    Love this speaker, it sounds great. I find it honestly better for movies/tv rather than music. However, when you combine two of them - which is quite easy with the UE app, you get great sound. Don't get me wrong I think it sounds great with just one but with two you really get a better experience.

    This item looks great, sounds amazing for the price and is comparable to the top competitor. I like the older model better simply because of the price difference but, the charging port on this new model is on the side instead of underneath.

    Not very loud and not much bass so after a week I returned. I ended up with the Sony XG500 which is more expensive but the Sony XG300 is also another good choice.

    My wife needed something to play music to a group of seniors where she teaches Bible study. My research narrowed the field and this was the top pick based on quality and price. As it turned out, she loved it. Happy wife, happy husband.

    Needed a solution to replace my wired outside speakers and am so glad we went to Bluetooth. Purchased 2 of these to pair together and now I can supply music for the whole neighborhood if I wanted to with great sound quality!!

    Great sound. Really like customizable emphasis on base / midrange / treble with app. Bought one for my son 1st (college sophomore) - he really likes it so bought one for myself. Loved the sale price on the concrete version!
