Sennheiser Announces Major Enhancements to TeamConnect Bar Solutions
11 December 2025
Currently available for free download, firmware update 1.3.8 upgrades camera performance and security, among other features
Wedemark, Germany, December 2025 — Sennheiser, the first choice for advanced audio technology that makes collaboration and learning easier, has announced a firmware update that improves the already robust feature set of its TeamConnect (TC) Bar Solutions. Aimed to improve user experience, firmware update 1.3.8 includes camera enhancements, additional Dante audio outputs, increased network reliability and improved security and energy efficiency.
Sennheiser’s TC Bar Solutions are the most flexible all-in-one devices for small to mid-sized meeting rooms and collaboration spaces. The TC Bar S features four microphones and two speakers, while the TC Bar M features six microphones and four speakers. Both are certified for Microsoft Teams and include benefits like Trusted Sennheiser Audio Quality, easy setup, brand-agnostic integration, easy management and control, high video quality, security and sustainability.
With the latest firmware update, the TC Bar’s 4K AI-enhanced camera’s frame movement has been reduced, delivering a more natural, engaging, and lifelike video experience when using features like person tiling and auto-framing. In response to customer feedback, the new default camera mode will allow users to experience more consistent camera behavior during meetings, while making temporary in-call adjustments via remote possible.
TC Bars come standard with full-range stereo speakers for best-in-class audio performance. For users requiring a setup with additional audio outputs, the update enables connection of standalone speakers via Dante. Further, the external speakers can also be used to stream audio continuously to Sennheiser’s bi-directional communication solution, MobileConnect.
The firmware update will improve user experience in several other ways. To ensure meetings start without delays, the TC Bars’ standby wake-up times have been significantly reduced by optimizing the default energy mode and adding an optional “Always On” setting. The update also delivers peace of mind to users by ensuring that the TC Bars are compliant with all current security and regulatory standards. For complex environments, especially in split mode setups, network reliability has been improved through enhanced routing, ensuring an even more smooth and professional experience.
The latest firmware version is available for free and can be downloaded via Sennheiser Control Cockpit or by visiting the Sennheiser website and selecting TC Bar S or TC Bar M, scrolling down to the “Downloads” section and selecting “Firmware Updates”.
