Question: How do i use with my smart phone.?
Document: The speaker has good tone and pretty good volume. However, it is not the easiest bluetooth devise to pare up with compatible smart phone or laptop. Took several times to work with my iphone and never did get it pared up to my mac book.
We work from home and use this primarily for conference calls. Pairs easily with our Blackberries & smart phones. Automatically reconnects when switched on. Sound clarity is excellent. Portable, simple and easy. We love it! !
If you're looking for an ultra-portable speaker for you're Ipad, smart phone or portable computer, this is what your looking for. The sound is crisp and maintains it's high quality sound when the volume is turned up. It doesn't matter if you play Beethoven or Pink Floyd. This is no cheap unit when it comes to quality. I haven't tried connecting the unit directly to whatever source I'm using because the Bluetooth works so well.
First of all it would have gotten 5 stars except I held 1 back because it seems that if you don't  have a really good smart phone, blue tooth operation is a little sketchy. Other than that the sound of this small device is surprisingly &#34;big&#34; and full. Totally worth the money I paid for it. Until I get a better phone I will run it with a cord from what ever source to the back of the unit. I would buy it again.
Very good product - great sound, battery life and range. I would recommend it to anyone that needs portable sound that the smart devices are incapable of.
Based on the price of this speaker, I had high hopes for it, but was very disappointed by the quality of the sound. It's not nearly as good asSatechi ST-66BTA Audio Cube Portable Bluetooth Speaker System for iPhone/Android Smart Phones/iPad/Tablets/Macbook/Notebooks, which is half the price of this, is more portable, and sounds much, much better.
works well. Don't use it that much anymore, could be a little bit louder. Not that much louder than my normal phone speakers
Bought this to use in My Wife's golf cart. Mounted it hanging from the roof. Excellent sound quality when used with her phone. Excellent buy for under $40.
It's SMALL footprint is a blessing. Like a little alarm clock. I have no experience with it's use as a speaker-phone but, it would likely perform well there too. BUY IT!
I bought this to use as a speaker phone for job site meetings, and it works extremely well. The speakers are loud with not distortion. It also sound good when playing music.
Answer: Turn the power switch on, then hold the side power button down. The light in front will turn blue first then a few seconds later it will flash alternating between blue and red. It should be able to pair via bluetooth at that time.
