Wireless earbuds Lenovo T40 connect to any device that has bluetooth. They feature Active Noise Cancellation (ANC) which blocks external noise in environments such as Mass Transit, so you can better listen to your music or calls. They come with a carrying and charging case for the earbuds.

Bluetooth headphones have many benefits for their users, including the following:

1. Freedom of movement: You can move freely without having to hold your phone in your hand, allowing you to work, exercise, and engage in other activities or even drive while on a call.

2. Ease of use: Connecting Bluetooth headphones to your device is very simple and quick. Simply enable Bluetooth on your device and connect your headphones. Additionally, most Bluetooth headphones have control buttons on the headphone itself, allowing the user to control their music or answer calls without having to touch their device.

3. Time-saving: With Bluetooth handsfree, you can perform multiple activities without having to interrupt your call, allowing you to be more productive.

4. Long battery life: Bluetooth headphones usually have a built-in battery, which can provide up to several hours of continuous use with just one charge. This means you don't have to worry about having to charge your headphones frequently.
