Man of Honour
Yup, hence posting the link here
The only obvious difference is the 650 is 300ohm, the 660S is 150ohm. The 660s would therefore be easier to drive louder with lower powered sources, so maybe this is where the claims of better sub-bass comes from?
The 6XX is just Massdrop's custom coloured HD650, no other difference
So these are not no Chinese rubbish then lolI was replying to the post above me from Nicknack - he asked what 6XX meant
Any difference to these then the HD650's??? I know the Cans look the same but these are 6XX
No it doesn't matter so much about listening while the wife is sleeping now. The 400i do get great reviews but i think they would be uncomfy i like the design of the HD650 I think they would be a better all rounderThe HD650 has a mid bass "hump", so there is bass emphasis and is why it sounds bassier than the HD600. What it doesn't have is any sub-bass as it rolls off sharply from 50~60Hz, which is one of the differences between it and the HE400i, which carries on down to 20Hz or so, something that planars excel at.
The Hd650 has some of the best mids you'll find outside of TOTL offerings from the £1k+ sector. The HE400i isn't far behind though, it too has excellent mids, they are just not as lush and rich as the Sennheisers.
The high frequencies pose something of a split in opinions, there is plenty of detail there, it's just that they are rolled off compared with the mids, which is where the (erroneous) veil description comes from. If you are used to listening to headphones that have hot highs, like the AKG K702 or Beyerdynamic DT 770, 880 or 990 (or Teslas) then yes, the HD650 will sound somewhat dull and muffled to start with BUT after listening for an hour or two, this "veil" will lift and you'll discover all that detail was there all the time. The HE400i on the other hand has much airier and more detailed highs which provide very accurate imaging, which is somewhere the the HD650s fall down, they tend to have focal "blobs" and instruments / voices will be central, left or right while the HE400i (and specially the HE560i) have imaging that lets you visualise the exact positions of the instruments.
One word of caution, you mention that you want to use them in bed, while your wife is sleeping - wouldn't closed back headphones be better? The HD650 isolates poorly, being open backed and the HE400i is more like a pair of speakers strapped to your head and can be heard easily from 15 plus feet away.
No idea where the 6XX are made but the HD650 and HD660 are made in Ireland - so it's more than likely the 6XX are too
It's not more than likely, they are made in Ireland
Manufacturing plants
- Germany (microphones, headphones, wireless microphone and monitoring systems, conference and information systems)
- Ireland (headphones, audiology products, monitor loudspeakers, integrated systems products)
- USA (wireless microphone and monitoring systems)
Trying to find where I read it but failing. Definitely was something about 2 county of origin. Unless I dreamed it...According to that (from their website), headphones are only manufactured in Germany and Ireland and nothing gets made in the far east
Someone in the Massdrop discussion page said the HD6XX will also be made in Ireland like the HD650. I can't find that description anywhere. Can anyone verify?
[Jude] Yes, it is being manufactured in the same factory in Tullamore, Ireland.
