Question: received a cable for single speaker... how can i find a dual mini usb port cable?
Document: I bought these in February and wrote a very positive review, impressed with the sound from such a small set of speakers, their portability and the impressive battery life. Two and half months later, one of the speakers has crapped out, won't accept and charge and when plugged into the usb port on my computer only emits a loud clicking sound. So, essentially I've only got one speaker which will play the right channel from a stereo file.
I've tested these on several genre's of music from country, to rock, R&B, rap, and dubstep and they all sound awesome. They get pretty loud too. Like I said one speaker is a little iffy so the sound goes in and out, but the other one sounds awesome. Definately worth $40. They charged completely in about an hour, maybe a little less and they've been playing now for about 3 hours and are still charged. They recharge via usb port and connect via audio jack.
I was very excited about this mini speakers and frankly comevery handy whilst travelling and easy to manage as far as recharging as done with USB port and the sound is satisfactory and the astonishing and negative is the cable as the wire connecting are very fragile and my cable is broken but havent hurd a response from the manufacturer or else I will file a complaint with product safety.Hope they replace the cable asap.
For times when this will be plugged into a computer, it would be nice if I only had to plug in one cable.4 - Sound quality is just, OK. I can't really take away a star for this but it's worth mentioning. I've sold stereo and speaker systems for a couple years in the past and I know what I'm talking about in this area. Buyers need to understand that no matter what the mantufacturer says, a single tiny speaker can only provide you with limited sound quality.
June 2011 update: Uh-oh! they have stopped working! I need to double check them, but last night they stopped working on my kid's laptop. When I have time I will try to figure out why (I made sure the usb portion of the cables was hooked up right, the power switches were on, and the minijack cable was plugged snugly into the "speaker output" not the "microphone input" jack.
I bought this a few months back, and just opened it. Plugged it in to the USB port to charge it. After 5 hours, one speaker's indicator light turned blue (meaning it's charged), whereas the 2nd speaker was still red. I left it connected overnight, but it didn't change to blue at all. I unplugged the USB cable and turned on the speaker, but it didn't work. So I conclude this speaker's battery is dead! It will only work when connected to the USB power.
This is just my opinion.Is it a portable speaker that amplifies sound better than your laptop? yes. Does it do this well? yes. Is it better than the single x-mini speakers that are cheaper, smaller and more portable? no. Is there a huge quality difference between this, and the more expensive, slightly larger portable speakers like the mini-jawbone, and the beats Pill? yes, there is a huge difference in quality.
maybe it's the rechargeable lithiums that get them excited. rechargeable is cool but sound is better and, besides, the speakers recharge through the usb port on your computer. i attach my speakers to my ipod when traveling. the computer usb port requirement is not as convenient as a package AAA batteries. and then there is the sound!
It is a nice portable speaker but the volume control wire got a loose connection in a few days and I returned it.The sound quality is good for cheap portable speakers. Makes movie audio and voices much better than native laptop speakers.I had the x-mini single speaker before I got this and it does almost the exact same thing, in a smaller package and cheaper price.
Loud and great battery life. The distance between the usb connection and the audio jack connection is extremely small and nonadjustable. If you do not have a usb port close to the audio port, a usb extension is definitely required. So far it isn't a problem for me since the battery life is so long i don't need it to be charged when i'm using it.
Answer: My dual mini speakers came with a single cable.  It has a 3.5 mm jack on one end to connect to your device with music and the other end of the cable splits into two USB ends.  If you did not receive this you may have to speak with the manufacturer.  These are not the usual cables you find at your electronics store.
