Summary: i was so underwhelmed with these portable speakers. Yes they have a breathing tune port which does help with the Bass, but don't expect much from these. As a 33+ year bassist, I think I have a good grasp on Speakers. Also for many many years I was really into Sony products.
Sound quality is good - annoying hum/buzz when computer sleeps
20 December 2013
Summary: Performs well; when computer sleeps, there is an annoying hum or buzz when the computers goes into "Sleep" mode. Online rooms suggest this is due to poor grounding or poor shielding. Either way,...annoying, and so I have replaced them.
Poor sound, even worse installation. Keep looking.

Summary: Very tinny and weak sounding. Installation is an utter disaster. Every other speaker on the planet has tabs that fly out, these have a rectangular bracket that requires you to disassemble the speaker and remove the driver in order to install them.
Summary: These speakers seem okay at first, with decent volume and clarity, but every time a song with any bass comes on, you have to turn them down quieter and quieter until the distorted noises stop. I would only use them if you're going to be very close to them.
