Question: Do these speakers work with a Lenovo E520 Thinkpad?
Document: At low volume, the sound quality is slightly better than the stock Lenovo tablet speakers but at higher volumes the sound quality is lousy.
Folks,I tried these speakers on two different Computers  (Win 7 and Win 8.0);One unit a Dell , the other Lenovo. Both have a wireless mouse as a pointingdevice. On both units a buzz (* interference) came though the speakers whenone would move the mouse... So, back it went to Amazon.Amazon - always great and easy to deal with on all items. Yet the product inmy setup is below expectations.
I was hoping to receive a set of speakers that would allow me to play some music with a slightly better sound quality than my internal laptop speakers. Unfortunately, the speakers created a constant, weird noise as soon as they are connected to the USB power of my Lenovo laptop. The problem slightly improved when the speakers were connected to an external USB battery pack but the background noise was still far from tolerable. I had to return these speakers.
Note: I would love to love this speaker set, but it has inconsistent performance with various devices. I received a review sample and was pleased by the sound when I plugged this into the phone port on my ThinkPad T61. The sound was clear and I could hear every note on the album that I use to test speakers (Miles Davis'Kind of Blue). I use that album because the instruments in the ensemble cover low, mid and high range frequencies.
I like the priceNot the greatest quality--very very basicMake sure these speakers will work for your deviceAnd you'll be happy
I am amazed that the quality is so good from such small speakers. good value for the money. They work great
these are perfect, small, and make the small laptop speakers boom. A must have for the person who needs to work on a budget
These little gems work great. I do not require perfect sound and these speakers are better than i need. Space savers too!
Nothing flashy about these...they do the job...nothing great but small portable and they work. Nice extra set of speakers for a laptop.
I use these speakers with my computer at work. They work really well and can get very loud, considering their small size.
Answer: The laptop I was using the speakers for was actually a lenovo z565 idea pad. However that laptop broke and I'm still currently using the same speakers on a PC I recently built so to answer your question, these speakers should work for all laptops as long as they have a USB port and headphone jack
