If you don't want to keep on using the EarPods with Lightning Connector with your Apple iPhone 7, but also don't want to spend on Apple's new Apple AirPods, BeatsX Earphones, Solo3 Wireless, or Powerbeats3 Wireless, one low cost option is the Otium Wireless Sports Earbuds (click here for Amazon pricing).
The Otium Wireless Sports Earbuds, which tries to imitate the Beats PowerBeats2 Wireless, is a Class 2 Bluetooth device which allows it to be used with the iPhone 7 up to 10 meters. If you want to go 100 meters, you'll need to go with Class 1 Bluetooth Beats headphones as described in this review.
Still, the Apple iPhone 7 works fine with the Otium Wireless Sports Earbuds which is a very low cost option if you are looking for something that uses the Beats design styling.
