The Sony WH line includes all wireless Sony headphones. All these Sony WH headphones have different features. For example, some models have noise canceling to reduce ambient noise. This technology analyzes the environment via special microphones and bends it into an anti-noise. The anti-noise then ensures that you hear the original sound less well. This way, you hear more of your music and less of your surroundings. Do you want noise canceling headphones? Check out a model from the WH-1000X series, which have high-end noise canceling.
