I've used these a few times, but they didn't fit, so I've been storing them. I'm selling them now to organize my headphones. As far as I could tell, there were no issues with the wiring or sound output. I will ship them in the original box, which will be placed in a cardboard box with cushioning material. I will clean them with alcohol before shipping. ■ This item will be shipped anonymously with free shipping. ■ No comments are needed before purchase. ■ Please note that I will not respond to price negotiations. --- 【Specifications】 Type: Open-air dynamic Driver: φ53mm Sound pressure level: 100dB/mW Frequency response: 5～30000Hz Maximum input: 700mW (JEITA) Impedance: 38Ω Plug: φ6.3mm standard / φ3.5mm mini Gold-plated stereo 2-way cord length: 3.0m (single-sided) Weight: 265g (excluding cord) 【Features】 ◆ Reproduces beautiful mid-high frequencies with a high-input CCAW voice coil φ53mm driver.
