This is a bit of a niche question, but I'll shoot.   I recently acquired a Macbook Pro Retina.   On the specs page (http://www.apple.com/macbook-pro/specs/), under "audio", it states:   Support for audio line out (digital/analog)   Image: http://i.imgur.com/Equbn.png    ...

I love my K550s. The sound is, to my ears, pretty amazing. But with their sensitivity, durability, and looks, I'd love to use them outside as well as indoors. However, the cable is something like 3 meters, which makes it very awkward to use them out and about. My search for portable circumaural...

Just got an iPhone, looking for free, high quality streaming radio for listening over wifi. The higher the bitrate, the better: 256 Kbps and up. Also looking for a free app to organize said streams.

Hey there.   I just bought the K550 headphones on Amazon. Now I'm looking for a travel case that would fit the headphones and protect them, mostly for carrying them around in a backpack.   Also, any suggestions for a small cable manager would be appreciated. 3 meters is a bit long for...

I'd like to pick up a pair of these for listening on-the-go and without amplifiers.   I would also like to use them for my college music production program.   I'm sure they're revealing enough, but are they neutral enough for such work?   Frequency response graphs would be great if...

I'm looking for a neutral, comfortable, closed headphone to be used for music production and listening through a macbook pro and virus ti2 synthesizer. I really like the idea of the SRH 940, but I'm open to other options. Have any suggestions in the $200+ range?

I'm about to buy the SRH 940. I'll be using it with a Macbook Pro for music listening and production, and with an iPhone 4S for music listening on the go. Will an E17 be a significant improvement over the Macbook Pro's DAC and headphone out? How about compared to the headphone out of the iPhone...

Dear Head-Fi,   I've never owned an "audiophile" cable, but I just ordered the Foxl v2 off Amazon, and was looking to upgrade.   The cable I'm using now is an $8 cable from Mediabridge. I like this cable for the screw-on connectors, which helps prevent bad connections.   Basically...

I'd like to start a collection of stylish portable headphones with good sound quality to own and resell to college students.   I've just purchased a Crossfade LP to start my collection. I plan to add a Skullcandy Aviator, and possibly a V-Moda M-80.   What are some other portable...

I remember reading somewhere that if you get customs too young, your ear canals will change shape slightly as you finish growing and basically defeat the purpose of getting customs. Is 19 too young?   P.S. The customs in question are the ES5s, which use heat-molded vinyl tips. If that...

I remember looking at mp4nation's site a few months ago and seeing a pre-order for the second batch of S:flo2s.  I checked back today and it doesn't seem to be listed at all. http://mp4nation.net/catalog/nationite-media-players-nationite-sflo-c-36_58.html   Where'd it go?

Hi.   I'm looking for the best portable amps under $250 that i could use to power the ATH-M50 headphones using the headphone-out of my Cowon J3.   In the meantime, I'll look for posts about amping the M50.   Thanks in advance.

I know this doesn't belong in this section, but there's no other place to put it. Also, I figure that people who are into portable audio might have some insight into portable speakers.   Here is what I was looking at...

I want to start saving up money for a top-tier custom in-ear monitor for use with my Cowon J3. Right now I've got W3s and I'm loving them, but I know my music could sound better, and I want the comfort and isolation of customs.   FWIR Impressions:   ES5 - Pros: Clarity, build quality...

Hey, I have to find something for $50 or less to put on my Christmas list. I already have good iems and headphones are on the way, and I'm saving up for an amp. The $50 can't be used towards a purchase, it has to be on its own. So I thought I'd try some cheap DIY.   I don't have a DAC yet...

Why is sensitivity so important in being easy to drive?   Just from looking at specs from different headphone companies, can you tell which headphone will be easier to drive? e.g. HFi 2400: Impedance - 70 ohms / Sensitivity - 94db DT990: Impedance - 32 ohms / Sensitivity - 96db  ...

Hey, I would like recommendations from people who have owned any of the above headphones and used them unamped. FWIRs are also welcome.   I'm looking for a set of open, comfortable, headphones to use exclusively from the headphone out of my Cowon S9 mp3 player. In order, my priorities...

Which is easier to drive from a portable source? (cowon s9)

Hey I'm thinking about getting one of the above headphones, probably the 990, to use with my S9. I know that the consensus around these headphones is that despite the 32-ohm rating, they still don't sound good from portable sources, but most people have ipods. As the S9's amplifier is more...

Somebody got an idea for this? I have the IE8 and love it, but I'd like a set of home headphones that can be powered effectively from a cowon s9 (29mw/channel i think). I have the ATH-M50 (sensitivity 99 impedance 38) which is easy to power from my S9, but it sounds closed off to me. I think...
