All HTC One phones have Beats Audio built in. Beats Audio automatically turns on when you play music, but you can opt to turn it off. I could definitely hear a positive change in music quality, especially with rock and metal music, when Beats was running. Bass sounded richer and the vocals fuller. Beats Audio also kicks in when you play a YouTube video.

Unlike the One phones, the Evo has a microSD slot so you can expand your phone's memory beyond the built-in 16GB, with photos, video, apps, and so on.

The phone also comes with HTC Watch, which is the company's movie-streaming service. If you wish to stream movies off your phone, however, I'd go with Netflix, as it has a larger library than Watch.
