So been using my Fiio E17 lately on my Macbook pro 17 inch unibody (not retina). Everything plays well, except when I press on a key, I hear static / cracking sound for a few seconds. The static / cracking sound comes back when I press any key on the keyboard.   At first, I thought it was...

Oh my!! http://www.youtube.com/watch?v=BgAlQuqzl8o or on Spotify (The Piano Guys - Cello Wars) the bass part was just awesome on the HE-400 / E17

Whats the purpose of open back headphones? Why do they exist in the first place? Are they supposed to have higher sound quality since some of the sound leaks out from the back? Is this the purpose of the design?   Some disadvantages Ive found so far are it annoys people around you when they...

http://www.youtube.com/watch?v=5IVpEjJuztk has a bit of a "broken" bass towards the end. But otherwise good trailer to watch with the HE-400

Just received my HE-400's, which I will be pairing up with my Fiio E17 amp/dac.   I've tested the headphones on several songs / movies. I've been listening to a lot of classical and house music. What should I listen for? I have a pair of iPod earphones, and when I plug them into the Fiio...

If all goes well, my HE-400's should be arriving tomorrow. I will be pairing this up with the Fiio E17 amp/dac.   Any movies on netflix worth seeing with the HE-400's?   Moreover, what music would you recommend listening to with the HE-400? I don't mind which genre. It all comes down to...

Just got my Fiio E17. Pretty awesome! I can already notice sound quality improvement. When connecting the amp/dac to your laptop, what do you leave the volume settings on? i.e. laptop laptop volume at 50% and let the amp/dac control the volume?   Also, what do you leave your amp/dac gain to?

I put an order out for a pair of HE-400's. Can't wait for them to arrive soon. However, I also read complaints from some people about a faulty driver. How can you tell if the headphone is faulty? Is it a matter of hearing them out? What are the signs of a faulty driver?   Hopefully the ones...

Standard mp3 files at 192kbps is just "average"?   Where does one obtain audio files from? CDs? Torrents? Special sites? Itunes? If I am spending $400+ on cans and an amp/dac, I would like to hear "quality" sound.

Am waiting on my HE-400's to arrive! Real excited!   In the meantime, am just looking for some conversation about what type of audio files I should listen to with with these cans. I've got a library of mp3 files, that bring back memories. Will the HE-400's shine here? Or should I consider...

Quote: Isn't the Amazon listing from the same company?

Just put in an order from http://www.amazon.com/HiFiMAN-HE-400-Planar-Efficiency-Headphones/dp/B007ZG32I4/ref=sr_1_1?s=electronics&ie=UTF8&qid=1347680485&sr=1-1&keywords=he-400   Should be fine? Concerned about the "fake" products being sold. But then again, if head-direct is a sponsor here...

The other benefit (via Amazon), is the ability to track the order. The downside, is they don't sell the velour pads

Im looking to purchase a pair of HE-400 headphones and the Fiio E17 amp/dac. Should I get these from Amazon or directly from the supplier, i.e. http://head-direct.com   Any benefits?

Chewy4: So I guess the comment made by Mad Lust Envy about "I can attest to the HE400 sounding good off the E17." is really about volume and nothing else right? No significant "bang" with sound quality.

Which amp and headphones are you using?  

I am thinking of purchasing a pair of HE 400's. However, I am in the middle of deciding whether I should include an amp in my purchase...   Does having an amp make a real difference in sound quality?   I will end up using the HE 400 alongside my macbook pro laptop while I work. Mostly...

Are there other amps I should consider with the HE400's?   Chewy4, any updates? Does an amp make a "significant" difference in terms of sound quality?

What amplifier should I get with the HE400's? Thinking of the portable E11 or should I consider something else like the E17 DAC. I like the E11 because it seems portable. But worried about the quality not being as good .   Second, is it "mandatory" that I have an amplifier with this? Does...

I'm thinking of buying the HE400's, but reading this thread, it looks relatively new: http://www.head-fi.org/t/586885/new-hifiman-headphone-he-400-is-out   I plan on pairing up the HE400 with a Fiio E11 portable amplifier. Good combination? Or should I pick a better amp? I've got a laptop...
