I assume it's okay, but I'd hate to blow out the small amp with too much power. The iPod charger is probably 450 to 1000 ma; I don' t know the output of a PC or laptop USB port. Can anyone help me? Thanks!

There have been lots of people asking about the differences between these two, but no definitive answers that I've seen. (Mostly people point out the slightly larger cups in the i version, which "theoretically should equate to better soundstage," but I haven't seen a head to head comparison from...

There's a note on Apple's website saying that the new Shuffle's rechargeable lith ion battery is NOT replaceable. Was this the case with the 1 gen Shuffle batteries? I'm sure third party providers will find a way to crack the case and change out the battery the way they did for the 1 gen...

Some people have suggested that the thinner Senn PX100 pads help open up the treble, and someone else posted that the Radio Shack pads might do the same thing. (Plus, either pad could then be quarter modded.) It would be much easier and cheaper for me to pick up the Radio Shack pads rather...

I guess technically the Bo$e system fits in the portable audio category and belongs in this group. I'm looking for something similar for my living room, but I can't see paying Bo$e prices for average sound quality. However, I don't mind paying close to that price for stunning quality...

Now THERE'S an easy to remember model name. Not at all like that hard-to-remember "Shuffle" or "Micro" or anything else without a number. Is Sony deliberately trying to scare away customers? This is the mp3 player that looks like a large coin, not the one that looks like a cigarette...

I'm seriously considering moving from minidisc to the 4G iPod, but I have a question about the music library. I've got close to 30GB of free space on my rather old PC, but unfortunately it's split up into three partions (about 12GB each). I can't remove the partions because it's an old FAT...

Let's see if I understand this correctly: To transfer a CD to an iPod, I have to use iTunes to rip it to my PC and leave it in the library for synch-up to the iPod. If I want 20 CDs on my iPod, I have to copy and KEEP 20 CDs in my library. If I delete a CD from my library, it will be deleted...

I'd like to hear from someone who has both of these cans (JMedieros?). The price is pretty much the same for both, and I've read good reviews on both units. I need these for work, and want some isolation and no leakage. The most important thing is sound quality when plugged into a portable...

eCost has em both for arround $30, so I'm gonna pick up one or the other for plane trips. I expect that the EX71 will have better isolation and not as good sound, whereas the 200s will probably sound better and isolate less well. Am I correct in my assumptions? I'd really appreciate hearing...

I searched the archives and didn't find anything. I'm surprised this topic hasn't come up before. How does the sound quality of the iPod compare to a mini disc player? I'm not talking about mp3s which are slightly compromised to begin with. Instead, how does a CD copied to an iPod vs. a CD...

I've read in a couple of different reviews (not just at Headroom) that Grado SR80s really need an amp for use with a portable device. A quick search of the Head-Fi archive suggests this probably isn't true, but I wonder why this rumor persists if there isn't a little bit of truth to it...

In an earlier thread, someone suggested that the KTX Pro1 uses the same drivers as the KSC-35. This is great news if it's true, but I have one question before I rush out to Borders. I've got the older KTX Pro, and IMO it doesn't sound nearly as good as my KSC-35s or KSC-55s. My question: does...
