Sennheiser HD660S Speculation

But this assumes that anyone would ever use it on the street, which they won't, because it's open.

Maybe mobile-friendly is so one can use it around the house. In which case, sure, I'd hate for my wife not to know that I'm using Sennheisers!

But wait... she'd have to be standing on the side where it can be read...

 

Because he didn't have time to make them. You see, he is a very busy man and had a flight to catch, but still managed to get a preliminary measurement for the plebs to endlessly dissect and fawn over. You should be glad we even got that much.

 

Marketing open headphones as mobile friendly is stupid. Frequent Travellers with any sense and concern for their hearing will use noise cancelling cans. Nobody is going to take the 660s AND their QC35s on a trip. Again nobody spends £430 on fully open cans to use with their mobile phone.

Sennheiser if you've done a small incremental update after 14 years I'm going to be pissed.

 

The only thing that comes to mind is Sennheiser X Leica: HD660S Doctor/Lawyer edition.

 

There are a few reviews on the US Sennheiser site page now. Looks like there might be some trolling going on, just a hunch though.

 

Besides improving the subbass and air, what else can they do with a HD650 that wouldn't ruin what made it so appealing to a lot of people? Maybe a soundstage and resolve improvement, but messing with the FR too much would ruin the tonality people wanted from it in the first place.

 

Meh, I'm just glad they seem to be making an attempt at updating the HD650 instead of contributing to the high priced dick waving other manufacturers have been (also glad to see some of those same manufacturers redirecting effort to the sub $1000 market). Until I see reviews from people I trust or I'm given a chance to hear them for myself, I'm going to give Sennheiser the benefit of a doubt and hope they've managed to succeed in building upon the HD6xx legacy.

 

Many pages back, I laid out what I thought was a sensible explanation for why Sennheiser as a brand and a business would want to roll out a lower impedance version of the same sound as the HD650. Turns out this is the case.

The small differences in FR between the HD650 and the HD660 S on Jude's measurement could very well be due to the limitations of tuning one driver to sound like another, and the age of the pads.

EDIT: And since I've yet to see Jude not act as a marketer on behalf of every headphone he's reviewed, I simply don't trust his subjective comments on resolution and such.

 

I'd like to see that too, and if I were Sennheiser, that'd be the HD1000 and definitely not an HD660 S that shares the price point of an HD 650.

 

I thought it was a rule of thumb to match frequency responses at 1kz when comparing. Is it not?

 

It varies depending on what makes the headphones look better.

Jokes aside, not sure why he matched it at 3Khz. That was kind of odd.

 

Kind of a dumb thought, but that "ideal" 660 line looks a lot like an Eikon with the upper-mids brought up. Or an Elear if the french didn't wave the white flag once they got to the treble.

 

Matching at just one frequency plot can be troublesome, because headphones can have such erratic dips and peaks that might coincide with said frequency. I would average it out, like this:




Based on how close the two align, it could just be the exact same tuning, with the differences being in pads etc. The actual differences are probably elsewhere which measurements won't show as easily.

Yes, Jude's graphs have a null just before 10k, but we all know how Jude's measurements handle 10k area based on the Z1R ordeal with Tyll. Getting consistent measurements past 6k and especially 10k is hard anyways.

 

Yeah, he really ratcheted up the tension with that 'desperate to make a flight, but dammit I'm ultimately here to serve you!' story. Will he? Won't he? Agonizingly edge-of-your-seat, I was sweating buckets up to the thrilling conclusion (don't worry, no spoilers!).

 

I really like this
So basically, nothing much different. If the distorsion and waterfall plots, and square responses are so simmilar, the only real difference should be an impedance cut making them a bit easier on the devices with lower voltage max output. And yes, mr wayne, it comes in all black.

 

I agree to some extent. It also reminds me of worn pads on an HD650. More mid focus and roll off on either end. I'll wait for @Marvey measurements but I'm guessing this is simply meant to be an easier to drive HD650 with less mid bass.
