Just a few notes, the 6xx needs over 100+ hrs of burn in otherwise it'll be extremely lack luster. Otherwise, its great. The Sony's detail is lacking, definitely not something any audiophile could be satisfied with considering the 350 retail price tag. It's detail is actually a touch worse than my well burnt in Sen 558's, which i got for $80. The Noise canceling is amazing on it though. Just make sure if you get this drop, you understand that the Sony's should only be owned with a priority on noise cancellation. If blocking out strong noise is needed, then this is a good deal. I just moved from the Sony's to the Bose 700's because the bose offers similar noise cancellation quality but with sound an audiophile can be satisfied with. Need to burn the 700's in more, but so far they're falling inbetween my 1more quads and etymotic er4-xr's in terms of detail.
GuNStArHeRoI read the first line and my eyes rolled so hard to the back of my head lol but some speakers do need burn in and some bespoke headphones, nothing close to 100+ hours to the point of being "lackluster" lmao
Some grade A+ gatekeeping
KethMost high end audio manufacturers that have the resources burn-in their equipment. Please tell me more about how most high end manufacturers are wrong.
That being said, the 6xx(600,650) are notorious for needing a long burn to resemble anything decent. The sony's sounded the same on hour 1 vs hour 100. You don't have to believe me if you don't want to.
HispanicPanicSo why do you need to burn them in longer if the manufacturer already did it? Has anyone here ever bought a new TV that looked like shit until you burn it in for 100+ hrs? Or a car that shakes and rattles until you burn it in for a month? Why would a major manufacturer sell you anything that's below their quality standards? how could Sennheiser tell this headphone sounds like it's supposed to if you need to run it for an extra 100 hrs before it reaches the target sound signature? 🤔🤨🧐
HispanicPanicYou must be the biggest fool if you believe in the hardware burn in of headphones. You probably also believe in $2000 cables. The only burn in is the customer who adapts to the sound signature of the headphones over time. I certainly don't notice any sonic difference in my 6XX after 1 month. If you need any further convincing, here is a link to a very informative video: https://www.youtube.com/watch?v=AeyVvORvvIw
Sonic signatures vary greatly, and the lack of sound stage of the 600 series takes a lot of adjusting to if you're coming from something wide. You're burning in, not the headphones.
To make people keep them past the return window.
They're buying their own BS. Audioquest recommends over 200 hours of burn in on the Nighthawk and Nightowl, I've heard no meaningful difference on my Nighthawks after 300 hours. Which goes back to point one, they're a very unique sounding headphone that takes a lot of adjustment to get used to.
The idea of burn in is that the driver somehow changes over time, Sennheiser themselves call BS on this, by stating that their headphones are good to go out of the box, and it's you adjusting to them. The Mylar drivers in the 600 series aren't constructed with a material that has the potential for change over time. Bio Dynamic drivers may have some potential for change over time, but measurements don't support that they do. And Planar magnetic drivers are kept at a specific tension, and don't change over time.
HispanicPanicThat's interesting to hear. I'm leaning towards the 700's myself and have had the M3's. Not great detail and too much bass although at least they have an equalizer for the bass. The 700's are slightly more comfy on my ears too although not sure about that headband. I guess I can always try them and return the if they don't work out.
KethI only know of one thing I could call "burn-in" and that relates to vacuum tubes. Everything else breaks-in and usually takes less than 10hrs to do so.
100+ hrs of use is beyond the return period for most users and is IMO the primary reason a manufacturer quotes stuff like that. Own three planars and have noticed zero change, probably a 1000 hrs deep on my HE500. Two Bio's that took a little longer but still a fraction of 100 hrs. The Senn pads are very stiff new and deflate a ton over time, this puts the drivers closer to peoples ears and is what i generally attribute to the this "needs burn-in" statements.
Not a big ascriber to "brain burn-in" either but with 33 pairs in varying styles and sound sigs I am probably in the minority in my habits. DT990 sits for weeks/months at a time but still sounds like I "remember" it as soons as I fire up some tunes. My opinion on its sound hasn't changed despite 29 pairs coming after it.
ElectronicVicesI wasn't big on brain burn in either, until the Nighthawks. If i wear them for a week+ I adjust to them and they sound amazing. But the second I put on my LCD2-F's I realize how dysfunctional the Nighthawks sound signature is.
HispanicPanicI agree the Sony is more about it’s powerful ANC, but the great thing about this bundle is you get two “extremes” of the ANC vs HiFi spectrum, and both are some of the best values in their respective categories.
@Keth The Audioquest Nightmares were not a good fit for my tastes, but I only listened to them on two separate occasions instead of forcing myself to acclimate. It’s the kind of sound signature that is really fun with some genres/tracks, but too far off neutral for others. Still, I give Audioquest credit for intentionally designing a specific flavor.
EvshrugI have my T60RP Argon's now, they check all my boxes...though they're a splurge, no advantage over the T50 model ($100 cheaper) other than looks.
Scio_Me_ScireIt's been 9 months since I've listened to the T60, but what I can say for sure is that the bass extends lower, and it has way more slam. It's much wider, eliminates the treble peaks, and the larger pads lessens the creaky nature of T60.
The Argons also change the baffles to 90% closed, to they isolate better as well.
