    Why the Beats Hate?

    It depends on what your target/reference for a headphone frequency response is, but based on our target (which is quite similar to the Harman target), not only the Grados have too much treble and not enough bass, but all headphones in the Srxxxe series measure basically the same.

    Headphone Soundstage and Imaging: Definitions & Measurements

    hehe, thanks! Yes, a good and accurate frequency response (especially treble response) is essential for good imaging, and a headphone with a poor or lacking treble will have a poor imaging. However, if such a headphone has very good L/R driver matching, it would still score well in our imaging...

    Headphone Soundstage and Imaging: Definitions & Measurements

    Hi all, So like last year, we've made a video explaining the philosophy and testing methodology behind a couple of our tests, and this one is about soundstage and imaging. Let me know if you have any comments or suggestions. Sam

    Open-Back Headphones (Driving Issue)

    How about Sennheiser Game One? Its impedance is 50ohm, should be no problem to drive. HD599/598 would also be good alternatives, but they don't have a mic.

    Help understanding 800S Frequency

    I am curious if you have suggestions on how to improve our compensation curve? Do you find issues with it throughout the range, or just in the treble? Personally, I agree with you that our compensation curve is not quite there yet, but only in the treble range, and that's partially due to the...

    Sennheiser HD 598 CS Closed Back

    I just listened to the M50, DT770 and 598Cs, and in terms of sound quality would rank them in that order. So I would say the M50x has best sound of the three. The DT770 is bit too sizzly in the treble, but it's the most comfortable and can be fixed by cutting the 7KHz-10KHz region just by a few...

    Most open/wide/large soundstage headphone?

    I have measured/listened to the Edition X, and based on our measurements, it does better than 800 S in a couple of area. But the 800 S seems to provide some elevation cues as well (giving the sense of sounds coming from front and slightly above, rather than just in front), which could be the...

    Most open/wide/large soundstage headphone?

    HD 800 S would be hard to beat in terms of soundstage that is not created with the aid of DSP. We have just updated the soundstage test and ranking on our website, and although not perfect, should be a decent guide for evaluating soundstage.

    IEM Cleaning Mesh, muffled sound???

    I've had similar negative experiences with 75% isopropyl alcohol. I'd suggest using 99% alcohol (the problem seems to be the water content), and then giving the headphones enough time to dry. I also, don't let them soak for too long as you can dissolve the glue and loosening the diaphragm.

    Mad Lust Envy's Headphone Gaming Guide: (2/2/2020: Drop + THX Panda review added)

    We agree with you that our headphone reviews aren't as mature as our TV reviews yet, since we started reviewing headphones more recently. But we are as serious about them and are constantly thinking of ways to improve our reviews. We will be posting a "best gaming headphones" article soon with...

    Mad Lust Envy's Headphone Gaming Guide: (2/2/2020: Drop + THX Panda review added)

    It seems that by binaural capabalities you are referring to what we call "imaging" in our reviews. We score Imaging based on phase response and driver matching. However, we believe there's room for improvement in our Imaging calculations and we should go live with the update within a month or...

    Rtings.com - Real vs Fake Headphones: 5 Models Compared - Beats, Bose & Apple

    Personally, that was my biggest surprise, that how difficult it is to tell the fakes from originals, even if they are sitting next to each other. But after a bit of touching and listening, it becomes quite clear. Part of me wish they would spend more energy on faking the sound quality and not...

    Headphones Frequency Response: Challenges & Solutions

    Our frequency response plots are already compensated, so our dotted target line is the flattened version of our compensation curve.

    Headphones Frequency Response: Challenges & Solutions

    Depending on the quality of the earpads, and glasses/hairstyle, there could be a lot more than a couple of dBs of variance: http://www.rtings.com/headphones/reviews/sennheiser/rs-195#comparison_568 Correction softwares should come with their own microphones for calibration, otherwise there...

    Headphones Frequency Response: Challenges & Solutions

    We have thought about doing something like that, but providing a corrective EQ based on measurements done on other people will be an approximation at best. It only works without issues if the measurements were done on you, using your headphones.

    Headphones Frequency Response: Challenges & Solutions

    - Headphones don't have crosstalk, so for them to create a proper Soundstage, they need to artificiality add some correlated crosstalk. - Headphones don't interact with human's HRTF like loudspeakers do. To tackle this, you either need very large and deep drivers like the HD 800 S (which only...

    Headphones Frequency Response: Challenges & Solutions

    You're not blind to Soundstage, it's just the none of the currently available headphones do all those 4 things that we test for right! But if they do it right (like what the Smyth Realiser tries to do), then except for the visceral bass effect, there shouldn't be much of a difference between...

    Headphones Frequency Response: Challenges & Solutions

    Exactly, that's why the Treble of the Harman curve didn't quite work for us and we used the Diffuse Field measurement of our HMS instead. I also did try making an in-room curve with our HMS in two different rooms, but for some reason I still preferred the sound of the diffuse field. Sean Olive...

    Headphones Frequency Response: Challenges & Solutions

    Thanks for all the comments guys! :) The idea comes from the assumption that the perfect headphone sounds like the perfect loudspeaker in the perfect room, whatever perfect means*. And this was largely confirmed in a few studies where listener's preference was measured. *Harman took Floyd...

    Headphones Frequency Response: Challenges & Solutions

    Agreed. That's what we're trying to do with our scoring algorithm. It has less weight in low-bass and high-treble regions, and we have even more plans to make the scoring system more perceptually relevant in the near future.

    Headphones Frequency Response: Challenges & Solutions

    That of course is a possibility, but a highly unlikely one for a couple of a reasons. Harman sent me measurements of 6 different headphones to compare and not just the HD 600, and you see a relatively similar offset in all of them. Additionally, you can compare the measurement of our HD 600 to...

    Headphones Frequency Response: Challenges & Solutions

    As I say in the video, one of the reasons the Harman curve didn't work for us, was that it was based on measurements on a different head. Attached is the frequency response of the HD 600 (albeit not the same unit) on our rig (Green) vs the Harman's rig (Red), and as you can see there's no way...

    Headphones Frequency Response: Challenges & Solutions

    Well, I'm trying not to get in the middle of that discussion at the moment :) and this video wasn't meant as a response to that. But yes, hopefully it will provide some perspective on the state of currently available measurements. Thanks for your comment. Providing raw responses of our...
