With the Sony LinkBuds S Ocean Blue, you make an environmentally-friendly choice. Parts of the casing and charging case are made of resin from recycled plastic water dispensers. These compact fully wireless in-ear earbuds have noise canceling, which reduces ambient noise. So you can enjoy your music even in the most crowded spaces and don't have to turn up the volume unnecessarily. With the Sony Headphones Connect app, you can personalize the sound reproduction via an equalizer and listen to personalized sound. Does someone start talking to you while you're listening to music? The music pauses and the ambient noise amplifies when you start talking. Thanks to the Precise Voice Pickup technology, you'll always be clearly audible during phone calls. Activate the firmware update to use Multipoint connection. With this, you can connect 2 Bluetooth devices to the earbuds.
