Researchers at the University of California, Berkeley have created the first ever graphene audio speaker: an earphone. In its raw state, [B]without any kind of optimization[/B], the researchers show that graphene’s superior physical and electrical properties allow for an earphone with frequency response [B]comparable to or better than a pair of commercial Sennheiser earphones[/B].

how expensive were mx-400s? apparently they are discontinued and i can't find a price on google.
sennheiser is generally a good brand, but it isn't like all their gear is top shelf. also, since they are earbuds i have trouble thinking that they are incredibly high quality since even expensive earbuds aren't generally as good as cheaper, larger headphones.
still cool that the graphene doesn't need any dampening when used as a diaphragm.

i wanna see graphene studio monitors soon. that shit will be boss.
I wonder if they'll be able to get any decent low end response with a full sized graphene speaker. Seems reminiscent of electrostatic speakers. And I wonder how large it can get before it has to be dampened...

Personally, I can't wait for graphene electrostatics.

If you're talking about the picture that's the first transistor.
Just remember... Graphene, such as that used in carbon nanotubes, can induce mesothelioma.

no they don't. they don't have very large speakers or the energy needed to produce low notes. it makes your music sound thinner, without substance.
that's why if you are monitoring with headphones, then you monitor with over-ear studio headphones with a subwoofer built in.
these are what i have always used, mostly because i got a pair for free, but also because they fucking rock. [url]http://www.amazon.com/Sennheiser-HD-280-Pro-Headphones/dp/B000065BPB[/url]

iem's are always used with portability, convenience, and discreet purpose in mind. they aren't used for high quality sound.
One of the researchers for this is Alex Zettl, who was my physics professor my first year of undergrad here for physics.

"with a subwoofer built in"
what
and monitoring = trying to get a pretty flat response which isn't really that great for general listening!
and I guess at VERY low budgets IEM are better sounding because there's less material cost, not really referring to high end, when I think of value I think <30 and there's $7 monoprice IEM that sound like $27 HTF-600 which are amazing headphones

small speakers won't play lower tones that well. it takes subwoofers specifically made to play low frequencies. if you take apart most headphones that cost a bit more money there is a subwoofer in there so that you get both the bass and the high ends when you listen.
[quote]and monitoring = trying to get a pretty flat response which isn't really that great for general listening![/quote]
generally when you listen to music you want as little coloring as possible because you often want to hear the song "true" to the way it was recorded. sure, when you are recording, mixing, and mastering, you use microphones and processors with non-flat frequency responses because you may want to tone your music a certain way. however, if you are listening you want flat because the songs were meant to be heard with certain overtones, undertones, present in different quantities. the less flat your monitor is, the less you really hear the music the way it was meant to be heard.

i'm not an audiophile but i generally try and spend more than $50 for headphones. personally i like music and like to hear it as beautifully as i can. the differences between cheap iems and cheap headphones won't be as drastic, but once you start getting to monitoring headphones and pro-audio gear then you start to notice huge differences between buds and cups.
this is also coming from someone who spent a couple years studying audio engineering and technology so i'm admittedly pretty biased.

my shitty in ear headphones can hit those low notes youre full of shit.
[QUOTE=Shadaez;39918289]uhhhhhh I don't think anyone does this except pro gamer 'surround sound' headphones[/quote]
maybe subwoofer is the wrong term. it takes a bigger speaker to produce sub tones(<200hz). if you look at the frequency response for these graphene earphones you see that their response begins to take a nose dive at ~150hz, this is in large part because the speaker is just too small to play these tones. more expensive headphones have better ability to create sub tones.
[quote]that's personal preference[/QUOTE]
there is objective reasoning why you would want a flat, or at least controllable frequency response, though. let's say you listen to many different genres of music(as most people do); different genres are mixed differently. if you are listening to some hard rock, and then some country, and then maybe some dirty south rap, you will notice that there are very clear differences in the overrall tone. generally country is twangier, hard rock begins to add in more bass tones, and then the rap will be bass driven with less high tones. if you listen to these on a flat monitor, you will hear each one with all the accentuation and subtleties that were in mind during recording, mixdown, and mastering.
however, if you listen on a monitor that, say, accentuates the bass over everything else, it may compliment the hard rock, but the rap may become really muddy sounding and the country will sound way funky. so headphones with "color" will only sound good in specific situations, which is bad for general listening. that's why most headphone makers put a lot of effort in making their headphones as flat as possible.

you sure? have you done a listening comparison between them and higher tier headphones? i'v never heard earbuds that can faithfully play low tones, at least not nearly as clearly or as nicely as over-ears.

logitech is not known as making incredibly high quality audio gear in the first place. it's easy to see why your earbuds would be comparable.
just a cursory glance of google shows x530 has a response of 40hz-20khz and doesn't actually specify the response at 40hz.
[editline]15th March 2013[/editline]
i mean it's quite possible at 40hz that it is playing at something like -20dB or something stupid like that.

yeah no doubt, that sub doesnt sound like it goes any lower than my bookshelf speakers.
but i have compared my in ears to this

it hits the lows just like that (except dosent shake your entire everything)
