Let the hive mind of Engadget get that for you.
"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"
Having bought a set of Ozaki 5.1 headphones with the EXACT same controller box more than 8 months ago, and having seen 2 other 5.1 headphone "kits" (box + headphones) here in Eastern Europe, just to let you know that the only difference is in the cans, although all of them have the microphone included. The biggest problem that I have had with them is that electrical interference is picked up VERY easily by the box (2.4gHz and cell phone) and I actually had to cover it with a custom made aluminum metal enclosure to get rid of it (you can't take things back here... sigh...). They are not worth it. I had a pair of Zalman's, but decided to upgrade because the foam around the cans was getting ragged, and I should have just bought another pair. Live and learn....
