I bought the T90 yesterday. I connect it to the iPod and it sounds fine.

  I have read many reviews of people using high end IEM with tube amp. You shouldn't judge them by their design but by how they sound!

  The Pro version of Etymotic Awareness! is $15, you are using the lite version thats why it is free.   It won't work properly with your headphones. You are better off getting their original app, I mean it's only $7 and it is constantly updated. The Etymotic version haven't been updated since...

  I am curious about the tube amplifier, I was looking at the Little Dot MK III amp's photos, it looks so cool in the dark!   I have been using the Audyssey app for the last few days, I am loving it more and more. It is not an EQed sound, they use some type of oversampling that makes mp3...

Thanks for the quick reply!   I guess I will have to go down to my local headphone shop and sample it, and if I do buy it I may have to get a good amplifier. I listen to my music either with the iPod or my laptop, I travel a lot that's why I need something I can carried along with me.   So I...

  I bought an iPod/iPhone compatible cable from Shure with mic on the cable (Can use that for answering phone call). It can also use the mic on your iPod Touch 4/5.   What it does is to amplify the environment sound (can be VERY loud, so be careful of your setting) so you can hear it while...

How is the bass compared to DT 990? What about overall sound quality, is it a little better or a whole lot better than DT 990? T90 is 3 times the price of DT 990, is the price justified? Can I use T90 with iPod Touch without an amp? If an amp is needed, is Fiio E11 good enough? Thanks.

Yes with an iPod Touch you get to do more than just playing music. I use this app 'Cleartune' for tuning my musical instruments. A chromatic tuner cost more than a hundred dollars, this app is only a few bucks! Also, do you play games? Music games like Groove Zero will rock on a good headphone...

I am using Shure 535 IEM.  I know it won't be able to emulate a full size can.  So, forget I asked, people were telling me on another post that it won't sound like the real thing.

  True, but the best apps are all on iOS, and they are cheap. Piracy is rampant on Android and developers are reluctant to make apps for that platform.

It's called digital waveguide synthesis: http://en.wikipedia.org/wiki/Digital_waveguide_synthesis   It has been used for synthesizing acoustic musical instruments for more than a decade. Maybe someone should applied this to headphones, it may not sound 100% accurate but as long as it gives an...

Damn, I actually like the simulated sound of T90 and Hifiman 500.   Isn't there an acoustic physics synthesizer technology? Maybe it can be use for simulating the physical design of the phone. 

Hello! I am getting interested in buying a pair of T90 but it is pricey and I want to make sure before taking the plunge.    Can someone here with an iOS device download this free app "Accudio" and run the Headphone simulation for T90? Does the simulation sounds like a T90 signature? Thanks...

Ok I have downloaded and tested Accudio, comparing it with Audyssey it doesn't sounds as good. I switch between these 2 apps playing the same song, Audyssey just sounds more refined and clean, with an authentic hifi sound to it. Accudio is not bad but just sounds like regular EQed sound.  ...

Quote:   Hey thanks! I am going to download and compare it. $5 is nothing considering that I am going to spend hundreds getting a new headphone and amp! 

Quote:   Why? Do you hate Apple's product?   This Audyssey app is really good, I mean seriously, this is not a gimmick. Don't be fooled by the $0.99 price tag. Find someone with an iOS device, pay him/her a dollar to download this app and test it with your headphone (make sure it is...

Sorry I was referring to the Audyssey App.   You guys need to try this app!! Turning it on and off makes a day and night difference with the Shure 535. This is the best $0.99 I spent in my life! It even has this high/low and bass/treble adjustment setting feature, but it sounds fine without...

THANKS! This is EXACTLY what I am looking for, and it's got Shure 535 profile! I am going to download and test it. I will report back later.

OK DT 990 it is then!   I've heard this headphone needs a very powerful amp to drive, which is why I am buying the Fiio E12 which is capable of outputting 850mW. Is the E10/E11 enough for this headphone? Or should I get a tube amp? The cheapest one I found is a Hifiman desktop tube amp, is...

I am a little confused about the DT 990 and it's pro version, which one is better? The pro is a lot cheaper but uses plastic instead of metal for construction, and from what I read, the pro is also uncomfortable, with a smaller soundstage because of bigger bass? Is that true?   One more...

I like the look of K550, people described it as a close can that sounds like an open one, is that true? What I worried about is the amount of bass, will the bass be better than the Shure 535?   I found a really good deal for Beyerdynamics T90, will it be suitable for me? There's not a lot of...

Hi and thanks for recommending PSB M4U1, I haven't heard of it until now. It looks very interesting, it's just a shame that this headphone is very ugly to me... It has TONS of good review everywhere.   What I hate about Shure 535 is the exaggerated mid. When I bought it, I was hyped up on...

This is my first post!   I am not an audiophile, I have only got a pair of Shure 535 IEM that I use everyday with my iPod Touch. I bought it after reading reviews from here and elsewhere on the net. I hated it at first but I am now used to its sound signature and learn to live with it. This...
