BEENOS has introduced a limited edition pair of wireless earphones and a matching charger inspired by Shun Mizuno, the protagonist of Solo Leveling. The set is available through e-commerce sites integrated with Buyee, the company’s cross-border shopping platform. Orders close at 3:00 PM JST on 26 December 2025 and shipments are scheduled from late February to early March 2026.
The collaboration leans heavily into character design and voice work rather than offering a simple cosmetic refresh. Each unit includes newly recorded system voices by Shun Mizuno, created specifically to announce device status. This gives the accessory a more narrative feel, turning everyday audio prompts into character moments for fans.
The visual design also mirrors the series. The charging case and each earphone housing carry the Solo Leveling title and its key motifs. The wireless charger follows the same style, offering a matching look when used as a set.
Hardware tuned for everyday use
The collaboration is based on the CP-TWS01A, a true wireless model built on Qualcomm’s latest chip. It supports aptX Adaptive alongside SBC and AAC. This improves audio stability and reduces latency, especially for streaming or gaming. The earphones are also rated IPX7, making them suitable for workouts or commutes in wet conditions.
Battery performance remains one of the model’s selling points. Each earbud contains a 50mAh battery, and the charging case holds 400mAh, enough to fully recharge the earphones three times. Playback can reach up to nine hours at 80 per cent volume, although aptX use typically shortens this by 20 to 30 per cent. Charging takes about 1.5 hours for the earphones and about two hours for the case, which supports both USB-C and wireless charging.
The earphones are priced at ¥18,000 including tax. The matching wireless charger is priced at ¥4,400 and measures 102 by 102 by 7.2 millimetres with a weight of around 58 grams. It comes with a 100-centimetre USB-A to USB-C cable, though no power adapter is included.
