Summary: Considering that I am using this unit in a large room, and the sound is quite good. I connect using Samsung S4 from about 30 feet away (unobstructed) and the connection is perfectly reliable. I am not crazy about the interface, which is just volume and power, but it works.
Summary: It's a good, convenient battery-powered speaker. Yes, it has an AC adapter, but it's easy to carry around the house if you use batteries. Lately, though, it seems to have forgotten how to turn off. You have to pull a battery out. Stupid, huh? Except for that, works well.
Summary: I have three kids, and one of them got this for Christmas a few months ago, and now my other two kids each bought one because they liked the other's so much. Sound quality is great and has a decent range.
Summary: Speaker works great with my iPhone 6 but won't keep a connection with my MacBook. MacBook doesn't have a problem connecting to other bluetooth speakers I own. Speaker sound is good and loud but its inability to connect with my MacBook is a problem.
Great Sounding Affordable Bluetooth Speaker NOT 18 Watts RMS. 3W + 3W RMS
8 July 2014
Summary: I purchased this from the Lenovo website and just received it today. This is NOT 18W RMS. It has two speakers each rated at 3W RMS as stated in the user manual. Unless someone opens their unit and gets the read out from the speakers themselves it will stay at that.
Summary: It frequently bends the pitch up or down and can change the key by an entire half step at times. I am classically trained in multiple instruments, so I may simply be particularly sensitive to this. Most people might not have this problem depending on what the speakers are being used for.
Summary: I'm surprised at all the good reviews. As a Bluetooth device it works great. As a speaker it sounds like cheap PC speakers sound. My daughter gets a better sound out the built it speakers of her Macbook Pro.
