The Treblab HD55 speaker is designed as a rugged portable speaker for when you want to take your music on the go. Sure the speakers on some phones have come a long way, but some still don’t really sound much better than the transistor radios from long ago. Sometimes you just want to turn up the volume and enjoy your music on the go. Times like these it’s best to have a portable Bluetooth speaker, and the Treblab HD55 speaker wants to be that speaker.
