Mission 615 Monaural USB Headset

The Poly Mission 615 is a single-ear wired headset built for professionals who need to stay aware of their surroundings while on calls. It connects via USB and includes a Type-C to Type-A adapter for broad device compatibility. The lightweight design and included carrying case support mobile workers and office-based users alike. It is not for users who require stereo audio or dual-ear coverage for immersive sound.

USB Type-C with Type-A adapter

The decisive specification is the USB connection paired with a Type-C to Type-A adapter included in the box. This allows the headset to plug directly into modern laptops with USB-C ports and older systems with standard USB-A ports without extra dongles. Buyers whose devices lack USB ports entirely cannot use this headset.

Monaural coverage for call clarity

The single-ear design keeps one ear open to ambient sound, which suits open-plan offices and hybrid environments where situational awareness matters. It handles voice calls and online meetings comfortably for extended periods. It runs out when the task demands stereo separation, spatial audio or passive noise isolation across both ears.
