Raw frequency response plots of the wired passive mode show respons between 400Hz and 2kHz somewhat above target response giving this headphone an emphasized and forward upper half of the midrange. Bass response is fairly on-target and punchy sounding, but is a bit overwhelmed by the midrange emphasis. Treble between 4-8kHz is significantly suppressed; I would like it to be about 5dB higher in this region.

30Hz square wave is nicely shaped showing good impact and bass extension. But the initial transient is too high, which tends to overwhelm the good bass response.

300Hz square wave is a little slow to rise and a little too high. This evidences the lack of mid-treble and overemphatic upper-midrange.

Distortion is a bit high in passive mode, but you can see distortion is lozer in active modes. I think this is mostly due to the noise canceling reducing the noise component of the THD+noise measurement. These headphones do sound a bit hard to me, which is usually the sound of distortion making itself known. I hear it less in noise canceling modes—maybe the DSP is putting in some fixes—but it's still there.

Raw frequency response plots of the active wired mode show a significant difference in level between the two channels. I think this should be largely ignored. I had the chance to measure these headphones a number of times and the matching would change each time a bit. The right channel did seem to reliable have less bass extension. I think there's a combination of factors here: The pads didn't really like to seal on my head very well, and the matching would change when I did the TruNote calibration...depending on the seal possibly. At any rate, I think there might be a missmatch, but I don't think it's quite as big as shown.

Frequency response profile is quite good and fairly even to 2kHz. Worthy of note is a loss of bass extension, probably due to low frequency limiting of the DSP or capacitive coupling in the headphone electronics. Bass did sound a bit looser but was better balanced with the midrange in active mode.

Also worth noting is the slightly broader than normal peak at 3kHz. I'm guessing they did something to widen the peak so that it always fell within the natural concha bowl peak of the listeners ear...or something like that. The dip between 4-8kHz remains, and does reduce nuanced treble, however, it is a bit more emphasized here than in passive wired mode, and the treble did seem a bit more natural here as a result.

30Hz square waves now show a significantly more curve wave form top, related to the lack of extension as shown on raw FR plots. You can also now note some pre-ringing likely due to high-frequency phase shifting in DSP. This doesn't seem as audible as it looks in the plots.

In the 300Hz square wave the pre-ringing is now quite obvious and make a complete mess of the waveshape. Again, I don't think it sounds as bad as it looks.

There is no impulse response plot because the DSP messes with the MLSS waveform too much for the AP tester to synchronize.

THD+noise plots show modest levels, but it is important to note the noise canceling might make this measurement better than it appears.

Impedance plots show the input impedance of the electrical circuits and show a nominal (as expected) response.

Isolation is quite good at -28dB broadband. Equaling the Bose QC35 broadband measurement, but is not quite as good at low frequencies.

I've seen this at Best Buy, always wondered about it. I know some others who really like it.

A wry smiley face eq for the HD650 and a slightly bigger one for the Momentum 2.0 has worked well for me

Wry wasn't the right word, a small smiley face eq puts the HD650 right in my wheelhouse and a bigger smiley face eq for the M2 tames the forwardness without losing much fidelity, none that I can tell.

Have you listened to the Sony MDR-1000x? I'm really impressed with that headphone and am wondering how this would compare and if it would be an upgrade.

Have been using the MDR 1000X for a couple of months now and I take couple of flights every week, and boy do they do a good job. Sony also got the tonality right, no bass bloats or harsh highs, just the right balance.

For convenience alone 1000x has now replaced all my portable HPs and also stands between me and a bunch of UIEM/CIEM just because of the isolation it can provide outside. I am not a Sony fanboy and currently I own only one other Sony masterpiece from the 90s the MDR CD 3000. 1000X is here to stay and I think it will be benchmark for all ANC HP manufacturers in the foreseeable future.

They're on the way.

Hey Tyll, wondering if you have an update on when your review of the Sony MDR 1000x will be completed and posted. Looking forward to seeing your evaluation of them--especially as compared to the Bose QC35, the Sennheiser Momentum Wireless, and the JBL Everest 700 Elite.

Mark my words! : )

And i think that sonically it is the more convenient

Thanks Tyll for this write up. Ive found JBL to be a bit of a hit/miss producer when it comes to sound quality but i TOTALLY dig that you are checking their stuff out and posting when you like it as they are part of the group of brands commonly found at brick and mortar stores (also Sony, Skullcandy, Bose, etc). If there are some gems within these brands its good to know in case I ever come across a good deal/opportunity.

Peace .n. Living in Stereo

The whole "tuned to your ears" made me think about snake oil... I liked your test for clamping to thigh and then to head. Do test head makers provide alternative ears for testing?

I'm still waiting for a noise cancelling headphone that I actually like, instead of just saying "yeah, that'll do for the next 11 hours." I still have a set of Sony noise cancelling headphones I bought back in the 90s. I've tried many alternatives since then and all of them have a weird pressure wave feeling, and a plastic-y or some other term for synthesized reality sound. My continuing disappointment with noise cancelling years ago led me to CIEMs.

I wonder if we're finally getting to where the computational power for great noise cancelling is feasible.

I wonder how these would stack up to Sennheiser's recently released HD 4.50BTNC and HD 4.40BT models at CES 2017. The Senns not provide any calibration, but are priced attractively. From the initial limited reviews at the stall, the latter sound good value for money.

Tyll, would be great to hear your view on these Senns.

I was really disappointed by the Sennheiser HD 4.50 BTNC even though I got them for 149 €. With ANC enabled they sound really band and even without ANC it sounded as if a lot was missing (novice speaking). I just compared them to the JBL Everest Elite 700 in a local store and the JBL sound much better.
