I was looking for a small speaker that I can take to work to use with my phone, and had not found anything I like yet. Then I was looking on the bose site and found this one. I love it, you can take it on bike rides with you, the office. Anywhere you go. Holds a good charge. Sounds fantastic. I already own a Soundlink Mini speaker that plugs in, it is a wonderful speaker also. I love Bose products. They know how to give you a product that works great and sounds great!
