If your Valentine loves watching you make a fool out of yourself belting cheesy '80s tunes, consider turning your apartment into a romantic, private karaoke den. The portable VERKB mic, which connects to Bluetooth-enabled devices, has two built-in 6-watt speakers that provide 360-degree sound. It holds a 2600mAh charge—or enough for about 100 renditions of Love Shack. You can also record your performances for
blackmail fond memories. $40.
