Thank you for viewing. This is the BOSS WAZA-AIR, a completely wireless headphone amplifier convenient for guitar practice at home. I purchased it from Soundhouse in January 2021. I bought it for use at night, but I mainly use an amplifier, and I only used it about 5 or 6 times after purchase. After that, it was left in a drawer. There are no noticeable scratches or rust, and I think it is a beautiful item in good condition. There is no stickiness or cracking on the ear pads. I tested the sound before listing it, and there were no problems. Please refer to the following URL for product details: https://www.boss.info/jp/products/waza-air/features/ [Contents] Everything in the photos is included. • WAZA-AIR main unit • Transmitter (WL-T) • Micro USB charging cable [Other] I will wrap it in bubble wrap and ship it in a cardboard box. Please refrain from purchasing if you are nervous or seeking perfection. This is a used item, so please check the photos carefully and consider purchasing only if you understand the condition.
