Sony Ericsson has been dishing out portable speakers for almost all it’s mid range music phones for quite a while now. Not to left behind, Nokia ups the ante and has come out with the MD-8 mini portable speakers. Unlike the Sony Ericsson speakers which need to be plugged into the Walkman phones, Nokia’s MD-8 Mini speakers feature built-in rechargeable batteries to make sure that your phone’s battery doesn’t get drained out. Designed in a smart looking flip-open design, these portable speakers are small enough to be carried around in your pocket almost anywhere. And in true Nokia tradition, these speakers will belt out an awesome forty hours of non stop music on a single charge. If you get tired of listening to MP3 music from your phone, you could also tune in some FM Radio as this little wonder has a built in FM reciever. Nokia’s MD-8 portable speakers will hit stores in the latter half of the year.
