The Jabra Engage 45 SE Mono Wireless Headset Bundle Answering a desk phone call usually means being at your desk when it rings — until you add remote call control. The Jabra Engage 45 SE Mono wireless headset bundle pairs this DECT headset with the exact remote-answer accessory your desk phone needs, so you can accept or end a call from up to 490 feet away without touching the handset at all. It's also built with a level of call encryption most office headsets don't bother with. FIPS military-grade 256-bit encryption goes beyond standard DECT Security Step C, which matters if your calls involve anything you'd rather not have intercepted over the air. Build the exact Jabra Engage 45 SE Mono bundle you need One choice here: which remote-answer accessory matches your desk phone. The headset itself is identical across every option — only the bundled adapter or lifter changes. [icon:ms-teams] Avaya EHS.

A universal option that works with the vast majority of desk phones rather than requiring EHS certification for a specific model — the pick if your phone isn't on any EHS-certified list above. [callout type="honest"]EHS certification is phone-model specific — an Avaya EHS cable won't work on a Cisco phone, and vice versa. If you're not certain your exact desk phone model is on the list for the accessory you're considering, the GN1000 lifter is the safer universal choice.[/callout] Wireless range and battery on the Jabra Engage 45 SE Mono The Jabra Engage 45 SE Mono covers up to 490 feet from the desk phone on DECT wireless — enough to step away to a filing cabinet, help someone at the front desk, or take a call into the next room without dropping the connection. A full charge delivers up to 13 hours of talk time, and the battery reaches roughly 40% in 30 minutes and 80% in 60 — useful if you only have a short break to top up before the next shift. [stat]Up to 490 ft DECT range · Up to 13 hrs talk time · FIPS 256-bit encryption[/stat] Built for shared desks and busy floors The headset supports hot-desking, so it's easy to move between workstations without a lengthy re-pairing process, and Jabra's DECT technology is designed to handle up to 120 headsets operating in the same office without interference — a real consideration if you're outfitting a full floor rather than a single desk. Call quality and hearing protection A dual-microphone setup with wideband audio is tuned for speech clarity, and Jabra SafeTone 2.0 combines PeakStop sound-spike protection with speech normalization to keep volume consistent and safe across a full day of calls. A built-in busylight signals your call status to anyone walking by, cutting down on the "are you free?" interruptions mid-call. [callout type="tip"]The Engage 45 SE Mono's battery is user-replaceable — worth knowing if you're planning to keep a headset in service for several years rather than replacing the whole unit when battery capacity eventually drops.[/callout] For a desk phone user who needs to step away from their desk without missing a call, this bundle gets you the exact remote-answer hardware your phone needs from the first day it arrives. 1x Jabra Engage 45 SE Mono DECT Wireless Headset 1x Remote answer accessory (per selection: Avaya EHS, Cisco EHS, Polycom EHS, Yealink EHS36, or GN1000 handset lifter) Charging base Documentation Not included: USB-C charging cable.

Hardware: Each EHS variant is certified for a specific list of desk phone models (Avaya, Cisco, Polycom, or Yealink) — confirm your exact phone model against the list for your selection before ordering. The GN1000 lifter is a universal alternative that doesn't require EHS certification. Platforms: This headset is built for a desk phone environment, not a softphone/PC setup. For PC or UC platform use, the same headset pairs with a Link 400 USB adapter or Engage 65/75 SE base, both sold separately. What's the difference between the EHS options on the Jabra Engage 45 SE Mono bundle?Each EHS option is certified for a specific desk phone brand — Avaya, Cisco, Polycom, or Yealink — and only works with the phone models listed for that certification. The headset itself is identical across all options; only the remote-answer accessory changes. What if my desk phone isn't on any EHS-certified list?Choose the GN1000 handset lifter option instead. It's a universal remote-answer accessory that works with the vast majority of desk phones without requiring EHS certification for your specific model.
