Can I listen music from this device without any power connection? In this case, which will be the resource of energy that it would need?

*4 AA batteries will last approximatly 72 hours. Which means if you take a 10 min shower everyday with STORMp3, your batteries will last over a year.

Absolutely not. You'll need a receiver or a power amp of some sort. (And no, not an iPod.)

The key question is whether the device will play a single track continuously, i.e. in a loop. If so, I think we can fool it by using a power only USB cable connected to a charger, not a PC. Can someone answer the first part of my comment?

I can't imagine it powering a laptop, don't laptops need way more energy than an iPod or cell phone? I wouldn't recommend trying it. I would say it's a REPLACEMENT for powering off a laptop.

You can use it without power adaptor if you plug it to computer using USB cable to control your software synth in your computer. It is just a MIDI controller therefore it does not have any built in Sounds. You can also use MIDI cable to trigger your external MIDI sound modules. You may need power for that purpose. I tried using it to control external midi devices without power adapter. As long as it is plugged in to computer using USB cable, it works for me.

No.. it's no the most efficient use of electricity. Forking over another $150 for a receiver just to connect headphones?? Seems like these LCDs are skimming on the necessities. In any case, I appreciate your reponse Bubba.

No, it requires power. Also it is OS dependent. For example it worked fine on my iPhone 4 with iOS 5 (I think), but when I upgraded to 7, it stopped working. Apple stopped allowing devices to draw power from the iphone. My guess is that it is the same with the ipod touch. The interface is based on the iOS. There is neither a battery, nor controls on the HD receiver, nor a speaker, though there probably is a headphone jack regarding controles there is one exception. There is a control for tune tagging. So read carefully.

If you have blue tooth. Never tried just connecting to listen to music. I'm sorry. You can charge from lap top.

Just use speaker cable to hook up to receiver/amplifier. Speakers draw power from amplifier so no power cable needed.

Yes it needs power and it comes with the 5v power supply included that plugs into it. I was very satisfied wit the unit. I amplified the analog output using cheap computer speakers then pluging headphones into the jack on the computer speakers. The pictures and whats included in the box is shown out on the amazon site.

No power to it (Nyrius) just your devices. We use it for optical sound between cable, AppleTV and BluRay.

No it does not require battery power. It is basically like a pair of earbuds attached to your iPad or Mp3.

Hi. With this device, you do not need any external power. The device brings it all included and takes what it needs directly from their computer. It works excellently. Regards. Vincent.

You can but that will kill the internal battery slowly. Get something without battery and go wall adapter only. Soundfreaq platform 2 is my recommendation

You Can't use this speaker as Passive only Powered, However there some passive models from qsc

Yes you do--it is a source component. You can listen to it with headphones without an amplifier, but it will definitely not power any speakers as it only has line voltage.
