Document: I am not sure what this additional cord is for.I am not referring to the cord for charging the speaker.Anyway, it is a very nice product so far, and I am glad I purchased it.Thanks!
I ordered the GOgroove BlueSYNC BR2 to have a good portable speaker with me at work or while I'm cooking. This thing is great. It's bigger than I expected but not too big. I really wanted a true stereo speaker and not one of the little single speaker units, this delivers. For it's size it has a very good sound, plenty of low end and the highs are not muffled.
What more can you expect from something for this price! Bluetooth enabled makes itunes function great with this speaker, although if you stream music, the bluetooth usually isn't fast enough to transmit the sound without cutting out every once in a while, even with excellent broadband. The only thing I didn't like about this is that it's not made to last. The cord broke after a few months of gentle use and the sound gets distorted easily.
I got this because I wanted to play music at work without having my phone out on my desk. The buttons take some getting used to but the sound quality is great. It works through my desk drawer and through walls when I grab my phone and walk away from it to go to the bathroom or breakroom. I love that it came with a micro usb cord which is the same as my phone. I just wish it came with a wall plug.
bought them for a gift for a family member and was amazed by the sound from the speakers i was a little nervous with how cheap they were but the quality was amazing. Also phone we hooked up to it via blue tooth didnt have to be anywhere near the speakers we were able to put the phone at one end of the house and it was still connected at the other end of the house (easily 40+ft). In the end im very satisfied with the purchase of the product
The sound is AMAZING!! The unit is pretty small. Smaller than I thought it was going to be, but its perfect for mobility this way. The Bluetooth feature is great. The only weird thing is that the charger is USB only. It doesn't come with one for the wall. So, you have to use your computer or your phone charger unit. The battery last about 3-4 hours depending on how loud you have it and if you are using bluetooth or the sound cable.
I purchased this speaker for use at the beach. I've had it for about 8 months and it is GREAT! It has excellent sound quality, holds a decent charge and can withstand the stress of being bounced around in my beach bag.It uses a micro USB charger, so I just plug  it into my car on the way out to the beach for a quick charge and it goes for hours. The Bluetooth capability is very nice to have and the range is impressive.
The speaker crackles a lot. If I had it to do over again, I would not purchase. It also doesn't hold charge very long.
I used it for about a week now and it works, but definitely not loud enough. Disappointed because i have to purchase a different one now.
I bought this for my desk at work. The Bluetooth is a great feature. The sound quality is great. ++recommend
Answer: I think it's called a micro usb port also called a data port
