I’ve done math like this in the past when I was using a Q701 and HD650 and was proving the same point about not really needing tons of power. These numbers for the Timeless still aren’t making sense to me though.Most people don't realize that it doesn't take as much power to push head gear as is professed by some. For instance, for some 300ohm headphones with a 102dB/mW sensitivity, you really only need (to reach a whopping 110dBSPL):
Now, this doesn't account for the voltage swing that you would get (at differing frequencies) and remember with planars the voltage doesn't swing up or down, it the is the current that swings (the opposite of DD, where current draw is steady). Also, keep in mind that this only means that you can drive them to that dB level. It doesn't mean they will sound good or bad. These are calculations on paper, and IRL they might be slightly different.
- 7mW
- 1.45VRMS
- 4.8mA
Anyway, I’ve figured out the fit with these and they are comfortable now. Now I just need a pair that doesn’t have an issue on the right side. The comfort issue was me trying to shove them too deep into my ear holes. As of right now I have no issues with comfort with the tips that come installed in the box. So yay.
