A:Answer Hi Jack, Thanks for your inquiry. This unit has a Bluetooth Specification version 4.2. If you ever experience a delay, or if the sound skips, please follow the guidelines below:
• The receiver and the BLUETOOTH device are too far apart.
• If there are obstructions between the receiver and your BLUETOOTH device, remove these or move the receiver and/or device avoid them.
• If there is a device that generates electromagnetic radiation, such as a wireless LAN, other BLUETOOTH device, or a microwave oven nearby, move it away.
Regards,
Sam
