Available for immediate purchase (^^) Thank you for viewing. This is a wireless earphone model featuring Sergeant Tsukishima (CV: Hidenari Ugaki) from the "Golden Kamuy × TOoKA BASE" collaboration. I used it for about a week and then stored it in a dark place. I once dropped an earphone on the ground, and sometimes there's noise in one ear, but there's no problem with use. It returns to normal when restarted. If you are concerned, please refrain from purchasing. I would be happy if those who love Golden Kamuy would consider it (⁎ᵕᴗᵕ⁎) *Accessories include the instruction manual and ear tips. *No claims and no returns are accepted. 【Product Specifications (Made by Gourmandise, Diamond Cut Model)】 ・Bluetooth version: 5.0 ・Playback frequency characteristics: 20~20000Hz ・Sound pressure sensitivity: 100dB±3dB ・Communication distance: up to 10m (when there are no obstacles) ・Supported profiles: HSP, HFP, A2DP, AVRCP ・Supported codecs: SBC, AAC ・Rated input: 5V/1000mA ・Music playback time: about 3.5 hours ・Talk time: about 3 hours ・Standby time: about 100 hours ・Power supply: microUSB 5V/1A ・Charging time: Earphones about 2 hours / Charging case about 2 hours ・Maximum playback time: about 12 hours (when the main unit and case are fully charged) ・Weight: 33g (including 4g x 2 for each earphone) ・Built-in power supply: Lithium-ion polymer secondary battery ・Accessories: Ear tips (S/M/L), instruction manual universal music Golden Kamuy Earphones Sergeant Tsukishima Hajime Tsukishima Tokushin Koito Lieutenant Koito Saichi Sugimoto Asirpa Hyakunosuke Ogata Type: Anime Name: Golden Kamuy Series: Seventh Division Character name 1: Hajime Tsukishima
