Tsutaya has begun selling two limited-edition models (500 units each) in collaboration with American headphone manufacturer Skullcandy and SPICY CHOCOLATE, the hit song behind NTT Docomo's "Tsunagu Omoi wo Tsunagu" commercial (now airing) and "Zutto feat. HAN-KUN & TEE." Available at approximately 100 stores nationwide, the two limited-edition models are the "CRUSHER Realtree" (¥14,800) and the "HESH 2 Realtree" (¥8,600). Both models feature the Realtree brand's signature camouflage pattern, featuring realistic tree and forest motifs. The "CRUSHER Realtree" features a dual driver system that allows users to adjust the bass volume to suit their music. The headphones deliver high-quality, deep bass. The "Hesh to Realtree" model features a textile headband and earth tones throughout. The two limited edition models will be available to listen to in-store along with songs from SPICY CHOCOLATE's greatest hits album.
