The Beats by Dre Solo Pro Noise-Canceling Over-Ear Headphones offer a couple of new features for the company. First, they charge using a Lightning cable. This helps it more easily integrate with your other Apple devices. On top of that, these full-size headphones offer active noise-cancelation technology. ANC means that these Beats headphones respond to your environment. These noise-canceling headphones can tell whether you’re at a loud event or in a quiet office just trying to focus. Likewise, they use real-time audio calibration to compensate for external noise. Additionally, these headphones ensure you’re still aware of your surroundings by allowing in some environmental sound. Finally, miraculously, these headphones can achieve up to 40 hours of battery life with the ANC and Transparency features turned off.
