Bluetooth headphones specifically for sleeping. They are in excellent, like-new condition, used only about 3 times. The sound is excellent and comfortable, especially for sleeping, and they can also be used during the day. Fast shipping, and they come with their Type-C (USB-C) charger. To clarify: The microphone works, but its quality is average and it's not primarily designed for calls. Reason for selling: The headphones are a bit too big for me and didn't fit well. Selling for offers.
