Are these phones efficient enough for use with a portable player (Pono or Fiio X5) without an outboard headphone amp?

YesI use mine with iPod nano all the time the volume is outstanding and the sound superb. I would assume they would work the same with any portable player.

I use my HD600's all of the time with my iPhone 4S and do not need or want an amp. They work well.

The answer is yes. In fact I got the phones mainly for use in my flying trips to Italy. I am very happy with them and think they deliver the goods! One note: they sound best after a break in period. I just finished letting them play my radio Classical station for three days.

With this player you don't need a headphone amplifier. It can drive headphones rated from 16 to 300 ohms (that covers pretty much all of them). Anyway, in theory it should be better to use the line out, but the line out of the X3 is very loud.

If you are asking about playing music without some sort of headset then I would say this: I don't think any phone really sound good. I use either earplugs or I go with wireless speakers. Phone calls are no problem with the sound.

Hardly "wasting" money in my view, they're a great set of headphones. But you'll get better results using high-bitrate or uncompressed audio and a better output than Apple, like a Cowon music player. There are also small portable amps you can use with the iPhone. The iPhone audio isn't tops but it's not that bad either.

Yes, almost anything can drive these. Even an Iphone or Android phone can drive these, just don't expect super high volumes (100% volume with these on a phone will sound like 65-75%). If you want to drive them higher, you can get an amp to really take advantage of these headphones.

They are great speakers, exceptional really, but they do not have an amplifier. Your smart phone alone would not have enough power to drive them. You would need to connect it to an amplifier of some sort in order to use them. Also, the cost listed is for one speaker only, you would need to buy two in order to get stereo.

Sure, they'll work, if all you want to do is listen through them. They don't have an inline microphone or controls, so if you want to use them on a call, you'll still have to raise the phone to your mouth in order for the other person to hear you.

Im not an expert, but if you are going to use these cans with your phone or any portable device, well then you will have no problems (you will not have enough power to blow them anyway).... but if you want to amp the sound you might have some difficulties. I red that Grado improved the Bass from the S60 model to the S60i model, the i version has a less precise bass, but it is more musical. but, keep in mind these cans are bass light.if you want to get more info check this webpage, the review section is great, and it may help you with other concerns. http://www.head-fi.org/products/grado-sr60i-headphones Im not an expert, but if you are going to use these cans with your phone or any portable device, well then you will have no problems (you will not have enough power to blow them anyway).... but if you want to amp the sound you might have some difficulties.

Almost anything will drive them. I've used them connected to a cellphone and they reach a moderatelynloud volume. You Asgard will be perfect!

Just buy the adapter for the device, they're compatible with just about everything. Not sure you'd need an amplifier unless the phone doesn't have one built in.

No, and they arent powered so you'd need an amp/receiver to use with ipod etc, they've got the kind of jacks for using speaker wire

They have good built-in mic. I use them for both music and call. Worth to buy.

Yes they will, however i have noticed that you should get a headphone amp for these as the amplifier in most smartphones never have enough gain.
