Sony WI-C400 Wireless Earbuds Bluetooth-Enabled, Black

Long Battery Life of Up to 20 Hours With up to 20 hours of continuous music playback on a single charge, you won’t have to worry about running out of battery power during long trips or outings.

Comfortable neckband design It fits comfortably around your neck, so you can keep it draped there when not in use. It features “cable management” that lets you adjust the cable length, allowing you to neatly store the earbuds.

Convenient vibration alerts for incoming calls When you receive a call on your smartphone, the neckband vibrates to notify you. You won’t miss important calls even when you’re focused on your music.

Easy Control at Your Neck & Hands-Free Calling With the buttons on the neckband, you can play/pause tracks, adjust the volume, and launch your smartphone’s voice assistant (Siri/Google Assistant) with a single touch.

High-Quality AAC Codec Support Compatible with the AAC codec, which enables high-quality playback on devices like the iPhone, so you can enjoy clear mid-to-high frequencies and powerful bass.
