The EPOS IMPACT 500 MS UC ANC WL USB-C+A is a professional stereo wireless headset developed for today's communication-intensive workplaces. Combining advanced noise management, intelligent microphone technology and flexible Bluetooth connectivity, it provides a dependable solution for office professionals, hybrid workers, contact centres and users who spend significant periods of their working day on calls and online meetings.
Featuring Hybrid Active Noise Cancellation, the IMPACT 500 helps minimise distracting environmental noise to create a more focused listening experience. This is complemented by EPOS AI™-based noise reduction and adaptive beamforming microphone technology, helping ensure speech remains clear even when working in challenging acoustic environments.
Unlike the dongle-free variant, this variant includes the EPOS BTD 900c Bluetooth USB-C dongle together with a BTD USB-C to USB-A adapter, providing flexible connectivity with compatible computers equipped with either USB-C or USB-A ports.
The IMPACT 500 uses a sophisticated six digital MEMS microphone system alongside adaptive beamforming and EPOS AI™-based environmental noise reduction. This combination is designed to distinguish the user's voice from surrounding workplace noise, helping deliver natural and intelligible conversations during calls and virtual meetings.
This makes the headset particularly well suited to open-plan offices, shared workspaces and hybrid working environments where surrounding conversations and general workplace noise can interfere with professional communications.
Hybrid Active Noise Cancellation combines feed-forward and feedback ANC technology to help reduce distracting surrounding noise. By monitoring sound both externally and internally, the headset creates a more controlled listening environment, helping users concentrate on conversations, meetings and focused tasks.
TalkThrough mode provides additional flexibility when interacting with colleagues, allowing surrounding voices to be heard without needing to remove the headset.
The IMPACT 500 incorporates EPOS BrainAdapt™ technology, developed to support concentration and reduce the listening effort associated with poor audio and distracting background noise.
Combined with advanced microphone technology and Hybrid ANC, BrainAdapt™ helps create a more comfortable communication experience for professionals who regularly spend extended periods participating in calls and online meetings.
The 1001490 variant includes the EPOS BTD 900c Bluetooth USB-C dongle, providing a dedicated Bluetooth connection for compatible computers. A BTD USB-C to USB-A adapter is also supplied, allowing the dongle to be connected to compatible computers equipped with a traditional USB-A port.
This is the key connectivity difference between 1001490 and 1001375: the 1001490 provides the BTD 900c dongle and its USB-A adapter as part of the package.
Bluetooth® 5.3 provides flexible wireless connectivity for professional working environments, while multi-point connectivity allows the headset to work across multiple compatible devices. The IMPACT 500 also supports native Bluetooth connectivity, giving users additional flexibility when moving between computer and mobile-based communications.
Designed to keep pace with demanding working schedules, the IMPACT 500 provides up to 36 hours of talk time. Fast charging also helps minimise downtime, with a short charge providing additional operating time when required.
The headset therefore provides the battery performance required for extended meetings, professional calls and collaboration throughout the working day.
The IMPACT 500 MS UC ANC WL USB-C+A is Microsoft Teams Certified and meets Microsoft's Open Office requirements, making it particularly suitable for organisations using Microsoft Teams as their primary communications and collaboration platform.
Weighing just 139g, the IMPACT 500 combines a lightweight stereo design with breathable leatherette ear cushions and a soft padded headband for comfortable professional use.
The on-ear design, flexible microphone boom and intuitive headset controls make it well suited to professionals who regularly spend extended periods on calls, virtual meetings and focused individual work.
