Sony WH-CH520 offers a great user experience. These wireless (Bluetooth) headphones are able to work up to an exceptional 50 hours of battery life. Their price is low compared to other possible options. They appear to be able to charge fast and maintain charge for a long time. Their sound quality is good but nothing too exceptional. These headphones are lightweight and simple to handle. These headphones do have a built-in microphone, which delivers sound clearly, but can sound a bit unnaturally. It does have a good noise handling, but nothing exceptional. The main downside of this headphones is their noise canceling, or more correctly said it’s absence.
