Here is a great sounding JBL bluetooth speaker in blue.

Serial Number -TL0416-DJ0698169

The JBL Flip 4 puts out powerful sound but takes up little space on your desk or in your room. This portable speaker system's bright blue color is as vibrant as its audio clarity. With an integrated microphone, the Bluetooth speaker is even good for conference calls. You can link the wireless system to other JBL Connect+ enabled speakers for an amplified output. Since this model is waterproof, you can take the Flip 4 with you in all sorts of weather.
