Forever GHS-700 BT Wireless Headset with Microhpone on-ear

Put on the headphones and cut yourself off from the irritating noises outside. ANC technology - active noise cancellation - reflects unwanted sounds, making them inaudible to the human ear. Enjoy distraction-free audio entertainment or relaxing silence. The ANC function can also be turned on without turning on headset. The long-lasting battery of the BTH-700 Bluetooth in-ear headphones allows the device to work for up to 11 hours. An adjustable silicone headband and comfortable earcups ensure comfortable wearing. The headphones fold in two directions - inward and flat - making them easier to store and carry. Intuitive buttons guarantee convenient and efficient control of the device. The built-in microphone allows you to make phone calls. Answer and end a call from the headphone panel, no need to take out the phone.
