    This is a great product and sounds great! I have purchased two for myself and connected them in series for a larger sound outdoors as well as consistent sound throughout our whole house. I have purchased two as gifts for family members and one as a gift for a high school music department chair. Everyone loves them and agree the sound quality is remarkable!

    I heard this and the Sonos in store for years before deciding to purchase. Earlier models seem to have more volume and bass. Volume when plugged into ac power not bad.

    Very good sound quality and ease of use. It wasn’t as loud as I thought and I returned it because I needed something more powerful but if you don’t need to get too loud this is definitely a good speaker.
