This section describes specific known limitations in the Cisco Headset 730.

Connection with iPhones over a USB-C to Lightning Cable Adapter

• There is no audio in the headset when it's connected to an iPhone via a USB to lightning cable adapter.

  Use Bluetooth to connect your Cisco Headset 730 to a mobile device. Cisco only claims support for the cables and accessories included with your headset.

Choppy Audio Over the USB-C Cable with the MacBook Air

• On a MacBook Air with macOS Mojave 10.14.5, music playback becomes choppy for a few seconds after a Cisco Headset 730 connects with the USB cable.

  To avoid this issue, pause any streaming music or audio before the headset connects with the USB cable.

Windows 10 Crashes After Waking Up from Sleep Mode with Webex Teams Open

• Microsoft is aware of an incompatibility when turning the Cisco Headset 730 on or off on a Windows 10, version 1803 (or later) machine after the OS resumes from sleep or hibernate. Users may encounter a blue or black screen due to a bugcheck (error code 0x139). Microsoft has released a fix for this issue (see KB4541333).

Lost Call Control on Legacy HP Laptops over Bluetooth

• Older HP Laptops that run the Realtek Bluetooth 4.0 Adapter driver have trouble maintaining a stable Bluetooth connection with the Cisco Headset 730. The Bluetooth pairing frequency often alternates between Music and Voice which disables the headset Bluetooth call control functionality.

  You can use the included USB Adapter to connect to older Windows 10 devices that don't support the Cisco Headset 730.

Headset Can't Switch Sources from MacBook Laptop

• On the MacBook Pro with MacOS Mojave version 10.14.5, music playback can't switch the Cisco Headset 730 from the MacBook Pro to a different Bluetooth source.

  You can only change the Cisco Headset 730 Bluetooth source from a MacBook Pro running MacOS 10.14.5 in the following scenarios:

  • Make or answer a call on a different Bluetooth device.

  • The Cisco Headset 730 connects to your MacBook Pro via the USB cable.

  • The Cisco Headset 730 connects to your MacBook Pro via the USB Adapter.

The Cisco Headsets App Doesn't Cleanly Disconnect the Cisco Headset 730 from Windows 10

• When you use the Cisco Headsets app to disconnect your Cisco Headset 730 from Windows 10, the list of connected devices occasionally still lists your headset and attempts to reconnect. You can directly disconnect your headset through the Windows 10 device page.

Music Controls Get Lost on Windows 10

• The Cisco Headset 730 occasionally loses music playback control on Windows 10 devices. This problem only occurs over a Bluetooth connection. The volume controls are unaffected by this limitation.

Audio Delays on Calls with the USB Adapter

• Turn off your Cisco Headset 730 before you plug in the USB Adapter.

  When you make a call with the USB Adapter, there is a 5 to 15 second delay while the headset speaker and microphone connect to the call. This problem only appears when the Cisco Headset 730 is already on when the USB Adapter plugs into a call device and pairs.

Poor Audio Through the 3.5 mm Cable

• The included 3.5 mm cable does not always cleanly connect to the Cisco Headset 730. If you experience little or no audio with the 3.5 mm cable, disconnect and reconnect the cable.

MacBook Air Uses Internal Speakers When USB Adapter Connects

• Intermittently, a MacBook Air running MacOS version 10.14.6 doesn't automatically switch the audio source when the Cisco Headset 730 USB Adapter connects. You can still manually select the USB Adapter through your system preferences.

  Select Apple menu > System Preferences > Sound > Output > Cisco HS USB Adapter.

Cisco Headsets App Triggers Incorrect Audio Prompt

• When you connect to the Cisco Headsets app with two active Bluetooth connections, the headset incorrectly states that it can't connect with any other devices.

  The Cisco Headsets app can connect to the headset even when there are already two active Bluetooth connections. Slide up and let go of the Power/Bluetooth Slider to connect the headset to the Cisco Headsets app without putting the headset into pairing mode.

You can get an advanced look at some of the upcoming features when you turn on the Beta Test feature in the Cisco Headsets app. While we're offering a sneak peek at some of our upcoming features, keep in mind that beta releases are unfinished and may contain open issues.
