If you are looking for accurate sound for critical listening and require the isolation closed-back headphones offer, these are worth checking out. I was impressed with the M1's combination of transient and frequency response accuracy, combined with imaging and soundstage that outperforms many open-back designs I work with regularly. At a suggested price of $249.99 usd, there is compelling value imo... Thanks again to SONY for providing these so I could work with them in advance of release.
I always come directly here to find out the real info. I have been using my AKG 361s since your recommendation way back when and have had great use out of them. The pads are starting to go on mine and the cable is getting a bit tired so would be interested in picking up a new pair of reference phones. Would be very curious to see how these stack up next to some of your previously reviewed cans like the AKGs.
I've been working with the 7506, cd900st, z1 for quite sometime. This review is so helpful and I intend to get one due to this review. Thanks Todd! Subscribing right away!
Was I the only one who heard a weird buzz coming through the right channel during the spoken word example of the headphones? (6:51-6:58) I listened with both my Beyerdynamic DT-770 and DT-990 Pros, and it was there.
I was going to import a pair of MDR-CD900ST and SONY just release this, thank you very much for the review I think maybe is better to wait to get one M1 in my country.
Another great review, and I wholeheartedly agree with your approach to reviewing headphones. It puts the consumer in a place to make their own decision upon listening. My own experience closely matches what I hear on your demos, despite some concerns expressed about your review technique. As far as these new Sony headphones though, to my ears they have excessive bass (around 80hz) and too much sizzle in the highs (around 6-7kHz). Thx JB
I was so close to pulling trigger on the neumann closed backs. I really need good, accurate sub bass monitoring. If these can deliver that for £200 then holy shit, take my money.
Got them all 😂. 7506/900st/mv1, and many others, just a headphone freak, but not consumer ones (too boom bassy). Will order them blind, just like Victor 100z if they are fully manufactured in Japan.
That is an AMAZING performance, especially for that low price! Damn, now I need to buy them. I hope for a more clean reproduction than my Beyer Dynamic DT-770 PRO's deliver. If they can do that, the Sony's will be my new mains for headphone monitoring. Thanks for this detailed and great review!
I don’t understand why it is recommended. The deviation from the original souund is huge. Even the k240s is more neutral. Am I missing something? Is the recording rig not representative of the real life sound va the original?
Value is good with these, I believe they will be very useful for anyone trying to make good mix / production decisions in a less than ideal space... Cheers!
Todd, It feels like these headphones have a peak around 11 KHZ, but you never acknowledged the existence of such a peak. Interestingly, it's a similar rise as on your narration for this video. Will I be hearing this if I buy a pair?
@@666dreamboat damn, thank you. That kind of sucks! I really do wonder how audible it actually is, but we’ll see. Reason I didn’t catch it was because I’m totally blind, so thank you for filling in the gap.
@@NickG6489 no problem, thanks for not being annoyed at me. At 250 you have to compete with the hd6xx which may have a sound you are already used to and the beyerdynamic offerings and honestly if don't haven't completely dropped the ball this will probably best them as a reference. I'm interested to see what the open back sounds like personally!
@@666dreamboat I have DT700ProX and DT9000ProX. Sound different from each other that i really can't use them as a common platform, which was my hope. I'm probably going to try these to see if they are better than the 700ProX, we'll see if my ears break in and get used to that 12 K peak. ...THey got used to the issues in the 700ProX...
@@NickG6489 honestly think if you are cursed with terrible ears like me something harman, something v shaped and something flat helps a bunch. Most of the time I use audeze lcdx, yamaha hs8 speaker check, and akg k371 for sanity. By far the most useful is the audeze with reveal running on my control room.
I seriously don't get why a flat response is deemed reference when it's only accurate in a measured form but inaccurate in a perceived form. To have and more importantly hear the latter in equal loudness form (perceived flat) then a bass-orientated curve needs to be applied. I have the ATH-M50xBT2 which measure just as flat / non-"coloured" as these Sony's but they lack equal loudness and I've spent a year dialing in EQ settings (using my DAW with Pro-Q3 and a custom made pink noise filtered calibration test) and now they sound great and I've even say perfect. Maybe these Sony's are (alike the AT's) great for reference as the starting point, but that's just not the end goal (in my opinion).
