Thank you for viewing. audio-technica HYBRID NOISE CANCELLING ATH-TWX9 ※Accessories are shown in the images after the second one. I have used it a few times since purchasing it. I am selling it now because I haven't used it much. There are few scratches, stains, or signs of use, and it is a very good condition item that can still be used. The operation is also fine, and it works normally. Operation has been confirmed. I will clean it before shipping, although it will be a simple cleaning. This is a used item, so please understand that the appearance and feel of use may vary from person to person. Only those who understand that it is a used item should purchase it. ◆Product Details◆ Wireless Earphones ATH-TWX9 Brand: Audio-Technica Wearing style: Separate left and right, completely independent Earphone/Headphone type: Canal type Color: Black Wireless/Wired connection: Wireless Earphone/Headphone functions: Noise canceling, Microphone, External sound capture, Automatic power-on function, Waterproof, splash-proof, Remote control Low-frequency range (Hz): 10.0 Hz High-frequency range (kHz): 40.0 kHz Impedance (Ω): 16.0 Ω Sound pressure sensitivity (db): 102.0 db Wireless standard: Bluetooth Bluetooth codec: aptX AAC SBC IP standard (waterproof standard): IPX4 Drive method: Dynamic type Driver size (mm): 5.8 mm Charging terminal: USB Type-C Qi standard Charging time: 2.5 hours Weight (g): 10.8 g
