We paired the Aura Blu Note with the Samsung Trance, which has stereo Bluetooth. After we connected the two devices, the second we hit play in the Trance's music player, the Blu Note streamed its songs. Music quality was pretty good, and the stereo widening and bass boost do a good job in making the songs sound richer and fuller. The stereo widening creates a three-dimensional sound and the bass boost provides a deeper bass. However, it wasn't terribly remarkable, as songs still had a slightly hollow quality when compared with a full-fledged high-fidelity speaker. Still, for a portable speaker, the sound quality is quite good.
The Blu Note also has decent call quality. Callers could hear us loud and clear even though we were on speakerphone. You do need to speak relatively close to the speaker, though, about a couple feet or so. On our end, we could hear our callers clearly as well with hardly any static or background noise. When a call comes in you will hear a beep or tone, and if music is playing, the player will pause automatically. Aside from that, the Blu Note doesn't have a lot of phone features. It can answer, end, and reject calls, but that's about it.
You can store up to eight Bluetooth profiles, so you can pair it with multiple devices. It has an approximate battery life of up to 10 hours with four AA batteries.
