Rating: Summary: Speakers stopped working days after warranty expired Review: I am an instructor. I needed a speaker system with a very small profile for international air travel. A friend of mine, who works for a major computer company, recommended these due to their size (though he did warn me the sound quality is average).
The speakers are indeed small & light - and they conveniently fit into my computer bag.
The sound is average, as I was warned.
The UBS connection cable is too short - which is an inconvenience.
But most disturbingly, the third time I used these they stopped working properly. Unfortunately it was 2-weeks past my warranty period. Their malfunction may have been a coincidence, but under the circumstances I cannot recommend these. Even when they did work, the sound wasn't up-to-par.
Do yourself a favor: look for an alternate model (there are many choices out there, in prices that range from $30 - $80). Just remember to go with a USB-powered model (USB power is a MUST!).
Rating: Summary: sounds worse than the laptop speakers Review: The builtin speakers in my laptop sounded better and louder than these speakers. The Sony's highs are muddy and the volume does not go very loud (yes my laptop volume was all the way up). If you want extra laptop speakers for your presentations with clients look elsewhere. All we wanted was a decent quality sound that was a little louder than our laptop speakers and these speakers definitely did not deliver and will be returned. If you need ultra portable sound and your laptop speakers are broken or sound much worse than average laptops (we have nothing special), then maybe this would work for you.