The idea, at least, is if you hear your bass guitar playing in the headphone, it's going to sound as realistic to your bass guitar sound in the room, and not some other treatment of music for listening pleasure. Trying to hear your performance and make choices in settings, hand use, etc can all be impacted by a sound that might not be so accurate to what the mic is picking up.
@@alexbreyer6921Thanks for your input, but the way I see (or hear) it is that a measured flat response at typical household dB (70-80dB) sounds lacking in the bass area and the noise sounds like it's coming from a speaker (aka unnatural) that's trying to replicate reality but slightly failing instead due to not compensating the reduced perceived frequency receivership within our ears. The vast majority of recognised studies (Fletcher Munson, dBA, dBB, Dolby Reference dBC, ISO226, Harman etc) state that a curve (relative to listening volume) is required to make the perceived sound to match reality. It's not treating anything, it's just making it accurate. A flat response would only be applicable in extreme volume requirements - basically a loud-as-hell concert. Cinematic/ Dolby standard with peak reference output of 105dB has a +6dB boost on LFE channel (although it's around 9dB @ 40Hz in total after factoring dBC weighting). Typical household music listening is around 70dB which using dBB (I think is the best calibration for that volume) has a boost of around 14dB @ 40Hz. Most of these curves become flat in the mid-range or lower (Dolby boosts slightly around 1k but LFE starts to sound at 120Hz but doesn't hit its peak until 80Hz and lower. My AT headphones have a similar curve to dBB applied (my EQ) but with a slightly reduced curve as I go up to around 80dB so I target around 10dB @ 40Hz. Sounds not only pleasurable, but accurate / realistic. If you calibrate to a bass-boosted standard like dBB then bypass the EQ to run flat, then flat will sound absolutely terrible. Completely night & day difference. One day most people will hopefully realise that a flat response is generally flawed and non-applicable for mainstream use.
@LargeStyle hey, I also have the AT m50xbt2, and I was wondering if have any problems getting enough volume out of them in BT mode on certain things??
@@gizzy2403 No volume issues for me. I listen to music around 70% and movies nearer 90% and that's plenty loud enough for me. This applies to when connected via BT to PC, TV or phone (I don't normally run wired). Just double check your sources output levels maybe? If it's massively quiet & tinny sounding then disable side-tone in the mobile app, and on PC disable hands-free in device settings.
Well I mean this test isn’t exactly a good representation… I think it’s novel and all but yeah… listening to a recording of headphones on different headphones kinda defeats the purpose in the end.
@@JobbyFraggle Yes, it's not possible to actually hear headphones or monitors over others, but the idea I'm trying to share with recorded audio is to listen for the difference between the original and the headphone recording to get an idea of what coloration may be introduced. I haven't been able to come up with a better way to review headphones without falling into the usual collection of descriptions that mean different things to everyone... Only way to hear the actual sound (which is different for everyone due to the physics of our ears) to to listen in-person...worth it in this case imo... Cheers!
Sony once again disappoints. Sennheiser HD620s is more faithful and has angled drivers for better imaging. Out of all the headphones you have tested, the HD 400 Pro is the most accurate (to the human ear) at Studio Reference Level. If you listen at ear damaging levels the HD 400 Pro will sound a bit harsh in the frequencies the human ear is most sensitive to (Equal Loudness Contour). I can rely on the HD400 Pro to tell me what exactly is going on. They are so accurate that they can be used for binaural reproduction. They are pretty much transparent.
lol Sennheiser lately releases disaster after disaster, HD660S2 is a disaster with muffled mids, HD400 sound cold and distant and it has very very low resolution, HD620s is a disaster just listen to sound tests on youtube it's base sounds like wet poop, while recently released Sony MDR-MV1 are absolutely phenomenal..........dude
@@michaelsi6770agree, hd600/650 are still much better, but mv1 are really good. Similar to 900st but more detailed. I am currently waiting for the new Fostex t50rp mk.4 and Victor 100z (His Master's Voice). As a collector and audiophile I prefer studio detailed approach rather than consumer one, not even mentioning Bluetooth (except for Grados, with modded detachable cables).
I am not sure how to read your comment. Did you actually listen to the HD620 and the Sony or are you basing this on specs? There are a lot better headphones out there which don't have angled drivers. It's really not a make or break thing. It's a design feature for specifiek dynamic driver designs.
