MiiKey’s Rhythm headphones free you from cords with two forms of wireless connectivity. Near-field communication lets you tap and connect to two NFC-enabled devices at once, such as a tablet and smartphone, without having to interchange the pairing. You can also wirelessly stream music via Bluetooth. No matter which way you connect, the headphones deliver high-definition experience with four-channel stereo sound. Noise cancellation maintains this superb audio by blocking out distractions such as ambulance sirens and the gaping vacuum of black holes. Further conveniences include a built-in microphone for hands-free calls, Smart Talk with Siri, and an audio cable for wired use.
