Question: I plugged them in but no sound....any tricks to turn it on?  I have a blue light but no sound!
Document: I plugged it into my MacBook and nothing happened. The sound continues to come out of the built-in speaker in the laptop. The product came with no directions. There was no apparent way to turn it on - when plugged into the computer, a blue light went on.
I am keeping this speaker because the sound is great, nice and loud for such a small device and because it is super easy to use, just plug in and it works. But I HAD to take off stars for the following reasons:1) The little blue light on the front of the device is so bright! I use my laptop to watch movies/tv sometimes and that's usually in a dark room. I wish there was a way to turn it off.
)Similarly light and portable to a laptop, the X-Bass can be easily stowed in a pocket, backpack, bag, etc. and brought out if you find yourself in need of better or louder sound (or both).It's a plug-and-play device, so seconds after it's plugged in, it's generating sound... and decently loudly too!It has two driven speakers, and 1 "passive" sub woofer.
Plug it into the usb port and, all of a sudden, your laptop seems to have limitless sound capability. I had to turn down the sound quite a bit. Ordinarily the speakers in my laptop don't provide nearly enough sound. Now, I can listen to just about anything and hear it clearly. Also, easy to carry and install.
I bought a stereo system at twice the price hoping to use it to amplify my laptop. This little speaker is louder and better sound. You can feel the bass. The little kickstand really works great. It looks neat also sticking out the side of my laptop. The light makes it look android like. great little speaker.
The JLab USB Laptop Speakers is a great light-weight speaker if anyone is not satisfied with their current Laptop/desktop sound quality and amplitude. The quality is great, and you may not believe this, but very sturdy, and compact. It has a very strong cable to support the speaker in many positions. I highly recommend this to anyone looking for a decent speaker for a decent price. By the the bass is incredible!
Plugged it in, sound was good, I was really digging it, then it died.The end.Had a good few minute run though.That's gotta count for something, right?Haha no.
I love this product. It sure gives laptops better sounds than what speakers that come installed on laptops. Very rich sound and my computer picked it up the first time I plugged it in. I would recommend this for any laptop.
Arrived quickly and plugged it in and tested it. The sound was great, much better than what I can get out of my laptop. Look to use this for watching movies/shoes on trips and we have always had issues being able to hear. Like the size and ease of use.
It was the same as with Windows. I just plugged it in. I then had to go into the control panel and make it the default sound output. It was plug and play, with no drivers and no reboot needed.The sound is very nice. I'm not a true audiophile, so don't expect much from me in that regards. But I do think that it sounds nice. Not that I'm allowed to do much listening at work.
Answer: Pretty simple! Whatever it is you're using, you have to go into the sound settings and set it as the default sound output device. So for PC, go to the Control Panel, Sound, and pick it under the playback tab. Same goes for it not working with any other application like Skype. But changing it in the control panel should fix for most, if not all!Should be listed as "USB audio device" .
