Sony WI C100 Wireless in Ear Bluetooth Headphones with Built Microphone, Black, WIC100/B, Small (Refurbished)

Packed with features: WI-C100 wireless in-ear headphones offer great value for money, with a wealth of features including long battery life, high-quality sound, splash-proof design, and compatibility with the Sony | Headphones Connect app. Long battery life of up to 25 hours: enjoy up to 25 hours of non-stop music. And when your headphones are low, you can charge 10 minutes of fast charge for up to 60 minutes of playback. Make your music sound more natural: When an original music source is compressed, it loses the high-frequency elements that add detail and richness to a song. Our Digital Sound Enhancement Engine (DSEE) faithfully restores them and produces high-quality sound that is closer to the original recording. Well-balanced tuning: Tuning is well balanced from low to high frequencies, and the vocals are natural and clear. So the WI-C100 headphones fit any music genre. Your sound, just the way you want it: Customize your sound to your personal preference. Choose from a variety of presets that match the music genre you're listening to, or create and save your own custom presets with the equalizer feature on the Sony | Headphones Connect app. Splashing and sweat, no problem: With an IPX4 water resistance rating, splashes and sweat won't stop these headphones so you can keep moving to the music. Stable wireless connectivity: Say goodbye to cable clutter - Bluetooth wireless technology allows you to connect wirelessly to your device and enjoy stable, uninterrupted listening. Clear hands-free call quality: the call flows freely with clear hands-free calls thanks to our high-quality built-in microphone. You don't even have to take your phone out of your pocket.
