The Cellz Bluetooth Portable Speaker is a great little Bluetooth speaker.

It is a rechargeable, mini USB chargeable, 3W digital power amplifier. It takes 2 hours to charge with a 3 hour music playback time. It is specified with Bluetooth v3 with support for AD2P and AVRCP.

The first thing that surprised me was after I turned the power on. It announced in a Japanese female voice “Bluetooth music play system turned on” and then “Bluetooth pairing successfully” . And really loud. Once of twice I started to play music to quickly after pairing and the sound kept breaking up. A quick power off and on solved this.

The speaker has music controls built on the bottom with the mic and call accept close by. It also has a line in input and micro USB card slot for playing mp3 songs on a micro USB card. In the box is the speaker, quick start guide , mini USB cable and 3.5mm to 3.5mm cable.

In use the 3W amplifier did sound rather loud and heavy a reasonable bass for its size. Taking a call on it was rather odd. You need to be 5-10cm from the speaker. It worked but it felt even stranger than using my Galaxy Gear to take a call on. Listening to podcasts was a joy on this little speaker. Clear and loud.

All in all though a very versatile nifty little Bluetooth speaker.

Rating 8.4/10.
