The yellow Sony WF-SP700N are wireless in-ear headphones designed to deliver customizable audio performance, extended listening time, and lifestyle convenience for athletes, music lovers, and audio aficionados exercising, traveling, or studying inside or outdoors. Their 6.1mm dynamic drivers utilize neodymium magnets and produce a wide frequency response of 20 Hz to 20 kHz, while a selectable bass boost function provides enhanced low-frequency reproduction. Bluetooth version 4.1 and NFC technology grant simple and effective wireless integration with your mobile device.

The built-in rechargeable battery affords up to three hours of listening time via a full charge or up to nine hours of playback via the supplied charging case. Activate the digital noise cancellation to keep your listening experience isolated from external noise or use the Ambient Sound Mode to stay aurally connected to the outside world.

Thanks to the integrated microphone and left and right buttons, you can take calls without accessing your smartphone. The IPX4 waterproof-rated design provides safe and stable operation even under heavy perspiration. The WF-SP700N headphones include arc supporters, multiple eartips, and a micro-USB charging cable.
