Honkai: Star Rail Robin Collaboration Model Earphones with Case

Order via Japan Rabbit

Step into Penacony with the official MOONDROP x Honkai: Star Rail Robin Collaboration Earphones. Audio specialist MOONDROP has teamed up with the popular space-fantasy RPG to capture the elegance of the galaxy-renowned singer Robin, right down to the sound in your ears. This Japanese edition includes exclusive voice prompts recorded by Robin herself, greeting you whenever you power on, power off, or switch between music and game modes.

Built for high-fidelity listening, these earbuds use a hybrid driver system: a 10mm dynamic driver with a TiN ceramic-coated diaphragm, CCAW voice coil, and N52 neodymium magnet, paired with a 6mm planar magnetic tweeter for crisp, detailed highs. The universal in-ear monitor shell is made from medical-grade, 3D-printed resin, developed in partnership with 3D-printing specialist HeyGears for a precise, comfortable fit. Its finish shifts color with the light, echoing the shimmer of Robin's stage costume.

Under the hood, MOONDROP has packed in serious tech: Bluetooth 5.4, LDAC and LC3 codec support for low-distortion, low-latency audio, active noise cancellation layered with passive isolation from the ergonomic shell design, and an ENC dual-microphone array with beamforming for clearer calls. An ambient sound mode lets you stay aware of your surroundings without taking the earbuds out, while optical in-ear detection automatically pauses playback when you remove one earpiece and switches the other to ambient mode. Multipoint connection keeps you linked to two devices at once, and the MOONDROP app lets you fine-tune touch controls, noise cancellation, and choose from five sound tuning profiles.

Battery life reaches up to 9 hours on the earbuds alone, or up to 39 hours total with the charging case, which supports both USB Type-C fast charging and wireless charging.

This is a brand-new, unused set, complete with the leather case, a Robin-design acrylic plate, and ear tips: a fitting tribute to Penacony's stellar diva, ready to soundtrack your own concert, start.
