Thank you for viewing. This is a wireless headphone amplifier. The gain sound is very good. It also includes various effects, which is great for studying effects. Due to changes in my environment, I've been using an amp to produce sound more directly, so I'm selling this to organize my belongings. I hope guitar enthusiasts and those who practice frequently will take an interest. Price includes shipping. 【Brand and Model】 The BOSS WAZA-AIR is a wireless headphone system perfect for guitarists.
