Question: Does the speaker have plug for Headphone ?
Document: Great sound! I am impressed with these speakers. I had no way of plugging in my headphones or other speaker by regular headphone jack because it shorted out on my laptop. I love these.
This means (stating the obvious, again...)= cannot be used w/ your MP3 player to serve as a external stereo speakers= cannot connect headphone to the speaker (connect headphone to the computer instead)Other comments--------------- Bought two. One worked, and the other was bad ("USB device not recognized by computer" (running Windows XP, in this case).
I purchased these speakers not from amazon but from a store. Just to let you know.Probably like some of you, I went with the USB digital speaker so I could still have the regular speaker jack on the computer -the speakers have no headphone jack- for use with my headphones when others around me ask me to use the headphones. Okay, no problem there, right?
They're light-weight and are purposed for portability.CONS: Where they shine in quality they lack in function. (I guess they had to skimp somewhere). Instead of including certain basic features, they must be outsourced to the computer or host device. Some of these problems are:  1. There is no auxiliary/headphone input. The computer's headphone jack will have to suffice. This creates other problems, such as 2. Speaker and headphones transitioning is a big hassle.
)- Not a fan of USB speakers. To be fair, this was the only USB speaker I've used. And it was messy. The volume was difficult to control. And the computer became 'wonky' when I plugged or unplugged the USB speakers. I found that I had to reboot my computer each time my computer became 'wonky' as result of using these speakers. Worst of all, if I inserted my headphones into the computer's headphone jack, these speakers kept on playing.
You get solid sound from these speakers, which are good for office use. However, gave it 4 stars instead of 5 because the volume control and MUTE buttons require a good amount of force, so you end up tipping the speaker over since they're as light as a feather.One other thing to consider with these USB connected speakers is that unlike their 3.5mm sister product, they do not have a headphone jack and the volume is not a knob but buttons.
I have to restart my computer to get them to work, then when removed have to restart to get the laptop speakers to work. Does not work by changing in the control panel with windows Vista. Crackling sound and hard to control volume. Better with speakers that plug into the headphone jack.
I bought the Logitech S150 Speakers and let me say they work great for something that is small and cheap.The only thing I found is if I plug my headphones into my computers headphone jack the speakers will start acting weird but it stops and the speakers work fine after that.Good speakers for a great price.
Was honestly surprised when these showed up. They are much smaller than the picture makes them out to be which was actually a bonus. They are so simple to set up it's a joke. Just pop it into a usb port and you're done. For the size and the price the sound is actually very good. The volume gets as loud as i'll ever need and they don't really distort at all. My only feedback would be to include a headphone jack so I can plug my headphones in.
So far so good, the sound is great, and the fact that you only need one cord is great, you can plug the speakers into a USB port on your computer and totally avoid needing a headphone jack or extra power cord spot everything works right through the USB. I plugged them in on my Windows 7 computer waited for it to load and they were ready to go with no additional setup required.
Answer: Not that I can find.
