I have been using the Altec Lansing iM227 Orbit MP3 Speaker for awhile however I wanted something similar but with bluetooth - the Memorex MA3911MS did the job!

- Small size 2.4 x 3.9 x 2.5". This makes it a very portable mini-speaker and also convenient for traveling. I have posted some pictures to show the size compared to the popular Altec and the tiny Veho VSS-006-BT Portable 360 Wireless Bluetooth Speaker for iPhone/Phones/Laptops/Netbooks/Bluetooth Devices VSS-006-360BT
- I found the sound quality to be good but a bit flat out of the box. This is fine for movies, however for better quality sound adjust your devise equalizer and you wont regret your purchase.
- Controls are very easy to use. These are: volume up, volume down, answer phone, and mode (bluetooth/inline). Note that the speaker will revert its volume settings to medium level every time you turn it off/on. This can be a pain but I think it servers as a safety precaution.
- I like the fact it uses 4 AAA batteries. This is the main reason I got these speakers as I prefer having access to the battery case. I can get about 8 hours on my set of rechargeable batteries.
- Bluetooth frees you from tangled wires, however, there is an in-line connector if you need one for your non-bluetooth devices.
- There is a wall charger back-up if you run out batteries or want to save on battery costs.

- As mentioned above, the default sound is a bit flat out of the box but easily fixed with your devise equailzer.

Vine Customer Review of Free Product ( What's this? )
The Memorex MA3911MS Portable Wireless Bluetooth Speaker is small,( 2.4 x 3.9 x 2.5 inches) and very light, weighing in at less than one pound, which means it's a great wireless bluetooth speaker to take with you on a business trip. I would highly recommend this speaker if you are only going to use it to make telephone calls (it has an integrated microphone), or play podcasts. If you are going to use it to play music, however, you will likely be disappointed by the sound.
The speaker is very easy to set up. I was able to pair both my Android phone and Samsung MP3 player with no problem. It's powered by an AC adapter, or four AAA batteries. I would have prefered a rechargeable battery, as I don't want to have to carry additional AAA batteries when I'm not at home. It has a line-in connection, which is useful if you cannot connect wirelessly, but no wire to connect to the unit, so you have to provide that as well.
Now, on to the sound. The Memorex speaker produced a flat and somewhat muddled sound. Podcasts or the spoken voice sounds fine. Range-wise, the musical output is very limited. There are no controls to boost bass or treble, so you are left with a pretty unspectacular sounding bluetooth speaker, great for talk, and average or below average for music. With a list price of $50, I expected more.

I have tried numerous bluetooth speaker ranging from 15 to 200 in cost. I have decided to crown this as my favorite. Here are 4 aspects I have rated each one by.

Sound is very subjective when discussing speakers. This unit has very good sound quality. I saw some reviews knock the sound quality on this speaker, but im assuming they had to high of expectations for such a tiny speaker. At first I thought this was a single driver unit, but memorex has managed to stuff 2 small speakers in this tiny unit. I feel this benefits the sound versus the single speaker models out there. Trying to mix left and right channel sound into one speaker muddy's the sound some times. This unit has a very smooth sound, not shrill, and enough mid-bass to make out the bass lines in most songs without sounding like its strained to do so.

Build Quality-------
Memorex did a superb job making this unit. The materials feel solid and high quality. The buttons are easy to press and feel solid. The design is very minimalist but well thought out.

Bluetooth Connectivity------
This unit blew away so many other speakers I have tried on connectivity. In my line of sight test I was able to walk over 70 feet from my phone (a Galaxy S3) before the music became too choppy to listen. This range far exceeded every other speaker I tried. On phone calls this unit was middle of the road in voice clarity. Callers on the other end said I sounded good on their end, but could tell i was using a speakerphone device.

While not the smallest unit I tested, this was the smallest unit with stereo speaker drivers. This unit also was the only unit that was not rechargeable.

Not the strongest pair of speakers. Not as strong as what's available these days at 2 watts compared to the 3 you get with the single bt speaker you can find today but with two speakers I guess it gives better quality. I got this for the fact it's the only one around that uses replaceable aaa batteries which is a godsend for long trips on my bike. Just carry a bunch of aaa batteries with me. Again, a little light on the volume, so a little trouble in high traffic areas as I normally listen to talk programs but they work good for me.
