I originally looked at the typical portable bluetooth speakers with lithium batteries. After listening to several, I was very disappointed by the sound quality, even for the speakers that were getting really good reviews. Because this Marshall Stanmore was in the same area of the store, I listened to it and found it to be far superior. The Stanmore has bass and treble controls to allow you to tweak the sound to your liking, something that is missing on most other small speakers. It also gets fairly loud for being so small. It terms of sound quality and volume, it will blow away the competition. While this speaker is portable and not that heavy, it is not small enough to put in a purse, and it does not come with a carrying strap. It also does not have a lithium battery, so it needs to be plugged in to be used. Having a lithium battery allows use away from an outlet, but the battery will one day fail, and most portable bluetooth speakers do not have a lithium battery that can be replaced, or easily replaced. So, when it fails, you will need to replace the speaker for most models. Also, lithium batteries need to charged and depleted periodically to maintain them. In any case, if you want something for the beach, the Stanmore is not what you want because it does not have a battery and is not waterproof. But if you want something for a lake house of ski cabin and you are driving there, the Stanmore is perfect. In terms of bulld quality, the Stanmore is very solid and high quality, way better than most portable bluetooth speakers. The Stanmore is between the Marshall Kilburn and Woburn in terms of size and sound quality (the Kilburn is the smaller, and I think it comes with a lithium battery that can be replaced). The sound quality of the Kilburn was less than I was looking for, and the Woburn was too large, which is how I ended up selecting the Stanmore. Marshall has some other small speakers for home use, but I have not seen them. In summary, I found the Stanmore to be small, but provide great sound for the size. I preferred the fact that it did not have a battery for my planned uses.
