Dark gray FW3 wireless earphones with charging case, with left/right indicators. I purchased these new and used them for about 3 months. The sound quality was excellent. However, I've switched to a different pair with noise-canceling features, so I'm selling these. They show signs of use, but there is no significant damage to the main unit. The replacement ear tips and charging cable are unused. The instruction manual and box are also included. Please note that the box has a slight tear as shown in the photos. 【Product Details】 Brand: FiiO Wearing Style: Separate left and right, completely independent Earphone/Headphone Type: Canal type Color: Gray系 (Gray-toned) Wireless/Wired Connectivity: Wireless Earphone/Headphone Features: Microphone, Sound quality adjustment, Waterproof/Splashproof, Remote control Low-Frequency Response (Hz): 20.0 Hz High-Frequency Response (kHz): 20.0 kHz Impedance (Ω): 32.0 Ω Sensitivity (dB): 106.0 dB Wireless Standard: Bluetooth Bluetooth Codec: LDAC, aptX, AAC, SBC IP Rating (Waterproof Rating): IPX4 Driver Type: Dynamic Driver Size (mm): 10.0 mm Charging Port: USB Type-C Charging Time: 1.66 hours Weight (g): 12.0 g Thank you for viewing.
