This is a set including the Voicease (Voices) microphone, headphones, iRig, and cables – a soundproof room you can hold in one hand. Recommended for those who want to enjoy karaoke or podcasting with soundproofing. The iRig is included, so you can connect a professional microphone to your smartphone or PC. I received the complete set but haven't used it. I haven't even opened the box. It's worth approximately 40,000 yen. I believe it's new and unused. ▼ Set Contents / Reference Price ① Voicease Handheld Soundproof Room Amazon price: ¥28,000 ② Microphone CLASSIC PRO CM5/S ¥2,600 ③ behringer Closed-Back Studio Monitoring Professional Headphones HC2000 ¥3,200 ④ IK Multimedia iRig Pre 2 ¥10,500 ⑤ CLASSIC PRO / MIX030 Microphone Cable ¥700 Please note that I haven't confirmed the operation.
