Review on Polk Audio BITB Boom Black by Rick Ross

I was looking for a small Bluetooth speaker that would allow me to listen to music without disturbing those around me. This device from Polk is the only Bluetooth speaker I know of that allows me to wear it on my clothing and hold it securely to my ear, meaning I can hear music clearly at half volume, which means that the battery lasts 4 hours of playback. the time recommended by Polk. It also extends the battery life on my iPhone, although I can turn the volume up to the max, but then the battery life of both devices drops significantly. Highly recommended portable bluetooth speaker!
