There are no operational issues, but please understand that this is a used item and may have minor scratches and signs of use before purchasing. All accessories are shown in the photos. The M-size ear tips that were attached at the time of purchase were the correct size for me, so the other sizes are unused. I will clean and include the M-size ear tips, but please consider them as replaceable. 〜・〜・〜・〜・〜・〜・〜・〜・〜・〜・〜・〜 Wireless Noise Canceling Stereo Headset WF-1000XM5 (B) Black Brand: SONY Wearing style: Separate left and right, completely independent Headphone type: Canal type Structure: Sealed Color: Black Wireless/Wired connection: Wireless Headphone features: Noise canceling, Hi-Res, Microphone, Ambient sound mode, Sound quality adjustment, Waterproof, Splashproof, Remote control Low-frequency range (Hz): 20 Hz High-frequency range (kHz): 40 kHz Wireless standard: Bluetooth Bluetooth codecs: LDAC, AAC, SBC IP rating (waterproof rating): IPX4 Driving method: Dynamic type Driver size (mm): 8.4 mm Charging port: USB Weight (g): 11.8 g
