These Unicorn Gundam earbuds from STUMPE (Elephant Trunk) are as much a collectible as they are audio gear. The charging case is modeled on the left shoulder armor of the RX-0 from Mobile Suit Gundam Unicorn, in faceted white with Anaheim Electronics and RX-0 markings, and the outer box carries the © Sotsu Sunrise license mark. For Gundam merch collectors, the case is the main attraction.
It moves like the suit in the series too. You can manually transform the armor between its Unicorn and Destroy modes, and a red-orange light runs through the seams, while the lid hinges up to reveal the earbuds inside. The whole thing packs into a black hexagonal Laplace's Box, with panels printed Charter of the Universal Century and Anaheim Electronics, and a hexagonal tray that holds the case for display.
The white in-ear earbuds have silicone tips and RX-0 printing. They connect over Bluetooth 5.0 with SBC and AAC audio at a range of 10 meters, with a 20 Hz to 20 kHz response. Music time reaches 26 hours, standby lasts 50 hours and charging takes about 1.5 hours through the USB Type-C port on the armor.
