That's exactly the kind of thing I'd like to fill my life with for the next 20 years.
Deadly serious.

FWIW the old IEC headphone measurement spec required using a 120 Ohm output impedance amp. The spec is now changed and says that manufacturers can specify a particular output impedance at which to measure the cans. Beyer was a proponant of the 120 Ohm spec and I wouldn't be surprised if they are still designing their headphones around it.
Personally I think it's stupid for high-end cans to be designed with a 120 Ohm output in mind.

I demand an offically recognised birthday date.
tkam's join date was 2-21
Blow out the candles and let's open a bottle.

Cool, thanks Graham. I can tell you it's annoying to no end to have people say, "Measurements don't mean anything."
-
At least not that I found easily and intuitively by clicking Home or some such. There should be an obvious link at the top of the page in case anybody from HR is reading here.
Sigh.
Oh well ... I will work for this hobby again one day.

Oh great, you wish a guy happy birthday and he shows you all the good grog he got to drink.
Oh well, happy birthday anyway Stephan.

No, it was meant as a recommendation, but I realize in hindsight it wouldn't be very helpful. It lets you listen to music you may not have heard before, but sounds like something you have heard before.
Actually, I've listened to Pandora quite a bit too. And yes, it does a good job of playing music similar to something you seed it with. Sometime when I want background music that won't distract I'll poke something like Pat Metheny into Pandora and just let it stream.

There are two legs on a pair of pants and two cups on a pair of headphones.
Well... I don't call it my nutsacks.

I don't notice the handful of FLAC's amongst all my MP3s. Oh, the horror.
Manfession: My most commonly listened to source is streaming radio off the interweb with an average bitrate of about 96kbs.
What can I say, I want to listen to music I haven't heard before.

I would say they do sound brighter than the 650, in there with the 701 but in a different way.

Been doing quite a bit of listening with these over the last day or two. Frankly, I'm amazed it does as well as id does in a pretty crouded field of damn good headphones. The mids seem really soulful to me, lots of body and strength. But I do hear something odd going on in the higs. I haven't measured them yet, but the guy in Japan seems to produce quality data and I tend to hear some stuff missing and some stuff accentuated as the graphs would imply. Cymbals are a little splashy sounding but the overal effect is omehow laid back at the same time.
I'm not sure that the mixed results you're seeing is due to manufacturing variance as much as it is just some unevenness in response.
I would suggest they may be similer to Grados in that regard.
I also think he needs to work on the earpad some; it seems to contact my head top and bottom and not fore and aft as much.
One the whole though, I'm amazed at how good they sound. A real luscious old school sound; I'm enjoying them.

I have to say I could quite happily live with the RS170 (closed) or RS180 (open) for quite some time. I really do think they sounded great for what they are. My guess is that for folks here using a wireless as a secondary headphone for music while doing dishes or for movies or listening in bed, they would be quite satisfied.
The RS160 is pretty range limited; good for a bedroom headphone though.
-
Here, lemme help ya: I really thought the 380 sucked too.
You're welcome.
-
I say again, how do you not notice this?
-
Man, you wonder what the strategy will be to deliver a come-back.
Thin out, for sure.
Discontinue the low money makers.
R&D is expensive.
Focus on the products with good sell through.
Focus on developing stronger partnerships with .. say ... Radio Shack.
I sorta don't see them with a gas pedal to step on, the headphone market is furiously competitive and busting with new product from every direction. Be pretty tough selling "The Plug" when so many better products are appearing out there.
I dunno. I'm guessing they'll either have to thin down to a shadow of their former self, or try to sell the brand to someone who's got the money and will to refresh it.
They do have very good brand recognition, someone is bound to see that as an opportunity. Logitec? Sumpin' like that.
edit - Does bankruptcy let them off the hook from previous warranty commitments?

Reviewed those wireless cans on my blog a coupla weeks ago, Al. They're pretty friggen amazingly good.
-
Tyll! How you doin? You at CES or know what they are announcing?
Nah. I'm not going to CES and have no idea what they're announcing.
I tell you what though, they've been putting out some great shit lately (PX100-II, CX 300-II, the new wireless stuff), I'd guess it's the logo thing, but if there's product coming along too, I bet it's pretty damn good.

not so shocking that I am the only one that prefers the HD800 to the HE90 (ducks, but thinks it is too soft in presentation)
No, I'm with you John, the euphony tends to stick to your taint and makes you squirm after a while. The HD800 will scrape that clean off.
I do think the HD800 has a bit of dry glare or sumpin', but balancing them and recabling does wonders to deliver just plain clean sound.

Tyll,
Any way to get the intermediate frequency lines to show up lighter? Kind of hard to read that graph for me otherwise and your old graphs used to do a lovely job of this.
The graphing software is a bitch, not sure what they're going to look like when they go up for real. But I note and agree with your comment.

I'll do some looking into our impedance measurement.
We do do it with the cans on the dummy, and it does change the impedance curve a little. But usually just a little, no where near the the difference between our data and Stereophile's.
I'll let you guys know in a week or two.

Ho ho ho! Off to the airport destined for ATL.
See you tomorrow guys!

How about trying to talk Monster into sponsoring a lounge with maybe a wet bar and snacks in the same area as the meet is happening.I prefer to ridicule and criticize them.
Two ... two ... two wins in one!

The problem is we're talking about a headphone that aspires to be in the "World's Best" category. One would think that the typical amp in that intended usage is a very high quality one --- which means it should have a low output impedance.
That's true. A headphone designed for use on a low output impedance/high damping factor amp could rely on the amp to do the damping. Headphones that are designed for 120 Ohms have to provide their own essentially passive acoustical damping. That means you are going to get various phase artifacts as the acoustic damping poles and zeros fight with the various resonances in order to get best performance without the help of a low output impedance amp.
If the cans were designed with the idea of a low output impedance amp which will provide the damping, headphone designers wouldn't have to play a bunch of acoustic games to damp the driver which essentially introduces reactive impedance schmutz.
But! Here's the worst part, IMHO, no manufacturer I've found EVER represents the specified output impedance in thier specs, so you really don't have any idea what amp impedance the cans are designed for. For example here's the beyer T1 specs:
Technical Specifications
Transducer typeDynamic Operating principlesemi-open ConnectorGold vaporized stereo jack plug 6.35 mm Weight without cable350 g Frequency response5 - 50,000 Hz Nominal impedance acc. to IEC 60268-7600Ω Nominal SPL acc. to IEC 60268-7102 dB Nominal THD acc. to IEC 60268-7< 0.05% Power handling capacity acc. to IEC 60268-7300 mW Sound coupling to the earCircumaural Average pressure on ear acc. to IEC 60268-72.8 N Cable length3 m / double-sided balanced cable (6-core)
They go to great lengths to tell us that they are using the IEC spec, but they don't tell us what impedance is being used.
So, if you want better headphones in the future, we ought to be complaining about manufacturers limiting the performance of their product by designing around 120 Ohms, and encouraging them to go ahead and build 0 Ohm headphones.
