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.
Summary: Bit of a buzzing sound when on standby. You have to turn it off when not in use if you're sensitive about buzzing sound. Not sure why these speaker systems insist on putting a bright led light to show that it's "on". Had to tape over with electrical tape because it was SOOO bright at night.
Summary: when i got them i pluged them in right away and they had great sound better then i thought i got them for my tablet when im listing to my music in my computer room my wife used them for her i-phone when shes listing to music in the kitchen cleaning and now i might not get them back lol so ty :-)
