I actually won this speaker in a contest and am looking to get a second one since you can link the together for even more acoustics. These speakers are AWESOME, Ive used them for a party I had with 15+ people and it was loud enought to satisfy the need for music, almost everyone commented on it saying they couldnt believe how small it was and the great sound that came out of it, you can twist the top of the speaker and it pops up making itself a little taller which produces a lot more bass, I only use it when its poped up and collapse it when im not using it. I just brought it to my sisters house earlier today and she loved it and couldnt stop talking about it and the many things she could use it for (sounds like i gotta get her one for her Birthday :) The bluetooth works great on it, its easy to pair! I used it today and was able to charge it and play music at the same time. You can also link multiple mircobeat speakers together, I havent tried it yet but Ive read that they have to be linked with the wire thats included with it (originally I thought that they could be linked through bluetooth, but i think that is not the case, Im gonna try it when i get my second one). Well to sum it up... Great Speaker, Great Sound, Its Loud, Looks Nice, Great Compact Size, Great Battery life (used it many many hours throughout the day yesterday) I have been completely satisfied with this speaker and am buying a second one! I acutally have nothing negative to say at all about this speaker! I highly recommended it!!!!

In the last year I have tested a lot of small bluetooth speakers, Grandmax falls solidly in the middle of the pack. It has good mid-tone and acceptable although not great bass.

I am attaching a video which has several short snippets of music to demonstrate the speaker's sound. As one of the top reviewers I get asked to test and review a fairly large number of speakers. This allows me to compare a large number of speakers to each other. To help me make this comparison I always use the same two pieces of music, so I can compare speakers using "apples-to-apples" comparison. As a stress test for the bass I use Bach's Toccata and Fugue in D minor. The second piece of music (Tchaikovsky) does not have a lot bass and allows me to test the mid-range. Grandmax speaker did well on the mid-tone test, it had a bit of extra vibration at the bass range, but it did better than a number of other small speaker that could not handle Toccata's bass at all.

In the video I switch between the tablet's built-in speaker and Grandmax speaker so you can compare the sound. You can hear that the speaker produce the sound that is richer, fuller, and louder sound the the built-in speaker.

Grandmax speaker is 2 1/8" tall when extended, and can be collapsed into a 1 3.8" tall disk when not in use. It weighs in at 3.1 oz. Its small size makes a perfect travel companion. The speaker comes with a plastic suction cup base, which attaches to the speaker with a magnet.

The speaker comes with split flat cable which is 26 inches. The split cable sections (USB /AUDIO) are only 1 inch long. The cable gives you an option to use bluetooth connection or the audio cable. You can also use the audio cable to connect multiple speakers together.

Dont let the smaal box fool you, this speaker is the truth! The sound from this speaker fills the room and 2,3 + can be connected if desired. Great for playing music off youre phone that you havent had time to transfer to disc

Got this for Christmas. its great for listening to the radio in the morning in the shower when you phone speaker isn't loud enough. It came with a suction cup on the bottom for sticking it to a wall. It works really well and is really loud for how small it is. Id say it has the power of a normal TV speaker.. definitely enough to fill a room but its no surround sound. There are two things that would make this perfect. First, this may just be my phone, but even though the speaker is paired I have to actually go into the Bluetooth settings to connect to the speaker every time I use it. It doesn't just connect to your paired phone when you turn it on.. kind of annoying but I'm dealing with it. The other thing is the range is that great. My bathroom is 10 maybe 15 feet away from my nightstand where i leave my phone. The speaker cuts out if i try to leave my phone on the nightstand and use the speaker in the bathroom. Another annoying thing, but i deal with it. The main purpose for this was to listen to my radio talk show in the morning while i showered, and it does that great!

Just to be clear right off the bat.... NO BASS.

I have an iHome cheap $20 non bluetooth accordion style pop-up portable speaker (which my wifre blew out because she played music too loud and it doesn't have SRS to save itself from damage) that KILLS this on bass. I actually ordered this and another unit at the same time (iHome iDM8B Bluetooth Wireless Speaker...which DOES have SRS) to see which was better. The iHome was $50, this one $30. Anyway, the unit itself is attractive. Has a magnetic circle in the bottom which fits a suction cup that could go anywhere suction worked. Very cool. The switch on it goes from Off to USB (wired ausio) to BT. It can pay and charge simultaneously. So, as it is supposed to function, it does. But if you want loud sound that fills a room or anything remotely bassy. This is not it.
