mobile usb speakers ironically not practically mobile
pros: decent sound quality when it works, no extra power adapter or battery needed.
cons: uses usb connection only, sometimes there are usb connection problems when you move the laptop around causing sound to drop out and the V20 audio device to disappear in windows.
analysis: mobile speakers ironically not very useful in a mobile environment
if you just plug it into your laptop's usb and you don't move the laptop around, then you're good.
but say if you're in your car and you want to use bettery quality speakers than your laptops built in speakers, the usb connection can be a problem as it may cut off causing you to have to restart the media player's application in order for sound to play back again. (unlike using headphone plugs, when moving your laptop around, you can't just unplug the usb and plug it back in)
Wonderful--if only they wouldn't move!
These speakers are awesome. I have a Dell m1210 laptop, which has horrible built in sound.
By contrast, I plugged in my Logitech V20 and boom--everything sounded so much better. I'm not an audiophile, so I can't give a rating about the frequencies and such, but, I listen to music 6-8 hours a day (usually a combination of indie rock, drum and bass, and female vocalists), and I was happy with these speakers.
There's a small annoyance in how Windows handles USB speakers--you have to restart your audio player whenever you unplug or plug in the speakers. But my much, much bigger annoyance is that the speakers vibrate.
When I'm listening to something with even slightly heavy base (I'm talking Regina Spektor here, not rap) at a decent/loudish volume, the speakers will actually move while on my desk. And continue to move, onto the floor, at times, or knocking stuff off my desk if I'm not paying attention.
Absolutely ridiculous. Luckily, I'm a college student, so I have plenty of heavy textbooks around--I just put one on top of each speaker and problem solved. But, I would be happier if the speakers had better traction.
All in all, great purchase, especially for the price.
portable, sounds great
Pros -
These speakers are perfect for traveling in their very nice little case. I plugged them in and they sound great. They look great and stand up well with rubber coated feet. They display a large green volume bar on the screen while adjusting volume. Nice smooth base that doesn't sound distorted when turned up.
Cons -
The top two or three volume levels severly distort the sound and are unlistenable, this may be my computer and not the speakers. They are still plenty loud a few notches down though. The plug from the 2nd speaker to the first doesn't always seat right so no sound comes out of the 2nd speaker until you adjust it. It would be nice if it would reliably make a solid connection. My biggest gripe would be the control buttons on top. They require a decent amount of pressure to actuate and there is no feedback so the only way you know they are working is watching the volume on your screen. Overall a great product for traveling with my laptop.
My setup: Xotic PC Force 3551 laptop (MSI-1651 platform) - on board sound card.
Great portable USB speakers...
I have a Lenovo Thinkpad T61 laptop, whose sound output left much to be desired. I bought the Logitech 970155-0403 V20 Notebook Speakers to watch TV shows, movies, music videos and instructional videos online.
Overall assessment is that these speakers serve my purpose VERY WELL. The speakers enhance the laptop's sound dramatically. I like the fact that the speakers connect to the laptop through a USB port. The speakers have a good form factor, which makes them easily portable.
The only downside (and it is only a very minor one) is that if the laptop is put in Standby mode and then turned on again, the volume controls on the laptop fail to control the speakers' volume (this issue is easily solved by using the speakers' volume controls, that are conveniently positioned, on top of one of the speakers). Once the laptop is rebooted, the problem goes away. There may be a way to fix this, but I have not spent time on it.
All in all, I am very pleased with the sound quality, portability and convenience of the speakers.
Small problems
The speakers sound very good for their size. No complaints. Two issues. The buttons are stiff and not helpful. Plus, my speakers only work after the Toshiba notebook boots and then the speakers are plugged in. If they are plugged in first, the notebook won't boot up. Still working on that.
