The good news is that at CES 2018, Sony has unveiled a trio of wireless in-ear headphones that ranges in price points, meaning that you should be able to find a pair that suits your budget. However if there is a feature that they all share, it is that they have an IPX4 rating, meaning that they are essentially sweat-resistant.
Starting with the WF-SP700N, these are a pair of “true” wireless earbuds, where they are completely devoid of any wires, so if you like wireless earbud concepts like the AirPods, then the WF-S700N might be for you. They are also the sports equivalent of last year’s WF-1000X, offer up to 3 hours on a single charge with a case that charges it two times more, and is priced at $180.
For those who prefer having a cable/wire, there is also the WI-SP600N that offers noise-cancelling technology and a battery life rated at 6 hours. It is priced at $150. Last but not least is the WI-SP500 which ditches noise-cancelling technology which in turn boosts its battery life to about 8 hours and is also the cheapest at $80.
