How about true wireless earbuds that double as a functional Bluetooth speaker? Meet the Duolink SpeakerBuds. You can either enjoy your favorite tunes with the earbuds or place them into the speakers for high quality stereo sound. It only takes 2-hours for a full charge, or extend its battery life up to 6-hours by slotting them into the speaker / charging case. Best of all, you can still charge the earbuds while playing music by putting them into the speakers.
