August EP640 Bluetooth v4.0 NFC headphones - Wireless Stereo Headset Speakerphone, built-in microphone, 3.5mm audio input and battery - with leather ear pads (Black) (Wireless Phone Accessory)
After my four pairs of headphones have died from cable break in a month, I decided to try out Bluetooth models. After some search, I came across the EP640 August and was not disappointed. However, it should be clear that the headphones for + -40 are.
