Frequently Asked Questions

Is the charging stand included?
No. This SKU (9653-450-111) is the no-stand variant. For an otherwise identical Mono headset with charging stand included in the box, choose 9653-455-111.
Why DECT and not Bluetooth?
DECT uses dedicated wireless spectrum, so it doesn't fight Wi-Fi or other Bluetooth devices for bandwidth. You get a much longer range (up to 150m line of sight versus 10–30m for typical BT headsets), better audio stability in dense offices and stronger security (DECT Security Level C+).
Mono or Stereo — which should I choose?
Mono (single ear) suits reception, contact-centre and front-desk roles where you need to stay aware of colleagues or the room. Stereo suits roles where you want full immersion and music between calls — for the equivalent stereo version pick 9659-450-111 / 9659-455-111.
Will it work with USB-C laptops?
The included Link 400a adapter is USB-A. For USB-C laptops you can use a USB-A to USB-C adapter, or pick the 9653-470-111 / 9653-475-111 USB-C MS Mono variants for a native USB-C solution.
Singular Expert Insight
Choose this Mono DECT variant if your team is on calls 6+ hours a day, needs one ear free, runs Microsoft Teams, and your PCs have USB-A. The 57g weight makes a real difference over a full shift. If you also want a desk-docking solution for shared workstations or hot-desks, step up to the 9653-455-111 "Include Stand" SKU — same headset, same dongle, just adds the charging stand. If you don't need DECT range or Teams certification, the wired Evolve2 40 SE Mono (24189-889-899) is significantly cheaper.

Buyer's Guide

Buy it if
You run a Teams-first contact centre, need 150m DECT range, want one ear free for the room, and prioritise the lightest possible headset for full-shift wear.
Skip it if
You need a charging stand (pick 9653-455-111), prefer stereo for music between calls, or your laptop has only USB-C (pick 9653-470-111).
Also consider
9653-455-111 (same + stand) · 9659-450-111 (Stereo MS) · 9653-470-111 (USB-C MS Mono) · 9653-410-111 (UC Mono if not Teams-first).
