Noise Cancellation Headphones for the iPhone 7
Apple released several wireless headphones to ship with the iPhone 7 including the Apple AirPods, BeatsX Earphones, Solo3 Wireless, and Powerbeats3 Wireless. One feature missing in all these are active noise cancelation. With the loss of the 3.5 mm audio jack, this means you'll need to start looking for alternative solutions for noise cancelation
So what are some of your options?
If you want to stay within the Beats world, Apple still offers the Studio Wireless (check here for pricing on Amazon) which still is based on pre-Apple design and technology, and doesn't use Apple's new W1 chip. This means you can't take advantage of the Class 1 Bluetooth range performance (100 meter) available on the Apple AirPods, BeatsX Earphones, Solo3 Wireless, and Powerbeats3 Wireless.
The Apple Store also offers the Bose QuietComfort 35 Wireless Headphones (check here for pricing on Amazon). Bose has a long history with noise cancelation technology and both Apple and Bose have probably spent a lot of time making sure the Bose QuietComfort 35 Wireless Headphones works well with the iPhone 7.
If you need a cheaper option and don't mind plugging your headphones into the iPhone 7's Lightning port, you can take advantage of the JBL Reflect (check here for pricing on Amazon) compact size and never needing to keep a battery charged. JBL was one of the first to announce a USB Type-C version Reflect Aware C but this product is still not available.
