The test device works either via Bluetooth 4.1 or wired. The supplied single-sided cable has a smaller plug on the hand side and offers a one-button remote control with an integrated microphone. Exemplary: The E650BT can not only work passively in cable operation, but also use active noise canceling. The switch for wireless operation is located on the right auricle. There are also switches for pairing and noise canceling. A three-button controls the functions start, stop, answering calls, volume control, track skipping and calling up voice control in the smartphone. In cable mode, the button enables call processing, starting and stopping the music and jumping between tracks. In practice, the Bluetooth connection is stable and has a sufficient range, for example for use with a television. Practical in this context: The E650BT can switch between two Bluetooth sources and thus switch a call to the handset during movie playback. The powerful Li-Ion battery provides an operating time of 15 to 30 hours after two to three hours of charging, depending on the use of Bluetooth and noise canceling.
