and 80Ohms is actually only around 5 to 7dBa, which is shit all.
- Compare 80 Ohm and 250 Ohm, again only 5dBa in volume difference, or a slight nudge of the volume scale.
- And unless one's at maximum on the volume pot, there's gonna be room to move to restore this missing 5dBa on a higher Ohm model, and the headphone amplifier (whether in-built on the soundcard, the iPhone, or dedicated headphone amplifier box) will be running less hard/heat/distortion, versus a low Ohm model (which like low Ohm loud speakers, is simply shorting the amplifier to force it to pump more juice into the drivers).
- As for sound comparisons between the Sony and Beyerdynamics, initially the sound was similar, the Sony's appearing to present a more 'upfront' sound... the Beyers a little laid back... then I began listening more critically and it became apparent that the Sonys were actually compressing the sound, quite significantly, like big maximising limiter. So while the Sony's appeared louder and in one's face, it was actually starving the music of dynamics. Whereas the Beyers may need to be turned up a little more to match apparent volume, the dynamics were extended, more real.
- For production or general listening for pleasure, the Beyer 990s is the absolute better choice, IMO.
- For DJing, well in a club environment, the 990s are simply not suited, being open-backed, the environmental noise is heard near identically whether the headphones are over the ears, or not. How about compared to the sealed backs of the 770s? Good question, and no idea. I'm tempted to get a set for monitoring in noisy environments and/or on stage. But for DJing, the Sonys (or whatever is the comparable product today), may have the edge as the limiting effect makes them LOUD (though perhaps annoying for extended listening, not unlike LOUD commercial breaks on the TV).
Of course, everyone else's mileage may vary.
