I bought these speakers for my daughter who wanted to make love "really Party" in her room. The right box was already broken after two days, but the sound so amazing that I decided to send them back and again to order. Although Amazon at the time 3 weeks delivery time auswies! It's been almost four months and all is well. The music from the phone sounds almost like in a live disco, really loud and with incredible pressure. We are excited! Positive to mention is the fact that very many other BT speakers have a clearly audible "natural hum" when the music is low or off. Not so the Samson MediaOne BT4, hum no trace! Long story short: strong buy recommendation on my part.
