Ideal por my use

To replace defective speakers on a laptop computer.
Does its job for the use that I've (mostly video) especially at this price.
Obviously we should not expect an extraordinary sound quality.
As in other reviews, I advise not to open the bellows because the difference is imperceptible and as congestion remains minimal.
I enjoyed the double thread (jack and USB) for separating them can be loaded while leaving the connected jack.
