    There have been 2-3 price hikes in the last couple of years. B&K blames covid.

    aah! Thanks for the clarification! :facepalm:

    Speed Reading DAC Audio Measurements

    Thanks for the video Amir. Quite informative. :) Quick observation: I noticed that the balanced input for the CD players RMS level test is at 2.5 Vrms. Shouldn't it be 5 Vrms, or am I missing something? Could that explain the low RMS level of the CD player? Sam

    AKG K701 Headphone Reviews (China and Austrian Made)

    My experience is that K701, K702, K712, and Q701, are pretty much the same headphone.

    LTT Lab is going Brüel & Kjær

    We wanted to use Harman's method (attaching a MEMS mic to the Sennheiser Momentum in-ear) but soldering the MEMS is not that easy.

    LTT Lab is going Brüel & Kjær

    Can't tell if you're joking or not :-) I was talking more about their calculations. For example, not including the full audio spectrum (20Hz - 20kHz) allows for some headphones with a bad response at the extremes of hearing range to slip through. Also, quite often, I found the slope calculation...

    LTT Lab is going Brüel & Kjær

    Last time I asked, B&K wasn't going make different ears in the near future. Maybe we can make them ourselves, but that's not the highest priority for now.

    LTT Lab is going Brüel & Kjær

    This is fair. What I did at RTINGS was more on the experimental side (and we were open about it), but here the plan is to be more legitimate from the start. We will still experiment, since we what to improve what's already out there, but only when we can confidently defend our work. I don't...

    LTT Lab is going Brüel & Kjær

    We haven't been able to find a way out of the measurement variance issue yet. It seems unless one does personalized measurements, headphone measurement results are always going to represent the average human, not any individual. We are also not concerned with our measurements not matching...

    LTT Lab is going Brüel & Kjær

    I don't think there's a way to get around the issue of variability in measurements, especially since the variabilities happen on humans too and can be non-linear. I agree with you on the IEM seal issue, but that problem exists on the 711-based fixtures too, although to a lesser extent. We did...

    That's the plan. As mentioned in the notes, this was just a taster, we're working on improving the methodology.

    LTT Lab is going Brüel & Kjær

    Finding a reliable way to do this objectively is on our agenda, but it may not be that easy. It's also not the highest priority test for the beginning.

    LTT Lab is going Brüel & Kjær

    We wanted to measure the bass of IEMs on humans as well, and even got the equipment for it. But we couldn't get around building the rig during the rental period. We might still do it in the future.

    AKG K701 Headphone Reviews (China and Austrian Made)

    Cool, most of those are already on my list. I don't think it's going to be video-only.

    AKG K701 Headphone Reviews (China and Austrian Made)

    We got an extra rubber ear and chopped its pinna off. It was identical to the regular one we used except that it didn't have the outer ear. The 10kHz dip was one of the calculations we did. Another one was the amount of pinna effect (boost). I believe the 10kHz is the result of a cancelation...
